Some people perspire profusely just walking to the mailbox, while others can run for miles without breaking a sweat. Many people make the mistake of relating sweat to hard work and a loss of calories, but everyone has different sweating patterns. Although many people would rather stay dry, a lack of perspiration could indicate a serious medical condition. If you're worried, discuss your sweating patterns with your doctor.
Your body is constantly producing heat. The heat radiates out through the skin most of the time. However, when your body is working hard, contracting muscles as you exercise, some of the heat is absorbed by the water in your blood, which then rises to the surface of the skin through sweat glands. It then evaporates and creates a cooling effect.
Everyone doesn’t sweat the same. Women tend to sweat less than men and usually require higher temperatures than what would cause men to sweat. Women also sweat less as they grow older because their sweat glands shrink and are less sensitive, according to the "Daily Mail Online." Fitness level and environmental factors can also contribute to the amount you sweat.
Perspiration is not an indicator of a losing weight. “You don’t have to sweat to get a good workout, and exercising in higher temperatures and humidity can be dangerous,” Gerald Endress, an exercise physiologist and fitness director at the Duke University Diet and Fitness Center told MSNBC. Many people wear lots of layers hoping to sweat off the pounds, but that doesn’t mean they are losing fat any faster. It means they are sweating more and, the more you sweat, the more water you need to take in to stay hydrated. Keeping clothes on because you think it’s better to sweat makes you uncomfortable and puts you at risk of dangerously overheating.
Anhidrosis, also called hypohidrosis, is an absence of sweating. Those who wish they could avoid the gross factor linked to sweating might consider anhidrosis a plus, but not being able to perspire could be uncomfortable and potentially life-threatening. Sweat acts as your body’s coolant and, without it, the body can suffer from heat-related illnesses like heat exhaustion and heatstroke. Anhidrosis can be caused by certain drugs or medications, nerve damage, clogged sweat ducts, skin injuries or may be an inherited condition. If you feel you might be suffering from anhidrosis, speak with your doctor.
