We've all heard the phrase “a healthy tan”, but there's no such thing. Tanning is the body's attempt to protect itself from the harm caused by ultraviolet (UV) radiation. The UV radiation that reaches the Earth's surface is mainly UVA and part of UVB. Nearly half of the most dangerous UVB radiation during the day is received between 10 in the morning and 4 in the afternoon.
Even on a cloudy day, UVB radiation can cause sunburn. The National Weather Services' UV index predicts the next day's UV radiation levels on a scale of 1 to 11 or higher. This information helps people plan how to protect themselves from the sun. Everyone needs some exposure to the sun to produce vitamin D (which helps absorb calcium for stronger, healthier bones).
However, unprotected exposure to the sun's ultraviolet (UV) rays can damage the skin, eyes, and immune system. UVB rays cause a much higher risk of skin cancer than UVA rays. Ultraviolet radiation from the sun is the main cause of skin cancer, but UV light from tanning beds is just as damaging. There are other contributing factors, such as heredity and environment.
However, sunburn and excessive exposure to UV light do damage the skin. This damage can result in skin cancer or premature skin aging (photoaging). It is essential to be aware of your exposure to UV light. The National Foundation for Environmental Education (NEEF) SunWise program provides resources and information related to sun protection and safety measures.
The website also provides maps of current and expected UV levels in the United States. To protect yourself from UV light, you should wear protective clothing, sunglasses, and sunscreen with an SPF of at least 15 when outdoors. You should also limit your time in direct sunlight, especially during peak hours when UV radiation is strongest. It is important to be aware of your exposure to UV light. Taking steps to protect yourself from excessive exposure can help reduce your risk of skin cancer and other health problems.
It is essential to understand how much UV light is dangerous for your health and how you can protect yourself from it.
