I’ve heard and read about the benefits of using a sauna in the lead-up to hot races. I’ve used the sauna at the gym where I swim, but during the school year (I’m a teacher) I have a hard time getting there more than twice a week. I qualified for Kona for the first time this year, and would like any help I can get in adapting to the heat.
Amazon has some small home saunas for around $1000, but they also have these gimmicky sauna ‘bags’ for under $200. Any idea if one would get any of the benefits from a regular sauna using one of these ‘bag’ products?
