Warm baths or hot showers can provide some sleep benefits and are worth testing for individuals who cannot access saunas.

“So sauna, hot baths to get sleepy, cold showers, ice baths, et cetera to wake up.”

“even though as it relates to sleep you know the benefits of Asana can be there but for those people who don't have access can't get access even kind of like a warm bath or even a hot shower can still have some of those sleep benefits that it's worth people testing before they go to bed those types of activities”

“The bottom line is that many of the "benefits" extend outward from heat stress. This would suggest that (in general) you can probably recapitulate many of the biological effects of sauna with hot bath or steam showers.”
