Sweating is the release of water and dissolved salts through the pores of the skin for thermoregulation. It can be caused by physical activity, hormonal imbalances, medical conditions, and psychological stress. Excessive sweating, known as hyperhidrosis, can be embarrassing.
Sweating, also known as perspiration, is a process in which many organisms, including humans, release water and dissolved salts through the pores of the skin. The main purpose of this process is thermoregulation, or temperature control; an organism tends to sweat when it overheats. Most causes of sweating are related to the body returning to a normal, healthy temperature. Many organisms tend to sweat when they engage in some form of vigorous activity, such as strenuous exercise. However, there are many other things that can cause sweating; some are related to medical ailments while others may simply be related to stress or emotional strain.
Vigorous physical activity is among the most common causes of sweating. When you sweat, the sweat coats your skin; this perspiration then evaporates and takes part of the body heat with it. When one engages in particularly hard exercise, his body produces more heat. Consequently, the amount you sweat corresponds to the rigorousness of the activity you are performing.
The causes of sweating also tend to be closely related to the balance of hormones in the body; conditions or substances that alter hormone levels can cause sweating. People suffering from cancer or certain infections sometimes sweat due to the effect these diseases have on the balance of hormones. Fever is also among the many causes of sweating, but this is more closely related to an increase in body temperature than to hormonal balance. There are certain substances that many people ingest on a regular basis that can cause sweating. Caffeine and alcohol are two of the most prominent examples, although many drugs can have similar effects.
There are also some psychological causes of sweating. People often sweat when they’re scared, nervous, or under significant stress. This is also related to hormones; When under emotional stress, the adrenal gland produces more than normal amounts of the hormone epinephrine. This, combined with other altered hormone levels, can lead to sweating. Often, sweating in response to psychological stress feels cold because it doesn’t occur in response to physical heat.
Some people sweat excessively almost all the time. Such excessive sweating is known as diaphoresis or hyperhidrosis and often has no clear cause. Usually, this form of sweating is concentrated in the palms and armpits. Because he can smell and soak clothes, this can often be an embarrassing condition.
