Do men sweat more than women? Causes, triggers & tips for the night

Key points

• Men sweat more and earlier than women. The main reasons are body composition, muscle mass and hormonal balance.

• Women react differently to heat: their bodies start producing sweat at higher temperatures and often more sparingly — but they tend to feel cold more quickly.

• At night, breathable nightwear made from natural fibres makes a noticeable difference, as it wicks away moisture and helps regulate body temperature.

Who sweats more: men or women?

The question of which sex sweats more can be answered fairly clearly: men generally sweat more than women. And that’s despite the fact that women have a similar — and in some cases even higher — number of sweat glands.

The difference lies not in the number of glands, but in their activity. Much suggests that women start sweating later in response to heat and release warmth more efficiently. In colder conditions, however, women tend to feel cold more quickly.

Why do men sweat more than women?

So why are men’s sweat glands more active? Several factors usually come together. The reasons behind strong sweating in men are typically a combination of body composition and hormones.

Men have, on average, more muscle mass and a higher body weight. Muscles consume a lot of energy and generate heat — heat that the body must release through sweating.

Men also tend to have a faster metabolism, which increases energy use and heat production. The more heat generated internally, the harder the body’s thermoregulation has to work.

A central factor is the hormonal balance. The hormone testosterone stimulates sweat production, which is why men start sweating even with relatively low physical strain.

Exceptions: why women sometimes sweat more

Although men usually sweat more than women, this rule is not absolute. During menopause or other hormonal transitions, women’s temperature regulation can change significantly, leading to sudden hot flushes and sweating episodes.

Psychological triggers such as stress or anxiety are also common. If fainting spells or cold sweats occur frequently, the underlying causes should be professionally assessed. A hyperhidrosis (excessive sweating) can often be managed with minimally invasive treatments.

Heavy sweating in everyday life: common triggers

In everyday life, the difference between men and women becomes particularly noticeable — especially during physical activity. During exercise or exertion, the male cardiovascular system often ramps up more quickly, and sweat production increases accordingly.

Warm days also lead to more sweating, as the body tries to cool down and maintain a stable core temperature. Through evaporation on the skin, it releases heat and protects its performance capacity.

There are also everyday triggers that are easy to underestimate: spicy food, caffeine and stressful situations can significantly stimulate sweat production — often a little more strongly in men than in women.

Interestingly, good endurance and regular training make sweating more efficient. Trained individuals start sweating earlier, but they also cool down faster and keep their core temperature more stable.

When does sweating become excessive?

Sweating is a healthy and essential process that protects the body from overheating. Still, many wonder why men sometimes sweat excessively, even at rest and without any obvious trigger.

If very heavy sweating occurs suddenly, only on one side, or completely independent of heat and movement, there can be many possible causes. To understand the reason clearly, a medical evaluation is advisable.

Tip: When sweating heavily, make sure to drink enough. Water is the best way to compensate for fluid loss.

Night‑time sweating: what matters most in men’s sleepwear

Night‑time sweating can feel particularly uncomfortable. Waking up in damp sleepwear and bedding often disrupts rest — and because men release more heat at night, the right sleepwear becomes a crucial factor.

Choose breathable natural fibres such as high‑quality cotton or TENCEL™. These materials support natural thermoregulation, wick moisture away from the skin and help maintain a comfortable body temperature. Loose‑fitting styles allow air to circulate, contributing to a calmer, more restful sleep.

CALIDA’s men’s sleepwear is made from carefully selected natural materials that optimally support temperature balance throughout the night. This keeps you comfortably dry — even on warm nights or when sweating is more intense.

Conclusion

Men generally sweat more than women, and the reasons are clear: more muscle mass, higher body weight, a faster metabolism and the influence of testosterone all contribute to increased sweat production.

Women, on the other hand, respond differently to heat and often begin sweating later. Everyday factors such as exercise, physical strain and warm temperatures amplify the effect.

To ensure sweating doesn’t become a burden at night, breathable sleepwear made from natural fibres is your best choice. It supports your body’s thermoregulation and helps you sleep comfortably — even on warm nights.
