Sunburn can also be caused on a cloudy or cool day. Because snow, water, and sand can reflect UV rays and can cause severe damage as severely as direct sunlight.

The UV radiation is referred to as the wavelength of sunlight and is in too short range to be visible by a human eye.

Ultraviolet A is associated with skin aging, and Ultraviolet B is associated with sunburn. Both types of UV’s can be dangerous and may lead to cancer.

Some of the artificial lights like tanning beds and sunlamps can cause sunburn as they also produce UV light.

So, why does the body Tan occur?

There is a pigment in the outer layer of the skin which gives the body its normal color; this pigment is called Melanin. When the skin is exposed to the UV light, there is a sudden increase in the production of Melanin to protect the skin. This extra melanin leads to skin tan.

But some people don’t produce enough melanin to protect the skin which ultimately leads to sunburn-causing redness and pain.
