Sunscreens provide inadequate protection from UVA - Divine Skin - Sunscreens provide inadequate protection from UVA
Divine Skin
Studies show that people often have the mistaken notion that the higher the SPF number of the sunscreen they use, the longer they can stay in the sun. In addition, the protection from sunscreens is understood as being the amount of time you can stay in the sun before getting burned. Research in the last several years shows that damage will occur long before you get pink or sunburned, exposure to the sun at what is considered safe levels still leads to photo aging and micro scars. The micro-scars compound over time and after many years lead to visible signs of aging.
Another problem is that the vast majority of sunscreens only provide protection from UVB but very little protection from UVA, wavelengths that appear to be the principle cause of photo-aging and lowered collagen production in the skin.
To prevent premature aging, sun damage, and skin cancer, you need to protect yourself from the harmful ultraviolet (UV) rays of the sun. Sunscreen alone will not protect you. The best way to protect yourself is to avoid the sun altogether during the middle of the day, especially between the hours of 10am and 4pm.
However, simultaneously several studies have confirmed that under-exposure to the sun may lead to other health problems. A number of recent articles in medical journals report that the vitamin D made in the skin in response to ultraviolet B radiation may protect against certain diseases, including cancer of the breast, colon and prostate.
The bottom line is that it is important to practice safe sun exposure, without becoming sun-phobic. As always, a well balanced lifestyle is the key to optimal health. It takes just 15 minutes per day in the sun, preferably either earlier in the morning or late in the afternoon, to get all the benefits of sun exposure without the negative side effects.
