Treatments and drugs
By Mayo Clinic staffAnhidrosis that affects a small part of your body usually isn't a problem and doesn't need treatment. Large areas of decreased perspiration, however, can be life-threatening. Anhidrosis treatment usually focuses on the cause of the problem rather than on anhidrosis specifically.
Treating heat-related problems
Anyone who is overheated needs prompt treatment to prevent symptoms from becoming worse.
Heat cramps
To relieve cramping:
- Rest and cool down
- Drink cool fruit juice or a sports drink that contains electrolytes
- Gently massage tight muscles
- Get medical care if cramps become worse or don't go away in about an hour
Heat exhaustion
When someone develops symptoms of heat exhaustion, such as nausea, dizziness and a rapid heartbeat, act quickly.
- Move the person into a shady or air-conditioned space, and elevate his or her legs slightly.
- Loosen the person's clothing.
- Have the person drink cool, not ice, water or a sports drink that contains electrolytes.
- Spray or sponge the person with cool water.
- If symptoms don't improve quickly, call 911.
Heatstroke
Heatstroke requires immediate medical care. Until help arrives:
- Move the person into the shade or an air-conditioned space.
- Start the cooling process by spraying the skin with water or wrapping the person in wet towels or sheets, and use a fan or newspaper to increase air circulation.
- If possible, place ice packs on the groin, neck and head.
