Every person needs exposure to the sun, it's the primary source for a human to get vitamin D which will help us accumulate calcium for strong and healthy bones. However, you don't have to stay in the sun for hours and hours each day to collect the Vitamin D you need. If people stay outside in the sun for longer times whilst being unprotected, people could develop drastic issues with your health, the ultraviolet rays that the sun emits could cause skin and eye damage, a weaker immune system, and even skin cancer, A person of ANY age is affected by this, so make sure to look after your kids well! 
 

50 - 80% on average is the total amount of sun exposure a child will accumulate before the age of 18! It is drastically important that parents will teach their children how to protect themselves in the sun, as nobody wants to damage their children, and want to leave them to develop skin cancer at such an age.
 

Facts About Sun Exposure
 

The Sun emits light to earth, and the light comes in many different rays, Ultraviolet rays are invisible, and deadly. When UV rays reach your skin they will cause it to tan, burn, and possibly give skin cancer.
 

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

UVA rays cause skin aging and wrinkling and contribute to skin cancer, such as melanoma. Because UVA rays pass effortlessly through the ozone layer (the protective layer of atmosphere, or shield, surrounding the earth), they make up the majority of our sun exposure. Beware of tanning beds because they use UVA rays as well as UVB rays. A UVA tan does not help protect the skin from further sun damage; it merely produces colour and a false sense of protection from the sun.
 

UVB rays are also dangerous, causing sunburns, cataracts (clouding of the eye lens), and effects on the immune system. They also contribute to skin cancer. Melanoma, the most dangerous form of skin cancer, is thought to be associated with severe UVB sunburns that occur before the age of 20. Most UVB rays are absorbed by the ozone layer, but enough of these rays pass through to cause serious damage.
 

UVC rays are the most dangerous, but fortunately, these rays are blocked by the ozone layer and don't reach the earth.
 

What's important is to protect your family from exposure to UVA and UVB, the rays that cause skin damage.
