Underarm sweat is initially a normal bodily function. When sweat evaporates on the skin, the body releases heat and protects itself from overheating. Under the arms, however, moisture is particularly noticeable: dark spots on clothing, a damp feeling on the skin, or concern about odor can be unpleasant. Sweaty armpits are therefore not automatically pathological. What matters is whether the amount of sweat fits the situation and how much it affects daily life. The guide sweating under the armpits<\/a> explores the key connections in depth. <\/p>\n\n

Why do you sweat particularly heavily under the arms?<\/h2>\n\n

The armpits contain many eccrine sweat glands. They release a predominantly watery secretion and are controlled by the autonomic nervous system. Heat, exercise, and physical work activate them for cooling. Stress, nervousness, or anxiety can also increase sweat production within a short time. Because the armpit is a warm, poorly ventilated skin fold, moisture evaporates more slowly there than on exposed parts of the body. <\/p>\n\n

Fresh sweat is largely odorless. The typical odor arises primarily when skin bacteria break down components of sweat and other skin secretions. Sweat quantity and odor formation are therefore not the same problem. Read more about how it develops and how to manage it under underarm odor<\/a>. <\/p>\n\n

How much sweat under the arms is considered normal cannot be answered with a fixed milliliter amount. According to the AWMF guideline on primary hyperhidrosis<\/a>, excessive sweating is present when sweat production exceeds the requirements of heat regulation. Visible stains alone do not prove a medical condition. <\/p>\n\n

What causes excessive underarm sweat?<\/h2>\n\n

Common causes of underarm sweat are high temperatures, movement, excitement, tight clothing, and individual triggers such as alcohol, nicotine, caffeine, or spicy food. Hormonal changes, such as during puberty, pregnancy, or menopause, can also temporarily increase underarm sweating. <\/p>\n\n

If heavy sweating under the arms occurs repeatedly without an appropriate cooling need, primary focal hyperhidrosis may be the cause. In this condition, the sweat glands are not more numerous or larger, but overstimulated. Typical features include onset before age 25, bilateral and symmetrical occurrence, complaints at least weekly, and impairment in daily life. This form usually subsides during sleep.

Secondary hyperhidrosis is different. Here, sweating can be triggered by another cause, for example: <\/p>\n\n
