For a golden, youthful glow, most people rely on tanning beds and laying out to help bronze their skin. As for short term benefits, tanning looks like an excellent option for giving you that outdoorsy, healthy appearance. However, in the long term, sunlight is actually way more harmful for your skin than it is beneficial. This article will look at how sunlight and tanning beds affect your skin, and several methods to prevent these negative effects.
Sunlight is actually radioactive. During the span of nine months, someone can get between 90-100 millirads of radiation from sunlight alone. Sunlight is composed of three types of ultraviolet rays, called UV rays. UVC is typically absorbed by the atmosphere's ozone layer, but as our ozone layer thins, UVC can hit our skin, causing light sunburn in small doses, yet large amounts can be fatal because they so directly damage our DNA.
UVB rays are a common yet dangerous radiation wave, and they are known as the "tanning" rays. UVBs only penetrate the thin top layer of our epidermis, causing our skin to create more melanin, or the darkening pigment that leads to a tan. However, this can also lead to age spots. The other more common type of sunlight comes in the form of UVA rays. Once thought to be the "safe" rays, exposure to UVA rays are actually highly hazardous as well, since they can penetrate much deeper than UVB rays.
Tanning beds rely mostly on UVAs to tan their patrons. Many tanning bed companies may argue that they are safe ways to get tan, but in reality, the International Agency for Research on Cancer has upgraded tanning beds to the highest level of danger-a known carcinogen to humans. Additionally, tanning beds provide UVA rays that are 10 to 12 times more potent and deadly than rays from the sun itself.
Now, we must look at what the rays actually do to your skin. Not only do some of them promote the production of melanin, but the radiation damages your DNA so that it cannot reproduce into healthy skin cells. Also, absorbing sunlight causes your body to release free radicals, which can further damage your body by stealing electrons from the atoms that make up your protein, DNA, and cells. These cause mutations which age your skin by breaking down the collagen, leading to wrinkles. Also, with the mutations, skin cancer becomes much more imminent.
To help protect yourself from the harmful effects of sunlight, stay out of the sun when it is strongest during the middle of the day. If you know that you are going to be outside or in the sun, wear long sleeves and other protective clothing such as hats. Applying sunscreen is another great way to defy the damages accrued by time in the sun. Of course, some people may argue that we need some sunlight to produce vitamin D, and that's true. However, only very small amounts of sun exposure are necessary. This can be about 15 minutes of sunlight, 3 times per week. Take note, though, that this varies greatly depending upon your skin type, location, and the season.
Although shielding yourself from the sun's rays is definitely a large step in protecting your face from the wrinkles of age, sometimes we need more than just SPF to help fight our creases. For more information on wrinkle-fixers and other skin issues, check out this facial cosmetic surgeon today.
