It What ways does sunlight affect the human skin?

The effect of sunlight is more dangerous than most people think. Skin cancer is an obvious disease that is a direct affect of the sun





This has led to extensive efforts to raise awareness of the risks involved in overexposure to the sun and of the behavioral changes needed to avoid it. Melanoma is one type of cancer that can strike people of any age, race, gender, and economic status





sunburn develops when the amount of UV exposure is greater than what can be protected against by the skin's melanin. The lighter your skin, the less melanin it has to absorb UV and protect itself. And all skin, no matter what color, responds to continued sun exposure by thickening and hardening, resulting in leathery skin and wrinkles later in life.





Unprotected sun exposure is even more dangerous if you have moles on your skin, very fair skin and hair, or a family history of skin cancer, including melanoma. You should be especially careful about sun protection if you have one or more of these high-risk characteristics.





Not all sunlight is "equal" in UV concentration. The intensity of the sun's rays depends upon the time of year, as well as the altitude and latitude of your location.





UV rays are strongest during summer. Remember that the timing of this season varies by location; if you travel to a foreign country during its summer season, you'll need to pack the strongest sun protection you can find
