Is it true that tanning can protect you from skin cancer?
Most people think that exposure to sun rays is the first cause of skin cancer. They are right. However, it does not mean that bronze skin has to be more damaged than the kind that always has been protected from the sun. Several decades of testing proves that people with tanned skin, as well as those who quickly get suntanned, bear less risk of getting cancer than people with pale skinn , prone to sunburns. However, even if this fact is correct, the experts will again not recommend exposure to UV rays as a preventive of this malignant disease.
Every exposure to UV rays makes a biological change on your skin that further leads to the risk of cancer.
Are UV rays represent a different threat for various people?
Sunburns are particularly associated with risen skin cancer risk. Perhaps, if it could be possible to get a tanned skin without burning if that means the protective effects of the tanning could overweight the risk of ultraviolet (UV) radiation to get the tan in the first place?
Theoretically, yes. But the main question is still on – is it the sunburn or is it the UV exposure that is crucial for skin cancer risk? Recent data suggests it’s all about the UV dose you build up over time, not just getting sunburnt. Most sunburn does not indicate a high UV exposure, but avoiding it is not enough to protect you. It is even possible to avoid it for all your life and ultimately end up with skin cancer associated with UV exposure.
What tanning is precisely doing for our skin?
The process of tanning is an adaptive answer to the stress your skin suffers while being exposed to more sunlight than it can handle. This way, it is protecting itself against UV that can harm DNA in the skin cells, possibly causing skin cancer.
When exposed to UV rays, skin cells produce melanin, a pigment whose role is to protect the DNA. In that sense, we can say that gradual tanning can represent a ‘shield’ from those harmful rays. Besides, pale people who will be exposed to the sun, get sunburns, peel the skin, then be again expose to UV treatments are more vulnerable.
If you avoid sunburn by getting tanned skin tone in more portions of short intervals, to practice so-called ‘smart sunbathing’ or simply, you have a darker skin that is not prone to burns, then you belong to those people whose skin is protecting itself to getting tanned skin tone. This protection can be expertly evaluated at SPF 3 or 4, while the average sunburn protection will give you the SPF 30 factor.
Artificial tanned skin tones obtained by using sprays or creams do not represent any protection against UV rays, and while on the skin, it is necessary to use another protection.
People who are practicing sunbathing usually doing it to get a more attractive body, or to cover defects such as stains on the skin, wrinkles, lines. What everyone has to know, tanned tones will temporarily camouflage the flaws, but tanning have precisely the same unwanted effects on the skin on a long run. Wrinkles, fine lines, and stains. About 80% of facial skin aging is associated with excessive sun exposure.
However, as aesthetics are not a subject here, we will return to the protective role of tanning. The conclusion is – there are a lot of smarter ways to protect your skin from UV rays. Avoid the sun or consume it at short intervals sufficient to absorb the required amount of vitamin D. Use sunscreen, hats, fabrics. Sometimes it’s hard to estimate when it is enough tanning, that can put you at enormous risk.
