Our skin regulates body temperature by sweating. Although we are not aware of it, this sophisticated natural mechanism keeps us alive, because the body requires a constant internal temperature. But some people do not sweat enough, and, in some cases, this disorder has serious repercussions.
This blog has already included a post on the bothersome problem of excessive sweating (hyperhidrosis) and its treatments. But sweating too little (hypohidrosis) or not sweating at all (anhidrosis) are much more dangerous to health, because the body fails to maintain its proper temperature. The pores of the skin, usually easily seen under a magnifying glass, are virtually invisible in people with these problems. The causes, whether genetic, endocrinological (diabetes, hypothyroidism) or neurological, affect the nerves involved in sweating. Symptoms include dizziness, headache, nausea, trembling, fever and tachycardia. These syndromes have no cure or medication, but fortunately affect few people. The only solution is to hydrate properly and avoid heat stroke by staying in the shade.
