Short answer: 20–40 minutes, at 120–150°F, 4–7 times a week. Here's how to dial it in without overdoing it.
Start conservative
If you're new, begin with 15–20 minutes and see how you feel. Infrared saunas run cooler than traditional Finnish saunas (which hit 180–220°F), so sessions feel more comfortable — but the heat still adds up.
Build to 30–40 minutes
As you adapt over a week or two, most people settle into a 30–40 minute session. The cardiovascular research that made saunas famous was built on frequent, sustained sessions — so consistency matters more than pushing the temperature.
How often?
The population data favors high frequency — 4 to 7 sessions per week is where the strongest associations show up. Daily is safe for most healthy adults.
Timing tip for sleep
An evening session works with your biology. Heat raises your core temperature; the drop afterward helps signal sleep. That's why an infrared session pairs so well with a wind-down routine.
Hydrate
16 oz of water before, 16–32 oz after. You'll sweat — that's the point.
Listen to your body. Lightheaded, dizzy, or too hot? Step out. This isn't a competition.
Make it a ritual
A 2-Person Infrared Sauna turns this into a daily habit at home, and pairing heat with gentle PEMF therapy is a powerful wind-down — which is exactly why we built the Sleep Stack. Browse the Sleep & Relaxation collection.
