The Claim

Coffee intake increases estimated whole-body heat dissipation during sudomotor activation by approximately 5.5 kcal per minute.

Source: Coffee intake may promote sudomotor function activation via the contribution of caffeine

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Drinking coffee increases the amount of heat the body releases during sweat gland activation by about 5.5 kilocalories per minute.

See the scientific wording

Coffee intake increases estimated whole-body heat dissipation during sudomotor activation by approximately 5.5 kcal per minute, suggesting a potential role in energy expenditure under controlled conditions.

Why this might work

Caffeine blocks signals that normally slow down sweat production, causing more sweat glands to activate and release more sweat. As sweat evaporates from the skin, it removes heat from the body at a rate of about 5.5 kilocalories per minute.

  1. Study: Coffee intake may promote sudomotor function activation via the contribution of caffeine

    Coffee makes you sweat more, and sweating helps your body cool down by releasing heat. This study shows coffee definitely makes you sweat more, so it’s likely helping your body lose a bit more heat, even if we didn’t measure the exact calories.
