Unprotected sun exposure can affect your skin in many ways. It can deplete collagen, make the skin sag and promote aging. But do you know it can give you skin cancer too? Let’s discuss.
You must have heard countless times how essential sunscreen is for you to prevent sunburns and premature aging. But you should also know that the scariest thing unprotected sun exposure does, it gives you skin cancer. And it is not related to high temperatures or very bright sunny days. This damage can occur on low temperatures even on cloudy days too.
Two types of UV rays reach the earth:
UVA: Penetrates deep into the skin and promotes aging.
UVB: Does not penetrate deeper but causes sunburns.
The third type of UV rays, called UVC rays, could be more damaging, but fortunately they are blocked by the ozone layer.
These UV rays enter the skin cells and damage our DNA. This DNA controls a cell. Damaging DNA can initiate abnormal growth of cells leading to a tumor that can be benign or malignant. Getting sunburn once every two years increases the chances of developing skin cancer by three times. And all you need to avoid this scary disease is a small amount of sunscreen.
