Why does your body tan?

Answer 1

Tanning begins as soon as you step out into the sun. UV rays hit your skin and start to break down the DNA in your. In order for the body to protect itself to prevent further damage to your body, it starts to produce melanin. The more melanin in your body, the darker the body becomes and the more protected you are from the sun. So someone who has spent a lot of time in the sun can stand out in the sun for longer periods of time without the risk of sunburn. A suntan needs to be gradual, so it is better to tan for only a little bit at a time and with the right sort of protection like using sunscreen.

Answer 2

The melanin reacts with prolonged sun exposure
The process is most often a result of exposure to ultraviolet (UV) radiation from the sun or from artificial sources, such as a tanning bed.

Answer 3

Basically a reaction to UV rays. The UV rays stimulate melanocytes to produce melanin, which absorb the rays. This absorption protects the skin from the sun, also creating the pigment change called a tan.

Answer 4

The sun makes your skin produce more melanin, the stuff that gives your skin color. That's how you get freckles or darker skin. It is important to realize that when this happens - it is because your skin is being damaged and a layer of cells is being stimulated to create Melanin for protection.

Tanning is a response to that - but it doesn't prevent the damage.

Answer 5
