Effects of the sun
The good effects:The sun provides us with life – the gifts of light and warmth that all animals and plants need to live and grow.
Effect of the sun
The bad effects: The sun can present us with danger as well. Many of us do not understand the hidden dangers of the Sun’s ray and are unknowingly putting our health at risk by prolonged exposure to the sun.
Factors raise a person’s risk of getting melanoma (1)
Hereditary factors are factors you are born with, your general genetic make up, things like your skin and hair color. Dark-skinned Asians and Hispanics are 50 times less likely than light-skinned and light-eyed people of northern European and especially those with blond or red hair are at risk.

Environmental factor also influence your chances of contracting the disease, geography is associated with the incidence of skin cancer. The farther north or south of the equator you are, the less likely you are to get skin cancer because the sun’s ray are not directly overhead, but instead hit the Earth at a softer angle.


Factors raise a person’s risk of getting melanoma (3)
Behavioral factor is the history of the person, the amount of exposure to the sun that the person has had from birth on. We can say that it’s quite clear that getting sunburned frequently and severely early in our lives can have negative consequences later on. This means that parents, especially, are educated about the dangers of this problem so that they can try to keep their children protected. It also means that certain kinds of jobs-outdoor jobs-will put a person at greater risk.
How to protect ourselves from the sun

Apply lots of sunscreens (1)
Use sunscreen on all exposed skin. Your sunscreen should have a sun protection factor (SPF) of at least 15. your sunscreen should protect you from both ultraviolet A (UVA) and ultraviolet B (UVB) rays.

Also, apply it under bathing suit straps, necklaces, bracelets, and sunglasses.
You should put on one ounce of sunscreen every two hours-one ounce is about the size of a ping pong ball.

Wear sunglasses

Wearing sunglasses protects your eyes from harmful UV rays when outdoors.
Choose sunglasses with 99 to 100 percent UVA and UVB protection, to block both forms of ultraviolet rays.
Be careful near water, snow, and sand
Water, snow, and sand can reflect the damaging rays of the sun and increase your chance of sunburn.
Sit in the shade
Remember that the sun’s UV rays are strongest between 10 a.m and 4 p.m. try to stay in the shade if you are outside during these times.
Get Vitamin D safely.
Vitamin D is an important vitamin that our bodies make when we are out in the sun. But there are other ways to get vitamin D without being in the sun. You can get vitamin D through fortified milk and orange juice, cheese, butter, cereals, and fish. You can also get vitamin D through vitamin supplements.
