Certain factors make anhidrosis more likely, including:

  • Age. People age 65 and older, infants, and children are more prone to heat stress, which can contribute to anhidrosis.
  • Certain health problems. Any medical condition that damages your autonomic nerves, such as diabetes, makes sweat gland problems more likely.
  • Skin disorders. Many diseases that irritate or inflame the skin also affect the sweat glands. They include psoriasis; exfoliative dermatitis, which is marked by severe skin scaling; heat rash; scleroderma, which causes hard, tight skin; and ichthyosis — extremely dry, scaly skin.
  • Genetic abnormalities. Mutations in certain genes can lead to disorders that affect the sweat glands.
