Sun and Skin Care

HERE COMES THE SUN: The sun emits three forms of light: infrared (heat), visible light, and ultraviolet (UV) light. It is the latter that is responsible for skin damage. Prolonged exposure can damage and kill skin cells, which then release chemicals that activate the body’s pain receptors. The reddening of sunburned skin is the result of increased blood flow to the damaged areas in order to remove the dead cells.

HOW IT WORKS: UV light causes chemical changes in the body that can suppress the body’s immune system and stimulate the growth of cancer cells by generating toxic substances known as free radicals. These substances, which attack and damage our DNA, are believed to be one of the factors that cause skin cancer. MSM has been proven to be a "biological scavenger" in that it changes free radicals back to a less harmful configuration.

ABOUT THE UV INDEX: The UV index is a standard measure of the amount of UV radiation striking the Earth’s surface, and the most accurate measure of sun exposure risk. In the US, the UV index starts to increase in March and April, peaking every year in June. The ozone layer in the Earth’s upper stratosphere absorbs most of the sun’s UV radiation, but ongoing damage to that protective layer means that UV-related health risks continue to increase. NASA solar experts report that this year was the strongest and most active sun activity cycle in nearly 50 years, a state they expect to persist for the next 7-10 years. As a result, people will need more UV protection than ever before over the next decade. The farther South one goes the stronger the UV rays become due to angle refraction through the Ozone layer.
