Will using the sauna help me to sleep better?

KLAFS FAQ for well-being

One of the positive effects of the sauna is that it can help to reduce sleep disorders if these are caused by nervousness or restlessness. After a sauna, you feel deliciously drowsy, which helps you drop off to sleep sooner and means you wake up less often during the night. You might not sleep for longer overall, but your deep sleep phases are longer and more intense, meaning you wake up feeling significantly fresher and more rested.
