On a beautiful, sunny day, there's nothing more pleasant than enjoying a day at the beach, a picnic in the park or just puttering in the garden. But, in the joy of the moment, it's common to forget the importance of protecting your skin from exposure to the harmful ultraviolet (UV) rays of the sun. Remembering this step will help reduce the potential risk of skin cancer, as well as prevent the accelerated aging of the skin. While many believe that the few moments used to apply sunscreen before the fun begins is sufficient, unfortunately, it's not always that straightforward.
Even when someone makes an effort to protect their skin from overexposure to solar radiation, it's not uncommon for something to go wrong. Many people have had an unexpected sunburn sneak up on them, with all of the discomfort that attends it. More than just a red, painful sunburn with peeling skin is at stake, however: The powerful UV rays from the sun can also have long-term health effects. Continued exposure to UV radiation reduces levels of vitamin A in the body, which diminishes the ability to fight infection. The thick, scaly or crusty patches of skin, called actinic keratosis, is caused by UV exposure and is a pre-cancerous condition that affects more than 58 million Americans.
The high-energy UVB bandwidth of ultraviolet radiation is responsible for reddening of the skin (erythema) and can cause direct damage to DNA. The UVA wavelengths, which penetrate deeply into skin tissues, damage the supporting collagen and elastin cell structure, causing skin to lose its tone and results in lines, wrinkles and sagging skin. This band of wavelengths also causes highly reactive chemical changes, resulting in the production of hydroxyl and oxygen radicals that can lead to cancer. More than 90% of non-melanoma skin cancers are associated with exposure to UV radiation; more than 2 million people diagnosed with skin cancer each year – a number greater than all breast, prostate, lung and colon cancer cases combined.
Overexposure to the sun can easily sneak up on people, even when they try to take precautions. In a recent survey, more than half of all adults in the United States reported at least one episode of sunburn in the previous 12 months. The causes of these accidental sunburns can be attributed to one or more of these common mistakes:
UNDERESTIMATING THE POWER OF THE SUN
It doesn't take a hot day with the sun beating down from a relentlessly cloudless sky to cause a sunburn. More than 80% of the sun's UV rays reach the earth's surface even during an overcast day. Meanwhile, approximately 85% of UV rays are reflected back up from the surface of water and light-colored ground cover as sand, snow and concrete.
NOT ENOUGH SPF COVERAGE
Sunscreen is rated with a number called the skin protection factor (SPF), which measures the length of time it will protect against sunburn. Misunderstanding how the ratings are derived can result in under-use of sunscreen, in some cases. Also, the use of broad-band sunscreen, which filters both UVA and UVB wavelengths, is sometimes neglected; to be effective, the entire range of the UV bands should be covered. Also, some people simply do not apply enough sunscreen; directions for the amount to be used are always provided on the packaging.
LOSS OF SUNSCREEN
Working or playing in the sun can cause the amount of sunscreen on the skin to be reduced. Perspiration and contact with water – everything from swimming to water gun fights – can wash sunscreen off the skin. Water-resistant sunscreen isn't a simple solution: No brand claims to be waterproof as that statement is prohibited by the FDA. Of course, rubbing the skin can remove sunscreen. Actions ranging from drying off with a towel after swimming, taking a shirt or other covering off or on, the rub of a scarf against the back of the neck or just wiping a sweaty brow can all remove the protective layer of sunscreen. Even if an individual is careful to avoid any of those actions, sunscreen will begin to lose its effectiveness after a period of time as its protective ingredients react with the UV radiation. Reading the label and renewing sunscreen at appropriate times are the most effective ways to maintain the protection offered by any sunscreen.
MISSING A SPOT
It's easy to forget to cover an area of skin that can be exposed to the sun at some point. There are just some places that can be overlooked when getting ready to enjoy some time in the sun.
With that last point in mind, it's a good idea to take special effort to remember some of the most often overlooked areas of the body. Make sure that the following spots get covered with sunscreen or otherwise protected from the powerful UV rays of the sun:
Enjoy warm, sunny days – even the not-so-sunny ones – with a trip to the beach, an old-fashioned picnic or a pick-up ball game. Just remember to keep skin protected from the harsh effects of UV radiation from the sun, even those places that are hard to reach or easy to overlook.
If the sun creeps up on you or your loved one and your skin is compromised with a burn, over-the-counter treatments can be effective in reducing the discomfort. Cool showers and the application of aloe vera or chamomile can help with the pain. Also, Tylenol, Aleve, Advil or Aspirin can help with the stinging and reduce the fever caused by a sunburn. Be sure and speak with a healthcare provider before selecting a non-prescription medication.
