Athletes will go to excessive lengths to increase efficiency. Powerlifters devour hundreds of energy for a grimy bulk to hit their weight class for the subsequent meet. Cyclists deprive themselves of caffeine, solely to load up with an enormous dose proper earlier than a race for a efficiency increase. Now, distance runners are leaping in with their very own shocking tactic: utilizing saunas to enhance their time to exhaustion, all to keep—and even surpass—their race occasions.
In a study printed in the Journal of Science and Medicine in Sport, researchers adopted six male distance runners over a three-week interval. During this time, the runners underwent three weeks of post-training sauna classes and three weeks of management training, with a three-week washout interval.
During the sauna section, the runners sat in a damp sauna at 89.9°C for 31 minutes after every training session, averaging round 12.7 classes. Before and after every sauna session, the contributors accomplished a treadmill run for about quarter-hour or till exhaustion, at their present greatest 5k race tempo. They additionally measured blood markers like plasma and red-cell quantity.
The researchers concluded that sauna use elevated the time to exhaustion by 32%, which corresponds to a 1.9% enchancment in endurance. Plasma and red-cell quantity additionally elevated by 7.1% (5.6-8.7%) and three.5% (-0.8% to 8.1%).

Researchers imagine that the elevated blood quantity that developed over the three weeks of post-exercise sauna bathing was answerable for the considerably enhanced endurance efficiency.
In 2020, a study printed within the European Journal of Applied Physiology confirmed the identical. In this research, researchers adopted 20 educated middle-distance runners. The runners had been cut up into two teams: one group who continued their regular training routine and one other who added sauna classes at round 101–108°C, 5–10% humidity post-workout. The sauna group continued their sauna classes for about 28 minutes, thrice every week, for 3 weeks.
Before and after the training interval, all contributors accomplished a number of assessments, together with one to measure their warmth tolerance throughout a run, a VO2max take a look at to measure cardio capability, and a lactate threshold take a look at.
At the top of the research, researchers found that not solely did the sauna classes enhance the athletes’ warmth tolerance and lactate threshold, but additionally improved their VO₂ max by 0.27 L/min.
The backside line? Sauna classes do greater than rev your metabolism and help coronary heart health—they may additionally make it easier to maintain your tempo longer when it counts most on race day.
