How Does Exposure to Sun Affect Your Child?

All of us need to be exposed to sun. Sun is our primary source of vitamin D. Due to this, we are able to absorb calcium for stronger and healthier bones. It does not take time for most people to get the vitamin D they need from the sun. However, you just remember that unprotected exposure to the ultraviolet rays of sun can cause damage to skin, eyes and can also lead to immune system suppression or cancer. In 50% to 80% of a child’s lifetime before they turn 18, he/she remains exposed to sun. It is important for parents to teach their children how to take care of themselves while exposed to sun. With some precautions, you can reduce your child’s prospects of developing skin cancer.

There are a lot of facts about sun exposure. The sun radiates light to the earth and some part of that light has ultraviolet (UV) rays. When UV rays reach the skin, it causes tanning, burning, and other skin damage.

The UVA, UVB and UVC rays

Sunlight has three types of ultraviolet rays and these include UVA, UVB and UVC.

UVA ray leads to skin aging and wrinkling. These rays also contribute to skin cancer. These include melanoma. UVA rays pass through the ozone layer and reach the earth. You must also take caution in treating skin tan. A UVA tan will not help you in protecting your skin from sun damage. UVB rays are threatening to skin too. It can lead to sunburns, cataracts and immune system damage. These rays can also lead to skin cancer. UVC rays are the most dangerous among all the rays. However, these rays do not reach the earth as they are blocked by the ozone layer.

What are the harmful effects of too much sun exposure?
It is more crucial to protect your family from exposure to UVA and UVB. These rays can pose threat to your skin and can actually damage your skin. UV rays present react with melanin. Melanin is an active defense against the sun, since melanin absorbs UV rays before they can hamper your skin. Melanin causes color of the skin. Individuals having fair complexions are more likely to get freckles. When melanin increases in response to sun exposure, the skin begins to tan. The more you expose your skin to sun, the more damage is caused. Individuals who are chronically exposed to the sun like farmers and boaters have a higher risk of sun exposure. If you are staying near equator, extra protection will be required since sun is strongest at high altitudes and more UV rays pass on to earth. During winters, be sure to apply sunscreen lotion. This can reduce the sun burns.

You should avoid being in the sun between 10 a.m and 4 p.m since that is the time when the sun is at peak.
