Sweat a lot, don’t sweat

We often think that, not sweating means that the body is not having any problems. But the reality is quite the opposite. No sweat is a concern. Sweat is released to regulate body temperature and keep the body from overheating. This is a normal function of the body with necessary benefits.

Hyperthyroidism – the medical term for an overactive thyroid that can be the culprit behind your frequent sweating. According to the University of Pennsylvania Health System: “Hyperthyroidism can cause extreme heat sensitivity and sweating, making it difficult for people with hypothyroidism to stay warm.“. (Hypothyroidism is the term for an underactive thyroid gland.)

When the body’s thyroid gland is functioning properly, its cells produce 65% of energy and 35% of heat. However, people with hypothyroidism produce either too much or not enough of the hormone thyroxine. This hormonal change can alter the body’s sweat production, causing excess heat and reduced energy, or vice versa.“, the agency said.

Other symptoms of hyperthyroidism can include fatigue, weight changes, and swelling in the neck where the thyroid is located.

Nervous system malfunction

Never breaking a sweat sounds like fun, but in reality, it can be very harmful. “Sweating helps remove heat from the body, helping the body cool down“, according to the Cleveland Clinic.”If you can’t sweat, your body is overheating, which can be dangerous and even life-threatening.“.

Some people are born with anhidrosis, a condition in which the body doesn’t sweat as it should. However, it can also be a symptom of a medical condition affecting the nervous system.

Excessive sweating can be a sign of diabetes. Research shows that up to 84% of people with diabetes sweat when they have low blood sugar, most commonly the back of their neck. During hypoglycemia, the body produces the hormone adrenaline in response to a drop in blood sugar, which leads to narrowing of blood vessels and activation of sweat glands.

In addition to sudden, heavy sweating, other symptoms of diabetes can include frequent urination, unexplained weight loss, numbness or tingling of the hands and feet, and extreme thirst.

It’s not clear why certain types of cancer cause night sweats. Sweating can be caused by hormone changes, a fever, or the body’s attempt to fight cancer.
