Health Tip: Heat Cramps Shouldn't Be Ignored

Heat cramps occur in people who are exerting themselves during periods of significant heat and humidity. They shouldn't be ignored, because heat cramps can be the first signs of more serious conditions, including heat exhaustion or heat stroke.

The American Red Cross suggests these steps if you get heat cramps or additional warning signs of heat-related illness:

* If you have heat cramps or more serious symptoms of heat-related illness, immediately stop all activity and rest. Go to an air-conditioned or shady place, if possible.
* Symptoms of more serious heat-related illness include: moist, pale skin; headache, dizziness, weakness, exhaustion or nausea.
* Drink cool water or a sports drink slowly and in small amounts.
* Stretch the cramped muscles, and hold the stretched position for about 20 seconds. Repeat the stretching until the cramps have stopped.
* If symptoms persist, seek immediate medical attention. Resume activity only if you no longer have any symptoms. But be very careful of overexertion and overheating.

Health Tip: Treating a Blister

Blisters are sore, swollen areas on the skin where fluid has collected beneath an outer layer of skin. Blisters are caused by friction, often from poorly fitted shoes or socks that rub against the skin.

Here are suggestions on caring for a blister, courtesy of the University of Michigan Health System:

* Steps should be taken to avoid further irritating the problem area.
* Large blisters can be carefully drained with a sterilized needle, then covered with antibiotic ointment and a bandage.
* For extra protection, purchase a moleskin at a drugstore. Cut a hole that's larger than the blister in the moleskin, creating a moleskin "donut." Then apply the moleskin so that the hole is over the blister.
* See your doctor about any blisters that don't heal in a reasonable amount of time, or look like they may be infected.
