Night sweats, also called nocturnal hyperhidrosis, can be a very uncomfortable experience for men.

The evaporation of sweating from the skin’s surface cools the body to maintain a normal body temperature. Nerves of the sympathetic nervous system control the output of sweat glands to regulate how much sweat they produce. Eccrine glands, found all over the body including the armpits, secrete a watery, cooling sweat.

Mayo Clinic experts state that excessive sweating (hyperhidrosis) occurs when the sweat glands produce more perspiration than necessary to cool the body. In some cases, this may be the side-effect of taking certain medications. But there are also specific medical conditions that can cause excessive sweating.

Excessive back sweat could be a sign of hyperhidrosis, a condition marked by overactive sweat glands. A sweaty back is usually a sign of generalized hyperhidrosis, notes MayoClinic.

Excessive sweating -- a condition known as hyperhidrosis -- can be an embarrassing and irritating problem, especially in visible areas such as the forehead. According to Hyperhidrosisweb.com, the condition occurs in an estimated 3 percent of people worldwide.

Anyone can develop excessive sweating during a workout, no matter their fitness level. Excessive sweating during exercising does not mean that you are out of shape -- in fact it can sometimes signal the contrary.

If you sweat excessively during a workout, you can become dehydrated. According to MayoClinic.com, one of the symptoms of dehydration is thick, stringy saliva, which can form a white, sticky substance around your mouth. Another cause is a condition known as dry mouth.

Excessive sweating, also known as hyperhidrosis, affects 2 to 3 percent of the population; however, less than 40 percent seek medical help, according to Medline Plus. Excessive sweating affects the armpits, feet, hands, groin region and head.

Night sweats, known medically as nocturnal hyperhidrosis, is a condition in which an individual has perspiration during the night hours.The sweating may be profuse, leaving sheets and clothing wet. It may occur in someone who does not excessively sweat during the day.

Sweating from things like exertion or overheating affects your serum magnesium and other electrolyte levels. If you experience excessive sweating, you are at increased risk for a low magnesium level, or hypomagnesemia. A low magnesium level causes several unpleasant symptoms, some of them dangerous.

In most cases, sweating is not a reason you should be concerned about your toddler. When you sweat, perspiration is released from your pores to keep the body cool during periods of stress such as exercise and heat exposure.

The primary function of perspiration is to cool the body when it overheats. Overheating can occur due to high ambient temperature or rising internal temperature (from muscle stimulation). Emotional stimuli and certain foods (such as hot and/or spicy foods) can also cause sweating.
