Q. Can being in a pool, taking a cool bath, or showering help prevent dehydration?

A. Dehydration occurs when there is not enough water in your system to nourish your cells and vital organs. It is true that some water is absorbed into your skin if you are in water for a sustained period of time, but little if any ends up in your central circulation. Being in cool water, however, may help prevent another danger of extreme high temperatures: heat-related illness. Heat cramps, heat exhaustion, and the life-threatening heatstroke all occur when your body stops being able to cool itself. Cooling your skin externally helps lower your body’s internal temperature. It is still vitally important that you drink plenty of liquids, even if you are not exerting yourself. You can still be dehydrated if your body is surrounded by water. 

Q. I have a brown patch inside my mouth called an oral melanotic macule. Can it turn into cancer?

A. An oral melanocytic macule is a benign pigmented area of the mouth—usually located on the lips but it also occurs on the gums, insides of cheeks, or roof of the mouth. These lesions tend to be less than one-third of an inch in size and require no treatment unless it bothers you. They do not tend to grow bigger or change shape, and some go away or fade on their own. Research shows that oral melanocytic macules do not change into cancerous lesions.
