Does exposure to sun causes skin cancer? Read on to know about this.
There is no proof that exposure to sun leads to skin cancer. In fact, few people can get skin cancer in the areas that are not even exposed to sun.
A study revealed that UV-B does not cause cancer but UV-A does. Normally, if you expose your skin to the sun for a longer period, then your skin may start burning. In order to get rid of this, you will apply sunscreens. But do you know, most skin lotions contain UV-A, whereas, few lotions does not contain both UV-A and UV-B. By applying such type of skin lotions, you will be deficit of vitamin D. Deficiency of vitamin D can lead to cancer.
Sunscreens are made up of abundant chemicals that can easily penetrate into the blood. These chemicals end-up going to the liver and some tissues present beneath the skin layer. So, this might result in developing skin cancer. Hence, sunscreens are now a leading cause of skin cancer.
Another important thing to consider is washing your body with soap, which might wash off vitamin D that has been accumulated on your skin. If you are exposed to sun, you can get vitamin D by not washing your body with soap except on the areas that are not exposed to sun. The vitamin D can be absorbed by the skin for up to 48 hours. So, it is better to avoid soap to retain bacteria that helps in skin nourishment.
