Water is one of the most essential components of the human body. Water not only composes 75 percent of all muscle tissue and about 10 percent of fatty tissue, it also acts within each cell to transport nutrients and dispel waste. And, because water composes more than half of the human body, it is impossible to sustain life for more than a week without it.
Necessary to the healthy function of all internal organs, water must be consumed to replace the amount lost each day during basic activities. It is recommended that women consume 91 oz. daily and men consume 125 oz. through various beverages (80%) or in food (20%).
Active individuals need even more, particularly if they’re exercising in hot weather. Without an adequate supply of water the body will lack energy and muscles may develop cramps. To prevent dehydration, exercisers must drink before, during, and after the workout.

According to the latest study by the Environmental Working Group’s – 2014 Sunscreen Guide, all sunscreens are not created equal. In fact, many contain potentially harmful ingredients. The two chemicals that may put the user at risk are: Oxybenzone, which penetrates the skin and may disrupt the hormonal system and cause allergic reactions. 40% of all sunscreens contain Oxybenzone. The other is Retinyl Palmitate (Vitamin A) which may promote the development of skin tumors in sun exposed skin. 20% of all sunscreens contain this Vitamin A.
Sunscreens that appear to be safer for the consumer include zinc and titanium-based products that do not penetrate the skin. The zinc that originally came only in pure white is now available in “clear” formula. Additionally, how you apply sunscreen matters. The recommended application is every two hours. For even more protection from dangerous rays, wear “physical sunscreens” such as a big hat, sunglasses, and a long-sleeved shirt.
