Suncare on the Slopes
June 25, 2009 by admin · Leave a Comment
Higher altitude means increased levels of harmful UV exposure compared to sea level areas. UV exposure increases 8-10 percent with every 1,000 feet above sea level. At an altitude of 9-10,000 feet, UV may be 45-50 percent more intense than at sea level. In addition, snow reflects about 80 percent of the UV light from the sun, meaning that you are often hit by the same rays twice. This only contributes to the problem, further increasing the risk for skin cancer.
The combination of higher altitude and ultraviolet (UV) rays reflected by the snow puts skiers and snowboarders at an increased risk of sun damage and ultimately, skin cancer. More than 90 percent of all skin cancers are caused by sun exposure. It’s easy to associate winter with frostbite and windburn, but most people are unaware that UV rays can be even more damaging on the slopes than on the beach,it’s important to take proper precautions while on the slopes.
Both snow and strong wind can wear away sunscreen and reduce its effectiveness, so you have to take extra precautions. To protect your skin from the bitter cold, heavy winds and winter sun, follow these important sun protection tips:
• Use a broad-spectrum sunscreen with an SPF of 15 or higher whenever you spend time outdoors. Apply 30 minutes before hitting the slopes.Be aware that the sun’s reflection off the snow is strong even on cloudy days.
• Apply sunscreen liberally and evenly to all exposed skin – most skiers and snowboarders do not use enough sunscreen and therefore do not get the maximum protection.
• Use a more moisturizing sunscreen. Winter conditions can be particularly harsh on the skin.
• Be sure to cover often-missed spots: lips, ears, around eyes, neck, underside of chin, scalp and hands.
• Always wear a lip balm with an SPF 15 or higher. Lips are even more sensitive than most parts of the skin.
• Reapply at least every two hours, and more often after sweating or exposure to wind and snow.
• Carry a travel-sized sunscreen and lip balm with you on the slopes. Reapply on the chairlift, especially after a long, snow-blown run.
Cover up.
• Wear items like ski masks, which will cover most of the skin, leaving very little exposed to the wind and sun.
• UV-blocking sunglasses or goggles that offer 100% UV protection and have wraparound or large frames protect your eyelids and the sensitive skin around your eyes, common sites for skin cancer and sun-induced aging. The sun’s rays and glare can impair your vision, so it’s important to wear sunglasses or goggles to clearly see the terrain. Plus, it will increase your enjoyment and performance while skiing.
Be mindful of time spent in the sun, regardless of the season.
• Keep track of the time you spend in full sunlight. If possible, ski early in the morning and later on in the day, before 10AM and after 4PM. This helps avoid long lines and decreases the amount of time spent outdoors in the most intense hours of sunlight.
• If you are on the slopes for most of the day, take a few breaks indoors to reapply sunscreen.
• Drink plenty of water to avoid dehydration from the sun.
Enjoy the winter season, but be sure to take care of your skin to avoid the damage the cold season can cause.
The first organization in the U.S committed to educating the public and medical professionals about sun safety, The Skin Cancer Foundation is still the only global organization solely devoted to the prevention, detection and treatment of skin cancer. The mission of the Foundation is to decrease the incidence of skin cancer through public and professional education and research.
FAQ on Sunscreens and Sunburns
June 25, 2009 by admin · Leave a Comment
1. “How Much Sunscreen Should I Apply?”
The average user of sunscreen tends to use significantly less sunscreen than the amount required to achieve the SPF listed on the container.
2. “How Often Should I Apply Sunscreen When I’m Out In The Sun?’”
Many experts recommend that frequent application during sun exposure is required. However, a group of children were tested by spreading on 1 application of sunscreen to one side of their bodies, and four applications to the other.
They then spent 6 hours in the sun. One application provided the same level of protection as four applications, confirming the adequacy of a single daily application of a sunscreen in that situation.
3. “How Long Before Sun Exposure Should I Apply Sunscreen To My Skin?”
As molecules of sunscreen are present in their active state in the sunscreen, sunscreens work immediately upon application. The only reason for application early is to allow absorption into the skin so that the sunscreen is less likely to be washed off, should the person be entering the water. Even so, modern sunscreens are quite resistant to removal from the skin.
4. “Sun Protection Factor (SPF) – What Is It?”
SPF is the ratio of the minimal ultraviolet dose required to produce redness with and without a sunscreen. For example, if it took ½ hour for your skin to become sunburned without any sunscreen, then for a sunscreen that has a 15 SPF rating, you could stay in the sun for 15 times longer (or 7.5 hours) before you get sunburned. This is provided, of course, that you’ve applied the sunscreen properly so that you’re getting the prescribed protection.
5. “Reactions To Sunscreens?”
Sunscreens can be both an irritant and an allergen, though allergic reactions are rare. Irritant reactions, however, abound. One classic error in sunscreen application is to put a large amount of sunscreen on the forehead. Perspiration and gravity can cause the sunscreen to migrate down your forehead into your eyes, causing a stinging sensation. Some people attribute this to an allergic reaction and discontinue use. It’s also important to wash your hands after applying sunscreen, since rubbing your sunscreen covered finger near your eyes can induce an irritant reaction.
6. “Why Is It Important To Use Sunscreens During Childhood?”
It appears that a great deal of time can elapse between actual sun damage and the development of skin cancer or other skin problems like photoaging. Therefore, it is important to protect your skin from an early age when you are out in the sun.
7. “Sunscreens And The Elderly?”
Many elderly people can become quite obsessed by sun avoidance, and their quality of life can suffer. Sometimes, if they are diagnosed with an actinic keratosis or basal cell carcinoma, they can become anxious and almost leap from shadow to shadow. However, few of them are likely to develop new skin cancers from present sun exposure. As long as they are prudent about avoiding excessive sun exposure and protecting their skin to prevent sunburn, they can continue to enjoy time outdoors.
8. “Can Sunscreens Prevent Cancer?”
There is clear evidence that sunscreens are helpful in preventing actinic keratoses, which are warty lesions that can occur on sun-exposed skin of the face or hands. Research has shown that these lesions can develop into a cancer called squamous cell carcinoma, and that this is linked to a cumulative exposure to the sun.
However, there is surprisingly little evidence that sunscreens have much effect in preventing another kind of skin cancer called basal cell carcinoma, or for malignant melanoma. For malignant melanoma and for basal cell carcinoma, the character and timing, that is, the type of sunlight and your age at the time of the exposure to the sun appears to be more important than the cumulative dose.
