Treatments and drugsBy Mayo Clinic staff
Treatment isn't always necessary
Anhidrosis that affects a small part of your body usually isn't a problem and doesn't need treatment. But large areas of decreased perspiration can be life-threatening. Treatments may be available for the condition that's causing the anhidrosis.
Treating heat-related problems
Overheating needs prompt treatment to prevent symptoms from becoming worse.
To relieve cramping:
- Rest and cool down.
- Drink cool fruit juice or a sports drink that contains electrolytes.
- Get medical care if cramps become worse or don't go away in about an hour.
- Wait at least several hours before returning to strenuous activity.
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, and remove any heavy pieces of clothing.
- Have the person drink cool, not iced, water or a sports drink that contains electrolytes.
- Spray or sponge the person with cool water.
- If symptoms don't improve quickly, call 911 or emergency medical help.
Heatstroke requires immediate medical care. This condition can be fatal if left untreated. 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.
