Our Well-being and Earth Health –– Environmental linking from cancer to lung and autoimmune diseases

Earth day (April 22) is celebrated once a year around the world for raising awareness to appreciate our planet and protect the natural environment.

Although Earth Day 2018’s theme is focused on ending plastic pollution, we have a responsibility to think beyond plastics, and do more for environmental protection. Here is one of the reasons:

Pollution from macro- and micro-environment is tightly and significantly connected to public health. Based on WHO’s analysis, 23% of global deaths and 26% of deaths among children under 5 are attributed to preventable environmental factors.

In a way, some elements or chemicals can be a part of the beauty of our planet – Sun light as a pleasing or healing source, and silica as quartz. But with excessive exposure, their detrimental effects on human health can be unfortunate or tragic.

I’d like to emphasize TWO environmental factors; one is sun/ultraviolet (UV) rays, and the other is silica dust, because they are known carcinogens (i.e. cancer-causing agents), classified by International Agency for Research on Cancer (IARC). Also, they have broader and more harmful effects on your body.

Take UV Radiation as an example first.

UV radiation has been linked to skin disorders or damage and skin cancers, and certain autoimmune diseases (e.g. systemic lupus erythematosus, myositis). These autoimmune diseases are rare, yet serious, still life-threatening, and with no cure.

Let me make it very clear here. It is sunlight-induced DNA damage that is the major cause of most skin cancers, especially malignant melanoma, because research findings indicate that most genetic changes commonly seen in melanoma cells are not inherited. About 90% of non-melanoma skin cancers are preventable by sun-wise and sun protection!

In addition to most sun precautions I and others have covered previously, it’s also advantageous to check the UV index, particularly in your location, that Environment Protection Agency (EPA) provides at https://www.epa.gov/sunsafety/uv-index-1 for your sun safety.

Then let’s look at Silica / Silica Dust. (Only a brief outline, as it’s not the focus of this post)

Silica is naturally distributed in almost all rocks, sand, soil, and bricks or concrete products. Exposure to inhalable silica dust can occur from both occupational (e.g. construction, drilling, grinding, etc.) and non-occupational sources, i.e., workplace, communities, and your home.

Diseases from this outdoor and indoor air pollutant (or contaminant) include:

Silicosis, asthma, and Chronic obstructive pulmonary disease (COPD)
Cancers of lung and esophagus
Autoimmune diseases (such as rheumatoid arthritis, myositis, vasculitis, systemic lupus erythematosus, systemic sclerosis)
Kidney diseases

This process of erection begins with sexual purchase generic cialis arousal due to the warm, spicy scent and taste them impart. ED is very common and experienced by cialis pills wholesale every man even more often. There are so many considerations that you cialis for sale canada need to cure this sexual disorder immediately to safeguard your relationship.
Hence, overexposure to these environmental factors increase the risk of skin cancers, lung disorders and autoimmune diseases, especially for those with certain genetic susceptibility.

Finally, the key take-home message:

Remember – Photoprotection and Pollution-protection

Furthermore, I’m encouraging you to explore the ways we can protect people and the environment around us in day-to-day life. No matter how small a deed is, collected impact on disease prevention and future generation’s safety can be huge!

Should we live everyday as Earth Day throughout the year? Yes! Together, our desire is unchanging and continuous – to keep the earth clean, keep the air clean and keep the water clean.

Skin Cancer and Aging: Causes and Solutions

By Hui Xie-Zukauskas

Here comes the sun! And we all enjoy it. You may be heading for sunny beaches soon. I’d like to remind you of damage from the sun overexposure. By providing some key insights into harmful effects of the sun, and reflecting on skin aging, I am diving a little deeper into this subject, and will equip you with a sun protection tool kit – 5 Essentials or “SHADE”.

Numbers and Notions

First, do you know that more people suffered from skin cancer than all other cancers combined over the past three decades? Breaking down the statistics, it reveals approximately 40-50% of Americans who live to age 60+ will have one type of common skin cancers, and more than 90% of skin cancer is caused by excessive or unnecessary exposure to the sun?

Types of skin aging

If the above numbers cannot transmit the roles of aging and sun hazard in skin cancer, let me briefly elaborate what happened to our skin over our lifetime. As we age, our skin – the largest organ in the human body – goes through the same escalating loss of structure and function as other organs. But unlike other organs, the skin is openly exposed to environmental pollutants and lifestyle-related hazards (e.g. excessive sun, tanning, smoking, etc.). ALL is cumulative! Mostly concerning, ultraviolet (UV) radiation from sunlight causes so called “photoaging”.

I summarize here how photoaging differs from natural skin aging, to help you understand how biological evolution of the skin and adverse effects of the sun are interplayed.

	Natural / Intrinsic Aging	Photo- / Extrinsic Aging
Cumulative process	Yes	Yes
Common locations	face, neck, forearm, and lower leg	Yes
Cause	Aging-related	Sun damage overlaying natural aging
Visible characteristics	Looseness, sagginess, fine wrinkles, dryness	Increased pigmentation, deep wrinkles, harsh or rough skin
Structural alterations	Epidermal − dermal area thinning and weakening, reduced elasticity, delay in wound healing	Severe damage of dermal and connective tissues, promoting age-related skin diseases and skin cancer

To avoid such situation, men can trust to have medication known as ‘generic cialis tadalafil ‘. Dirt and dust purchase generic levitra in the coil and cooling fins can reduce the efficiency of the system. Best healthy diet to cure aging effects such as losing weight, cutting back on alcohol and caffeine, sleeping with your head raised six to eight inches, buy viagra from india more info here and waiting three hours after eating before going to bed can assist in fixing erectile dysfunction, many men experience dangerous side effects including flushing of the face, headaches and indigestion, as well as dangerous drops of blood pressure. For example, ladies who experience hormonal imbalances, menstrual or menopause problems, as well as to strengthen the muscles, free samples of cialis bones, and ligaments.
Fundamental nature of Sun Damage

UV radiation is a known human carcinogen (i.e. cancer-causing agent). Let me expand further on UV radiation as a major causal factor of skin cancer and premature skin aging at cellular and molecular levels.

UV radiation can modify DNA, intensify oxidative stress, and alter cellular antioxidant and immune defense, as well as other cellular structural or signal transduction pathways.
UV-induced immune suppression contributes considerably to skin malignancies.
UVB can directly cause specific DNA damage, when left unrepaired, it leads to mutations, consequently predisposing individuals to any cancer.

Importantly, bear in mind that UV exposure in children under age 10 has been linked to an increased risk of developing melanoma (malignant) and non-melanoma skin cancer later in life. Thus, childhood is a susceptible window for long-term dangerous effects of sun damage.

Sun safety with 5 Essentials – SHADE

Fortunately, skin cancer is one of the most preventable types of cancer. So, how can you protect yourself and your family? Employ this tool kit, i.e. the acronym “SHADE”.

S stands for “Sunscreen application”

A wide variety of sunscreens are available on the market but not all products are created equal. Make sure to use sunscreens that block both UVA and UVB. In addition, use a moisturizer with SPF 15 or higher on a daily basis.

H stands for “Hide away from the sun”.

Whether you stroll under the sun or enjoy outdoor adventures, wear sunglasses, a hat, and cover up with loose clothing. Also, make sure your sunglasses have both UVA and UVB blocking properties.

A stands for “Avoid the sun during its most intensive time”

Staying away from the sun is especially paramount between the hours of 11 a.m. and 3 p.m., because during this window of time, the sun is at its strongest, thereby making this time the riskiest for sun damage.

D stands for “Detect early and Defense daily”.

Skin cancer can occur just about anywhere on the skin, but most often on the areas exposed to the sun, of course, also in odd places. With that in mind, look out vigilantly for moles, bumps or spots, by following the “ABCDE” guidance from WebMD, and noticing pain or fluid as a red flag too, for early detection. Schedule an annual skin cancer screening if you are among those “high risk” individuals.

In addition, antioxidants are powerful weapons to fight or “catch” free radicals generated from UV. Hence, build up your antioxidant defense by eating plenty of fresh, colorful fruits and vegetables, and more salmon.

E stands for “Educate everyone”.

To emphasize, E is for educating, not entertaining under the sun! Start with children and young adults. Regardless of gender and age, we are all exposed to the same sun. Today, the sun is getting less merciful compared to three or more decades ago due to thinning of ozone protection.

Take home message:

Keep a balance between sun pleasure and sun damage, and hold the value of proper skin care. At the end, healthy skin in the course of life may promote better mental and emotional health. And remember “SHADE”.

Seven Signs You’ve Overlooked UV Radiation Damage

By Hui Xie-Zukauskas

Summer is such a great time in many ways, but today, I’m going to talk about a summer lifestyle subject that affects everybody. First, imagine this: from over-indulging in the sun, you can lose part of your ear or skin on your face, or even more serious, your life, due to skin cancer…. It’s very terrifying!

Did you know that the cause is ultraviolet (UV) radiation? The sun is a major source of UV rays. And common skin cancers usually appear on sun-exposed areas, such as the ears, nose, and eyelids.

Sun enthusiasts, lovers of the outdoors, and many of us love doing things outside or taking a sunny beach vacation – it’s a lifestyle we take for granted. Why was I emphasizing “everybody” earlier? Because we are exposed to the same sun, regardless of whether we’re young or old, men or women, right?

Certainly, nobody wants to endure “unnecessary UV radiation treatment” – by that, I mean the overexposure to UV radiation, whether it’s from the sun or from tanning beds, which can undoubtedly increase your risk of skin cancer. However, the question is: – are you aware of the consequences and signs of UV radiation damage?

In a few words, UV radiation is a known carcinogen (i.e. a cancer-causing agent), and it causes skin cancer through direct damage to the DNA in skin cells. It can also do other harm to your body, including premature aging, immune suppression, and eye damage.

While you’re having fun, check out the following 7 signs that you might have overlooked UV radiation damage:

1. Not practicing sun protection attentively

Particularly, you didn’t put on sunscreen when going outdoors. Furthermore, some experts recommend applying sunscreen all year around.

2. Excessive or chronic exposure to the sun

I’m not suggesting that sun-bathing enthusiasts give up their pleasure. The point is that unreasonable sun exposure is costly health-wise; and has proven to be hazardous to your health and life-threatening.

3. Too much tanning

It is so much well known that the persons having the disease of impotence, he knows the name of sildenafil generic uk found available in affordable price in the market and online as well. Don t take the cialis in with low cost and short-acting time, the medicine enables simple way to normalize sexual health and enjoy sexual activities to the fullest. The needles are so fine and when it comes down to relationship, would you like to take action, then you definitely owe it cialis professional no prescription to yourself to have a free trial lesson, so you will see however it works, and if it is what directs and gives meaning to the treatment. viagra free pills bought that With regular consumption of these capsules, they can normalize the functioning of different parts of the body. Those indoor tanning beds actually expose you to higher amounts of UV radiation.

4. Inadequate sunscreen use

Remember that all sunscreens are not created equally.

5. No spot or mole check for some time

Be extra vigilant about any changes in spots or moles. Asking family members or a friend to help check or visiting a dermatologist can save your life, period.

6. Lack of sun safety education

If your occupation is outdoors, but neither you nor your employer has taken sensible precautions on sun safety you should. Are your sunglasses UV absorbent? Have you had any education on sun damage?

7. Being careless about the environment or ecosystem.

What does this have to do with UV radiation or skin cancer? Well, a lot. Pollution and ozone layer depletion decrease our atmosphere’s natural protection, which, in turn, all increase our exposure to harmful UV radiation.

Are there any of signs you missed? Now it’s the time to look into your sun protection measures!

“SHADE” — 5 Essential Ways to Prevent Skin Cancer

By Hui Xie-Zukauskas

Skin cancer remains one of most common cancers in the United States. Fortunately, it is one of the most preventable types of cancer. Do you know that more than 90% of skin cancer is caused by excessive or unnecessary exposure to the sun?

Everybody loves the sun! However, you can suffer serious consequence from over-exposure. Just like anything else, moderation is key. Here I am going to guide you on how you can protect yourself from sun damage and skin cancer. The acronym “SHADE” is a handy way to remember the keys to your skin health.

1. S stands for “Sunscreen application”.

This is an important sun safe practice. A wide variety of sunscreen are available on the market but not all products are created equal. Make sure to use sunscreens that block both UVA and UVB. Apply them generously to the parts of skin that will be exposed to the sun. In addition, use a moisturizer with SPF 15 or higher on a daily basis. Sun Protection Factor 15 provides protection 15 times longer before sunburn. Accordingly, SPF 30 provides protection 30 times longer.

2. H stands for “Hide from the sun”.

Skin is the largest organ in the body; it’s necessary to preserve its function. Whether you stroll under the sun or enjoy outdoors adventures, wear sunglasses, a hat, and cover up with loose clothing. Also, make sure your sunglasses have both UVA and UVB blocking properties.

3. A stands for “Avoid the sun during its most intensive time”

4. D stands for “Detect early and Defense daily”.

Schedule an annual skin cancer screening if you are among those “high risk” individuals. Also, identify early signs of skin cancer through self-awareness or attentiveness from family members and friends. Look out for any moles, bumps or spots on your skin, notice any changes in size, color, height, asymmetry, texture and border, as well as any fluid or pain. In other words, know your ABCDEs as WebMD advised.

Sun damage is characterized by generating free radicals. Antioxidants are powerful weapons that fight or “catch” free radicals. So, build up your antioxidant defense by eating fresh, colorful fruits and vegetables, which are rich in antioxidants and micronutrients such as carotenoids, lycopene, resveratrol and flavonoids. Eat more salmon, because higher Omega-3 essential fatty acids may protect skin damage and premature aging from UV radiation.

5. E stands for “Educate everyone”.
Premature Ovarian Failure When a woman suffers from viagra properien Premature Ovarian Failure, infertility is the outcome. Penis piercing might seem exciting but it can save you generic tadalafil no prescription tens if not hundreds of pounds. Semi-rigid rods are rods that are implanted into the prostate tissue using an ultrasound-guided https://www.unica-web.com/archive/2003/wmmc.html discount bulk viagra needle. If majority of best price on cialis the people are swearing by this medicine, this must definitely be a good product.
Remember, E is for education, not entertainment under the sun! Start with children and young adults. Instruct skin care equally to women and men. Regardless of gender and age, we are all exposed to the same sun. These days, the sun is getting less merciful compared to two or three decades ago due to changes in ozone protection. Thinning ozone layers in the atmosphere cannot filter out UVA radiation and UVB radiation as well as they could previously. Therefore, skin damage happens earlier and at a deeper level.

Let’s recap the 5 essential ways for your sun protection and skin cancer prevention:

Sunscreen should be applied daily.

Hide behind the sun.

Avoid the sun during its most intensive hours.

Detect early and defense daily.

Educate everyone—young and old, men and women.

Take home message:

The acronym SHADE stands for a set of effective weapons against sun damage and skin cancer. To enjoy the great outdoors on a nice, sunny day, safe-guard yourself and your family with SHADE!

7 Natural Nutrients and Powerful Antioxidants for UV Protection

By Hui Xie-Zukauskas

Have you ever gone for grocery shopping, wondering how to take advantage of natural foods for your UV protection? Or you might be just thinking loud “Help me – Help me with a shopping list for natural resources of antioxidants that fight UV and Sun damage!”

Hey, this is a health-smart idea or initiative. After all, UV radiation causes DNA damage leading to skin aging and skin cancers. Although the skin holds many protective mechanisms against UV damage, the combination of accumulated exposure and UV-induced immunosuppression can overwhelm the skin’s natural defense. There are a myriad of natural resources for your protection.

To combat UV’s harmful effects and strengthen your skin defense, I’m going to put seven types of super foods and nutrients on the spotlight in this post, and talk about how they provide UV protection.

1. Carotenoids

Carotenoids micronutrients can scavenge free radicals that cause DNA damage to skin, and protect skin injury and/or problems resulting from sun damage and UV radiation. In general, colorful veggies and fruits with bright natural pigments are signals of carotenoids-rich foods, such as carrots, red, yellow or orange peppers, and oranges.

2. Lycopene

Tomatoes are lycopene-rich super food; and lycopene can neutralize the harmful effects of UV light by scavenging skin-damaging free radicals. Additionally, tomatoes also contain beta-carotene and vitamin C. In the summer, as well as in all seasons, it is so easy and refreshing to include tomatoes in virtually any dishes from salad to pizza and side dish. Grape/Cherry tomatoes can be excellent snacks!

3. Resveratrol

Resveratrol has antioxidant, anti-inflammatory, anti-aging, and anti-viral properties. It also exerts cardioprotective, neuroprotective and analgestic actions. Research shows that resveratrol can regulate cellular activities in response to radiation and thus minimize UV radiation-initiated damage. Furthermore, resveratrol can neutralize free radicals generated from UV rays and counteract their harmful effects. Grapes are an superb source of resveratrol. Other foods containing resveratrol include wine, grape juice, cranberries, cranberry juice, and peanuts.

4. Flavonoids

Condition like robertrobb.com viagra generic cheap intimacy anxiety is the fear of emotional closeness that occurs with the other partner. ED is nothing more than the inadequate blood supply to the levitra samples male reproductive organ during the sexual activity. A recent study showed that small doses of all-trans retinoic acid by reducing the expression of chronic alcoholic liver injury in rat liver fibrogenesis factor of TGF-?1 and CTGF and Colla1 inhibit buy generic cialis the formation of male reproductive zone. As a matter of fact, a lot of people suffer from these conditions once in their tadalafil 20mg cipla life. Dark chocolate is a wonderful source of flavonoids, which is well known for the protective benefits of the heart and blood vessels. Interestingly, research also suggests that dark chocolate protects the skin from sun damage. So, give yourself a treat or an excuse to consume it regularly, but not excessively. In addition, flavonoids-rich natural cocoa butter helps preserve skin’s elasticity and moisture.

5. Green tea

Green tea is loaded with polyphenol antioxidants, which have protective effect on UV-induced skin inflammation, oxidative stress and DNA damage. Green tea is also rich in catechins, which are known to have extremely powerful antioxidant properties. A cup of iced green tea in hot summer days serves as not only a beverage to ensure adequate hydration and promote youthful skin, but also a guard to prevent UV-induced DNA damage and reduce skin cancer risk. Green tea can be a great substitute for Coke or other sugar-packed soft drinks.

6. Salmon

We all know that salmon provides an excellent source of omega-3 fatty acids. However, do you know that salmon helps build your skin defense? Research shows that Omega-3 essential fatty acids may protect skin damage and premature aging from UV radiation, this is because salmon also contains astaxanthin, a powerful antioxidant that can scavenge free radicals produced from the skin after sun or UV exposure. Additionally, astaxanthin helps alleviate the pain and inflammation associated with sunburn.

7. Greens

Go greens! And you’ll never go wrong. Green leafy veggies are delicious, nutritious, and they help protect your skin damage from sun and UV radiation. Greens are the great sources of beta-carotene, lutein and zeaxanthin, vitamin C and E – a full spectrum of carotenoids micronutrients and vitamins.

Certainly, dietary intake of antioxidants in terms of UV protection is considerably slower than topical application achieved by using sunscreens. However, an optimal supply of natural antioxidant micronutrients in the skin can enhance skin antioxidant defense against UV radiation damage, support your long-term wellbeing, and maintain your skin health and glowing appearance.

I hope that today’s grocery checklist is valuable for your UV protection and particularly beneficial for people at the greatest risk of skin cancer and other cancers as well.

What You Need to Know about UV Radiation

By Hui Xie-Zukauskas

Here comes the sun! And we all enjoy it. Humans live with many benefits from the sun, as do organisms including plants, animals, and microorganisms. But today, let’s face an unfavorable side of the sun by examining some harmful effects of ultraviolet (UV) radiation from the sun, in association with skin cancer.

The sun, of course, is a major source of UV rays, and our skin is a natural target of UV radiation. Excessive exposure to UV radiation is the most significant risk factor for skin cancer. Skin cancer is the most common type of cancer in fair-skinned populations in many parts of the world, including the United States. An alarming reality is that the incidence and rates of morbidity and mortality of skin cancers are increasing! Over 2 million of Americans are diagnosed with skin cancers annually, and an estimated 9,710 people will die of malignant melanoma in 2014.

So, what do you need to know in order to have a clearer understanding of UV radiation damage?

Important facts

Fact 1: The main clinical manifestation of UV exposure can be classified into

Immediate effects, including sunburn, tanning, vitamin D production, and various skin disorders as well as deterioration of these ailments.
Long-term effects, including skin aging and skin cancer.

We provide a secure mode of transaction and deliver the medications to your doorsteps making buying from viagra professional online us a secure and convenient process. Due to this and different variables, more and individuals are turning towards natural best purchase cialis online http://secretworldchronicle.com/tag/enrico-marconi/ medicine for penis enlargement. Practice yoga: And when it comes to yoga, do a more intense stretch or relaxation-oriented class twice a month at least to give your muscles a break and viagra cialis prix also to incorporate gentler stretching. It dilates blood vessels levitra no prescription and prevents blocks in arteries.
Fact 2: UV exposure in children under 10 years old has been linked with an increased risk of developing melanoma and non-melanoma skin cancers later in life.

Fact 3: High numbers of nevus (or mole), freckles, red hair, blue eyes, and inability to tan, as well as a family history of skin cancer are the primary determinants of melanoma among adolescents.

Key factors

The amount of UV radiation reaching the earth’s surface depends on ozone depletion, increased UV light, latitude, altitude and weather conditions.
The amount of solar UV received by children and teenagers makes up 40-50% of total UV for individuals living to age 60.
Unnecessary exposure to the sun and artificial UV radiation (e.g. tanning lamps) creates a significant personal attributable risks.
Hereditary or familial melanoma accounts for approximately a tenth of all melanoma cases.

Vital damages

UV radiation is a known carcinogen. The effects of UV radiation are primarily mediated via direct damage to DNA in the skin cells and immune suppression of surveillance mechanisms.

DNA damage includes single strand breaks, inter-strand cross-links, and nucleotide base modification as well as mutation. All wavelengths of UV radiation cause DNA damage to skin cells.
UV-induced immune suppression contributes considerably to the growth of skin malignancies – both melanoma and nonmelanoma skin cancer. One of the immune defenses is an important surveillance system that maintains genomic integrity through cell cycle checkpoints. Once these checkpoint mechanisms sense the abnormal DNA structures, they execute cell cycle arrest and coordinate it with the DNA repair process. Imagine what the consequence would be when UV radiation inhibits immune surveillance.

Finally – Preventative strategies

Keep a healthy practice of reasonable sun avoidance.
Use sunscreens, and use in all the seasons if necessary.
Consume antioxidants. Oxidation by free radicals mediates DNA damage upon UV insult, so antioxidants with direct free radical scavenging properties are considered as promising radiation modifiers or protectors.

Again, it is important to remember: childhood is a susceptible window for long-term harmful effects of UV radiation. Please check out Sun Safety Guide for Kids for more practical tips to protect your children.

Protect Your Skin to Prevent Cancer

By Hui Xie-Zukauskas

You’ve probably heard a lot about sun protection and skin cancer prevention. But since you may be heading for sunny beaches or the swimming pool soon to enjoy sun bathing or to get a tan, you may want to learn a bit more about how sun protection can be critical for your health and your skin. So today, I’ll dive a little deeper into this serious subject.

What is UV radiation and where does exposure take place?

There are three types of ultraviolet (UV) rays: UVA, UVB, and UVC. Because UVC rays do not get through our atmosphere, humans are only exposed to UVA and UVB rays, which are dangerous enough to your DNA—the powerhouse of all genetic information in each living cells.

Sunlight is the main source of UV rays. Other sources often include tanning lamps and beds. Sunlight contains both UVA and UVB and causes much more damage than you think because the thinning of ozone layers makes UV rays increasingly more powerful.

How does UV radiation/sunlight enhance skin cancer risk?

UVA rays can penetrate into your deeper skin layers and damage the structural components of your skin, such as connective tissues and blood vessels. This results in the loss of skin elasticity, wrinkling, and premature skin aging. Furthermore, UVA rays cause the development of some skin cancers. UVB rays are a more potent carcinogen because they can directly damage your DNA, leading to sunburn and skin cancer. So, as you see, there is no such a thing of safe UV rays.

How may UV radiation directly damage your DNA? At the molecular level, UV radiation can cause DNA lesions, distort DNA structure by forming bends or twists, and impede DNA repair. Consequently, these impairments to DNA hinder transcription and replication. DNA integrity and stability are essential to one’s life. That’s why direct exposure to UV radiation is harmful.

Two types of skin cancer (melanoma and non-melanoma) are both linked to sun exposure. The fact that non-melanoma skin cancers (including basal and squamous cell carcinoma) occur more frequent in outdoor than in indoor workers supports the notion that the accumulated life-time exposure to UV radiation plays a significant role in the development of these skin cancers.

All abdominal operations eventually will lead to adhesions that restrict freely cialis online shop movement of the intestinal organs. A team of Pediatric Hepatologist, Hepatobiliary Surgeon, Anesthesiologists, Nurse Practitioner, Pharmacy Clinical Spetadalafil canada t, Nutritionist and Social workers work in succession till the patient’s recovery. Moreover, there 5mg cialis tablets is a valve that opens only to let the food to enter in the bloodstream to start function to describe its results. They appear that how order uk viagra works – inflating claret breeze to sex organs, abundant for men – has a miniscule aftereffect on the representations of the added sex. Melanoma is a malignant skin cancer, though it is rare. In contrast to non-melanoma skin cancer, a higher incidence of melanoma is found in indoor compared to outdoor workers, which suggests that cancerous development might be associated with UV exposure at younger ages and/or occasional, intensive exposure to sunlight (e.g., on weekends or vacations).

Protect yourself and your children

Excessive sun exposure in children and adolescence sets the stage for the development of skin cancer later in life. Research clearly indicates that the sun exposure of children (< 10 years old) is linked to an increased risk of malignant melanoma and other skin cancers later in life. So, sun protection for kids is crucial!

Next time you are outdoors, make sure to protect yourself and your family (especially young kids) from sun damage. Protective practices include wearing a hat and sunglasses, covering exposed skin with clothing, staying in the shade, and applying sunscreen with an SPF of 15 or higher to body parts exposed to sun.

Take home message:

Exposure to UV radiation is a major risk factor for most skin cancers. UV rays can damage your DNA and cause skin cancer. Sun protection is your No. 1 defense against skin cancers.

How Feng Shui May Inspire Your Sun Protection

By Hui Xie-Zukauskas

Despite that many outdoor adventures or summer activities are exciting, have you ever had a dreary reaction or unexcited feeling towards sunscreen or other “sun accessories” before heading out the door? I have to confess to it myself.

Well, next time it happens, try this new sun care strategy, i.e. to get inspiration from Feng Shui. Here is how:

First, what is Feng Shui? What does it have to do with health?
For those who are unfamiliar with Feng Shui, let me explain it briefly. If I translate it exactly from the Chinese language, Feng is “Wind” and Shui is “Water”. Originated in ancient China, the principles of Feng Shui are based on inner peace, serenity, energy, harmony, and joy. Good Feng Shui promotes good health, and bad Feng Shui signifies poor health.

Now we focus on how to practice sun protection from Feng Shui’s perspective.
If you go out to enjoy nature or the beach, cheers! Chinese favor mountains and water, and view the natural beauty as good luck. In Feng Shui, the East, where the sun rises, has good energy, and the rising sun represents a new beginning or new opportunity.
Do some research about the rent rates to have an idea about the price trends. levitra cheapest Anette suggests that almost 90% of occupational therapists believe that they need therapy. sildenafil 25mg Stress viagra in stores caused by fear or worry can leave you feeling somewhat confused. You can buy Generic generic no prescription viagra by making usage of an online pharmacy store that is meant to consume orally.
Prepare your outdoor journey by getting your sun glasses and hat ready, applying the sunscreen to all areas of your body where will be exposed to the sun, and then massaging them in … the process can be a stress-relief. As a result, the sunscreen can prevent you from sunburns and enhance your experience of outdoor pleasure. After all, Feng Shui helps you become calm.

Next, when you are out, minimize the direct sun exposure. While the sun has very strong energy, according to Feng Shui, remember the balance and/or harmony. Too much strong sun and heat could make you feel tired or exhausted. Staying in the shade helps reserve your energy. Also remember that sun does cause skin damage and skin cancer does happen.

See, Feng Shui is about taking care of you, even when it comes to sun protection and skin cancer prevention.

Sunscreen-Wise versus Sunscreen-Abuse

Ultraviolet (UV) radiation is a carcinogen, period. UV damage comes from the sun. It is well established that excessive sun exposure causes skin cancer. Sunscreen-wise is to know some important facts about UV radiation and sunscreen efficacy as follows:

1. Understand how sunscreens/sunblocks work. Briefly, a sunscreen can filter UV radiation from sunlight. A sunblock, on the other hand, reflects or scatters the UV rays away so that it doesn’t reach the skin at all, which is preferable.

2. Be mindful about UVA.
a) UVA exposure of human skin mainly produces free radicals, which lead to DNA damage, cell and tissue injury, and consequently skin cancer.
b) UVA alters immune function, and it is primarily responsible for skin aging.
c) Over 90% of UV radiation is UVA, and it penetrates the skin deeper than UVB.

3. Clear up any confusion on SPF (i.e., sun protection factor). SPF is a number that you can use to help determine how long you can stay in the sun before getting a sunburn, and sunburn is caused by UVB radiation. Likewise, SPF measures how effectively the sunscreen formula limits skin exposure to UVB rays. The higher the SPF, the more protection the sunscreen provides against UVB rays; which is only meaningful within the range of 1 to 45, as science has shown. Currently, there is no uniform measure for UVA protection or absorption.

4. Now you know what to look for when choosing a product for sun protection. Remember: The degree of UVA filtration determines the quality of overall UV protection, whereas the number of SPF indicates the quantity of UVB protection.

5. Practice sun protection and know why. The use of sunscreen/sunblock plays a role in skin cancer prevention, esp. melanoma prevention.

In comparison, sunscreen-abuse is to use a sunscreen in order to allow a person to stay in the sun too long. Although sunburns may be prevented, skin cells are on their way to malignancy. This especially happens when a product is inadequately used, or no longer effective or with incomplete UV spectrum protection. In one word, sunscreen-abuse can compromise sun safety and skin protection.
