For those of us who spend extended periods of time off-shore, on the road or simply in the sun, protecting ourselves from the UV radiation is no laughing matter. 1 in 5 people will get skin cancer in their lifetime (1 in 3 Caucasians) and spending excessive time on the outdoors only increases the amount of UV radiation we expose ourselves too.  Watersports athletes must be especially careful; water can increase the potency of the suns UV radiation by as much as 50%. Here at Watermans: Applied Science we feel it is important to educate oneself on sun damage and the issues and influences associated with skin cancer, advanced aging, and other complications associated with sun exposure. Please keep reading for more useful information on skin cancer and effective protection techniques.

 

 

Stress Hormones, Sun Protection and Athletic Performance
One of the more misunderstood and under rated benefits of utilizing a proper skin protection plan is increased athletic performance. Sun exposure is caustic to the skin, the largest organ in the human body, and the body’s immediate reaction to this type of invasion is to react as if under stress.

When under stress the body produces stress hormones, including Cortisol. These hormones play an important role in our natural fight or flight response by signaling blood vessels to dilate and blood pressure to rise in preparation for dealing with whatever is causing stress.

This is great if one needs to make a quick get away, but for an athlete in the middle of competition the release of stress hormones can be detrimental to performance; inflammation of the digestive tract contributes to digestive problems and inflammation of the airways contributes to asthma and other respiratory problems that will negatively affect performance. More over, visible inflammation of the skin commonly referred to as Sunburn takes blood away from vital organs and muscles where it is needed most during competition. All of which affect the body’s ability to maintain stable energy levels and consistent performance.

By using a proper protection plan, including protective clothing, an athlete can stave off the inevitable release of stress hormones more affectively and maintain peak performance for longer than without.


 

The Skin
The skin is the largest organ in the human body, serving as a protective barrier between the body’s internal environment and the outside world.  It controls our temperature and protects us from environmental influences, but its ability to protect itself against the harmful effects of the sun’s UV radiation is limited.



Skin Cancer
Skin cancer is the most common form of cancer in the United States. More than 1 million skin cancers are diagnosed annually. Squamous cell carcinoma is the second most common form of skin cancer. More than 250,000 cases are diagnosed each year, resulting in approximately 2,500 deaths each year. One in 5 Americans and one in 3 Caucasians will develop skin cancer in the course of a lifetime. More than 90 percent of all skin cancers are caused by sun exposure. A person's risk for skin cancer doubles if he or she has had five or more sunburns.

 

 

 




UVA/UVB radiation
What is radiation? The sun gives off ultraviolet radiation that is divided into categories based on the Wavelength.
UVC - 100 to 290 nm (does not penatrate the earths atmosphere)
UVB - 290 to 320 nm
UVA - 320 to 400 nm

UVA - UVA was once thought to have a minor effect on skin damage, but now studies are showing that UVA is a major contributor to skin damage. UVA is a high-energy wave that penetrates deeper into the skin to do its damage. The intensity of UVA radiation is more constant than UVB without the variations during the day and throughout the year. UVA is not filtered by glass. UV-A can be further subdivided into UV-A I, or far UV-A (340-400 nm), and UV-A II, or near UV-A (320-340 nm).

UVB - UVB affects the outer layer of skin, the epidermis, and is the primary agent responsible for sunburns. It is the most intense between the hours of 10:00 am and 2:00 pm when the sunlight is brightest. It is more intense in the summer months accounting for 70% of a person's yearly UVB dose. UVB does not penetrate glass.

 



Skin Types
Everyone has a different skin complexion genetically determined largely by melanin content. To simplify the huge variation in the different types of skin, all people are categorized into one of six Skin Types (based on the Fitzpatrik Phototype Scale).

 

Depending on your skin type, you have more or less natural Sun protection and susceptibility to sun-induced skin damage. People with lighter hair and fairer skin (therefore with a lower Skin Type value), are more at risk of developing both Basal Cell Carcinoma and coetaneous Malignant Melanoma (Elmets et al, 2001). Knowledge of your Skin Type is vital in determining your safe period of sun exposure calculated with the UV Index for that day. It is also required to calculate how your safe period of sun exposure is extended with the applicable SPF (Sun Protection Factor) of the sunscreen that you are using. Below is a list to help identify your skin type and aid in determining your sunscreen needs.

 
Type # 1 – Ivory white, no tanning ability, always burns easily.
Type # 2 – White, minimal to weak tanning ability, high inclination to sunburn.
Type # 3 – White, low tanning ability, moderate inclination to sunburn.
Type # 4 – Beige-Olive, lightly tanned, moderate tanning ability, very low inclination to sunburn.
Type # 5 – Moderate brown or tanned, sun insensitive skin, very low inclination to sunburn.
Type # 6 – Dark brown or black, sun insensitive skin, never burns.

 



Sunscreen is not a one-size-fits all product

The FDA, CDC, and Skin Cancer Foundation recommend choosing a sunscreen based on your specific needs. You should not be using a higher SPF sunscreen then you need to, because the concentration of chemicals relative to the protection they afford is much higher in products with a higher SPF rating.
 


Inorganic vs. Organic sunscreen

Watermans: Applied Science follows the recommendation of the CDC, FDA, and Skin Cancer Foundation and uses a mix of organic and inorganic sunscreens. The organic sunscreens are commonly known as “chemical.” These agents protect against UV by absorbing the energy from UV rays. Inorganic sunscreens, such as metal oxides or particulate UV filters, are often termed “physical” or “mineral.” The metal oxides, namely titanium dioxide and zinc oxide, are insoluble particles, which absorb and reflect UV. The differences between these active ingredients are primarily based on their solubility, with organic UV filters existing in solution and physical ones being suspended or insoluble. The effectiveness of physical/mineral sunscreen agents depends on their presence on the outer layer of the skin and the effectiveness of the organic sunscreens is dependent on the skins ability to absorb the sunscreen agent. For this reason it is important to find a good mix of both physical and organic sunscreen agents in order to ensure consistent broad-spectrum protection.

 

For your protection, Watermans always defers to the recommendation of the Skin Cancer Foundation, the CDC and the FDA when choosing active ingredients.

“In all cases we recommend a broad-spectrum sunscreen offering protection against both UVA and UVB rays… (Such sunscreens) combine several different active chemical sunscreen ingredients in order to provide broad-spectrum protection. Usually, at least three active ingredients are called for. These generally include PABA derivatives, salicylates, and/or cinnamates (octylmethoxycinnamate and cinoxate) for UVB absorption; benzophenones (such as oxybenzone and sulisobenzone) for shorter-wavelength UVA protection; and avobenzone (Parsol 1789), ecamsule (Mexoryl), titanium dioxide, or zinc oxide for the remaining UVA spectrum.”
