Persuasive Speech On Sun Protection

Part of the sun’s energy that reaches us on earth is the rays of invisible ultraviolet (UV) light. When UV light rays enter the skin, they damage the skin cells, causing injuries that can be visible like sunburns, or invisible. Some of the injury is fixed, but some of the damage adds up year after year. After a long time, the built-up damage appears as wrinkles, age spots, and even skin cancer. Also, freckles, which occur in people with fair skin, are usually due to sun exposure. Freckles are nearly always a sign that sun damage has occurred, and show the need for sun protection. A sunburn is damage that you can see. If you get burned, be sure to rub aloe over the burn and cover up! Sun exposure can harm ANYONE at ANY AGE. Sun protection should begin in infancy and continue throughout life. It is estimated that we get about 80 percent of our total lifetime sun exposure in the first 18 years of life. Therefore, sun prevention in childhood is very important
So be sure to wear sunscreen to protect yourself. But… what exactly are you protecting yourself against?
C. Ultraviolet (UV) Radiation
There are many different types of radiation. For example, visible light is everything you see; all the colors that are you are able to see. One step above visible light is ultraviolet radiation. There are 3 major types of ultraviolet radiation: UVA, UVB and UVC. The atmosphere usually absorbs UVC before it reaches the Earth. The ozone layer serves as a natural shield to many of the sun’s rays, however, now that the ozone layer is slowly depleting, more and more UV radiation can get through. UVB partially reaches the Earth, and UVA completely reaches the Earth. What does UV Index mean?
The ultraviolet index or UV Index is an international standard measurement of the strength of ultraviolet (UV) radiation from the sun at a particular place and time. Remind them that this number is always used by meteorologists in their weather
