Is a sauna session good before bed

Yes—an evening sauna may help you relax and fall asleep. A session of about 15–30 minutes warms you up; afterward, your body’s cooling response can lower core temperature and support sleep. 1 2

• Cool off afterward: Step out and let your body cool; a cool-ish or warm shower afterward is suggested. 3
• Replace fluids as needed: Sauna causes water loss, so rehydrate, but a guest notes that drinking a lot right before bed can mean waking during the night. 4 5
• Adjust the timing to your response: People differ; if an evening session interferes with your sleep, change the timing. 6
