Perceived recovery the morning after exercise was higher following infrared sauna (3.2 out of 5) than passive recovery (2.6 out of 5)

In a randomised crossover trial, sixteen male basketball players completed a demanding resistance and plyometric session and then recovered either passively or with a single infrared sauna exposure. Fourteen hours later they rated their perceived recovery on a 1-to-5 scale. Mean scores were 3.2 after infrared sauna versus 2.6 after passive recovery, a statistically significant difference; passive recovery also fell below pre-exercise baseline, which did not happen after the sauna session.

For anyone managing recovery amenities in athletic, hospitality or wellness facilities, this points to infrared sauna access after intense training as a plausible way to support how recovered people feel the next morning, alongside its measured effect on lower-body power and soreness in the same trial. The mechanism sits in subjective readiness rather than sleep duration or quality, which did not differ between conditions.

The result comes from sixteen male basketball players in a single crossover design with one week between trials, so it speaks to short-term perceived recovery after a specific resistance and plyometric protocol rather than general populations or repeated long-term use. The effect was clear and statistically significant here, but whether it extends to other exercise types, sexes, or sauna durations and temperatures remains untested.
