Is it normal to sweat even when it's cold?
Mostly.Normal for most people
Yes, it can be normal to sweat even when it’s cold, especially if you’re bundled up, active, stressed, or naturally sweat more than other people. If it’s new, persistent, or happening without an obvious reason, it’s worth checking in with a healthcare professional.
Yes—cold weather doesn’t switch off your sweat glands. You might be overdressed, walking briskly, feeling anxious, or simply someone who sweats easily; layers can also trap heat even when the air feels chilly.
If you’re sweating heavily when you’re resting and comfortably dressed, or this is a new and persistent change, consider getting it checked—especially if you also feel unwell or have other symptoms.
