John's Tips: Fun In The Sun
Monday, Jun 21, 2010
If you plan to exercise in the sun, you should not wear cotton t-shirts. Find clothing made of fabrics that wick away sweat, ventilate the body, and block the sun. Cotton t-shirts have an SPF of only 5, yet there are sun-blocking fabrics that offer up to SPF 30 due their microfiber fabric construction. Sunburned pores are much less efficient at releasing sweat to cool the skin. If you are sunburned, your skin will not thermoregulate very well and you should reduce your exercise intensity. So, have fun in the sun, but take a few simple steps to protect yourself from the potential danger of overheating.
