How long should you stay in a sauna?

The recommended time to spend in a sauna is generally between 10 to 20 minutes per session. Studies suggest that this duration can provide cardiovascular and longevity benefits 1 2. It's important, however, to listen to your body and gradually increase your exposure if you're new to sauna use, as overdoing it could potentially cause harm 3. The frequency of sauna sessions can also impact the benefits, with two to three sessions per week showing significant positive effects 1.
