Learn everything about sweating (also known as perspiration)! Here you will find the most frequent questions and answers about abnormal sweating that are important to know.
What is sweat?
Sweat is a fluid composed almost entirely of water, along with traces of other substances such as salt and ammonia, which is secreted by sweat glands located all over the body.
What types of sweat glands do we have?
There are two types of sweat glands: apocrine and eccrine glands. They are located in different regions of the body and secrete different types of sweat.
What are the main characteristics of sweat glands?
Eccrine glands secrete a clear, odorless fluid that plays a role in regulating body temperature. Apocrine glands are found around hair follicles and secrete a different type of fluid related to body odor.
What characterizes apocrine sweat?
Apocrine sweat is secreted by apocrine glands in hair follicle-rich areas such as the scalp, underarms, and groin. Apocrine glands open into hair follicles and lead to the skin surface. They secrete thick, oily sweat responsible for body odor.
What characterizes eccrine sweat?
Eccrine glands are found all over the body surface, most densely on the palms, soles, and forehead. Eccrine sweat is essentially an odorless, diluted saltwater. These sweat glands are responsible for regulating body temperature.
What triggers sweating?
Common causes of sweating include physical activity, stress, high temperature, illness, and eating.
Why do we sweat?
The body regulates temperature through sweating, keeping cool and comfortable, preventing overheating.
How does sweating cool the body?
The process is called evaporative cooling. When sweat reaches the skin's surface, it evaporates, cooling the body.
Why is sweating important?
It is a very important bodily function that regulates body temperature and prevents overheating! People who do not sweat (anhidrosis / hypohidrosis) are at risk of serious, life-threatening complications like heatstroke.
How is sweating activated?
When the body begins to warm, the nervous system activates eccrine sweat glands throughout the body, which secrete sweat (clear, odorless fluid) to cool down. As sweat reaches the skin surface, it evaporates and creates a cooling effect.
Why do I sweat when I eat?
Certain foods can activate sweat glands or increase sweating. Coffee and alcohol can cause this.
The body works hard to convert heavy foods into energy. The harder it is to digest a food, the more it can cause sweating.
Overly hot, spicy, or heavily seasoned foods can also trigger sweating during meals.
If you constantly sweat while eating (or even just thinking about food), consider a condition known as "gustatory hyperhidrosis."
Why do I sweat while sleeping?
People sweat during sleep too. If mild, some may not even notice!
Night sweats are characterized by waking up with a "drenched in sweat" feeling regardless of temperature. It is common and can occur for various reasons, often indicating other diseases or medication side effects.
Does sweating help with weight loss?
Sweating alone does not lead to weight loss and does not burn more calories by sweating a lot. Sweating helps the body lose water weight. This water weight is quickly regained by drinking a few glasses of water.
Does sweating mean I am burning a lot of fat?
No, sweating does not help reduce fat. Although water loss via sweat can temporarily reflect weight loss (during long workouts, you can lose 1-2 kg of water), this is not fat and will be regained with rehydration after exercise.
Does more sweat indicate a better workout?
Not necessarily. Sweat volume during exercise depends on many factors, including environmental temperature, your fitness level, age, and weight.
What can sweating indicate?
Heavy sweating can be a sign of an abnormal condition. It may be due to a disease or medication side effect.
If your sweating has changed recently, consult a doctor to rule out any illnesses. Many medications are known to increase sweating.
If no disease or medication is involved, excessive sweating may be caused by primary hyperhidrosis.
DermaDry Total Hyperhidrosis Treatment Device
The DermaDry Total is a device designed for home use that provides a very simple solution for treating abnormal sweating on the palms, soles, and underarms.
Does sweat cause acne?
No! Sweating by itself does not cause acne. In fact, it can help prevent it because sweat contains antibacterial proteins that kill common bacteria responsible for acne.
Does sweat have an odor?
Sweat is an odorless fluid. The smell associated with sweat only appears when bacteria living on our skin break down the sweat, releasing a sulfur-like odor. In severe cases, this is called bromhidrosis.
Do I sweat out toxins?
No. Sweat is almost entirely water. Sweating does not detoxify the body. The amount of toxins in sweat is negligible because organs like the liver and kidneys, not sweat glands, are responsible for toxin elimination.
How much does an average person sweat daily?
The human body has 2-4 million sweat glands, which can produce a maximum of 10-14 liters of sweat per day (in adulthood).
Sweat volume depends on many factors, mainly the environmental temperature, but also age, gender, body weight, and fitness level.
An average adult performing sedentary work loses about 450 ml of sweat per day (usually unnoticed), while an athlete can lose up to 1200 ml per hour during exercise.
Am I sweating too much?
Everyone sweats, but sweat volume is normal. If sweating interferes with your daily tasks or you sweat without reason, you may have hyperhidrosis. This condition is characterized by unreasonably strong, excessive sweating (sweating exceeding what is necessary for body temperature regulation).
When do we talk about excessive sweating?
There isn’t a clear-cut answer, but if sweating affects your daily life, it’s worth seeking treatment or consulting a healthcare professional.
The human body is about 73-75% water, and losing even 1% can cause dehydration.
What types of sweating disorders exist?
Anhidrosis or hypohidrosis: the patient is unable to sweat, which can cause life-threatening conditions during heat waves because the body cannot lower its temperature and overheats.
Bromhidrosis: characterized by very unpleasant body odor.
Chromhidrosis: a very rare condition where sweat is colored instead of clear.
Hyperhidrosis: A very common condition characterized by excessive (abnormally strong) sweating.
Why does my body sweat without reason?
If uncontrollable, excessive sweating is not caused by disease or medication side effects, it is likely a condition called primary hyperhidrosis.
What is compensatory sweating?
Compensatory sweating is a common side effect of hyperhidrosis surgery. Cutting the nerve fibers in the treated area completely stops sweating there, but the body compensates with increased sweating in other areas. Although sweating stops in the original area, it appears again elsewhere.
What can I do about sweating?
Abnormal sweating (hyperhidrosis) is generally a treatable condition.

If abnormal sweating affects your palms, soles, or underarms, you’re fortunate, as there is a highly effective treatment called tap water iontophoresis. In my experience, more than 95% of those treated report favorable effects, meaning the method helps.
If you sweat on your scalp, neck, back, chest, abdomen, or thighs, meaning large areas are affected, this method (currently) is not applicable because there is no device capable of treating such a large area simultaneously.
