Why do we sweat?
The fascinating function of thermoregulation (sweating) is a natural body process that helps us keep our body temperature constant. Our body is like a high-precision machine that needs a core temperature of around 37 degrees Celsius to function optimally.
How does sweating work?
When we exert ourselves physically, are exposed to a high ambient temperature or are emotionally excited, our body temperature rises. To lower it again, our body produces sweat. This consists mainly of water and some salts. When the sweat evaporates from our skin, it removes heat from our body and cools us down.
Excessive sweating: when thermoregulation gets out of balance
Sweating is a normal process. But sometimes there can be an overproduction of sweat, which is known as hyperhidrosis. Those affected sweat heavily even when it is not necessary, for example when resting or in cool temperatures.
Where does excessive sweating occur?
Hyperhidrosis can occur in various parts of the body, including:
- Armpits
- Hands
- Feet
- Forehead and neck
- Back
- Abdomen
- Buttocks
- Forearms
- Chest
- Skin folds
- Causes of excessive sweating
The causes of hyperhidrosis are varied and can include both physical and psychological factors. Possible triggers are:
- Diseases: Thyroid diseases, diabetes, heart problems
- Medications: Certain medications can have sweating as a side effect
- Hormonal fluctuations: During puberty, during menopause or during pregnancy
- Stress and anxiety
- Genetic predisposition
What can you do about excessive sweating?
The treatment of hyperhidrosis depends on the cause and severity. Possible treatment approaches are:
- Antiperspirants: These drugs constrict the sweat glands.
- Shirts, underwear: With sewn-in armpit pads that absorb large amounts of sweat
- Armpit pads: To be glued or sewn in, made of fabric or fleece
- Iontophoresis device LWI: Direct current therapy device
- Medication: In severe cases, medication can be prescribed.
- Botulinum toxin injections: This treatment blocks the nerve impulses that activate the sweat glands.
- Surgical interventions: In rare cases, surgical interventions can be considered.
