Short answer: there's no single right number. Always stay within the maximum session length in your blanket's user manual, set the built-in timer before you begin, start on the shorter and cooler side while you get used to it, and end the session whenever you feel uncomfortable.
1. The manual sets the limit
Each sauna blanket has its own recommended temperature range and maximum session duration, set by the manufacturer for that product. Treat the maximum as a limit, not a target.
2. Use the timer
Set the timer on the controller before you settle in, so the session ends on time even if you lose track. Keep the controller within reach in case you want to finish early.
3. Ease in
Many people start with a shorter session at a lower setting and adjust gradually over several sessions, always within the manual's limits. If you have a medical condition or any doubts, ask a qualified healthcare professional what's appropriate for you.
4. Listen to your body
Comfort varies from day to day. Stop straight away if you feel dizzy, light-headed, overheated or unwell. A shorter session you enjoy is better than a longer one you push through.
Planning the full ritual
Remember to allow time around the session itself:
- Before: a few minutes to unfold, connect and warm up the blanket.
- During: your chosen session time.
- After: a few minutes to rest, then time for the blanket to cool before you fold it away.
