What is hyperhidrosis, what are its symptoms and why it manifests with high temperatures
We can summarize hyperhidrosis as a noticeable increase in sweating in certain areas of the body. The Clinic of the University of Navarre reports that this is the result of an increase in the secretion of the sweat glands.
This increase in sweating is usually due to a hyperactivity of these glands by a nervous hyperstimulation, motivated by situations involving emotional tension or stress, by the action of pharmacological substances or for thermal reasons. These thermal reasons are what cause that with the excess of heat, the high temperatures also cause a greater number of sweating and, therefore, hyperhidrosis.
The sweat glands of the palms of the hands, the soles of the feet, the armpits and the craniofacial region are especially sensitive to emotional or thermal stimuli, producing a more intense sweating to regulate the temperature and counteract the rise in temperature. In addition, the Clinic of the University of Navarre reports that hyperhidrosis can cause work and social disability. This affects about 1% of the population, in which almost half of the cases are hereditary.
The causes of hyperhidrosis are usually mainly thermal and emotional stimuli. These stimuli trigger the cholinergic response of the sweat glands causing this excess sweating, according to the Clinic of the University of Navarre.
The factors that cause stress in the person can be public speaking, fear of being observed, to remain in the company of other people, fear of various situations and, even, to blush itself. Hyperhidrosis may also be caused by some pharmacological treatments.
