Heat-related illnesses are the most serious complications of anhidrosis. Children are especially vulnerable because their core temperatures rise faster than adults', and their bodies release heat less efficiently.

Heat-related problems include:

  • Heat cramps. These muscle spasms, which can tighten muscles in your legs, arms, abdomen and back, are generally more painful and prolonged than are typical nighttime leg cramps.
  • Heat exhaustion. Signs and symptoms such as weakness, nausea and a rapid heartbeat usually begin after strenuous exercise. Monitor someone with heat exhaustion because symptoms can quickly become worse.
  • Heatstroke. This life-threatening condition occurs when your body temperature reaches 104 F (40 C) or higher. If not treated immediately, heatstroke can cause hallucinations, loss of consciousness, coma and even death.
