Sauna has same effect as EPO
Sauna & endurance
That means you have more, but thinner blood circulating. If instead of just one visit you go regularly to the sauna then the amount of blood plasma remains high, but your body also starts to make more red blood cells. The researchers were interested to know whether this would lead to improved performance.
Study
After the three weeks the researchers got the test subjects to run until they could go no further on a treadmill. The speed was set on the basis of the runners' fastest time during a 5K run.
Results
According to the researchers, the effect measured is the equivalent of a 1.9 percent reduction in time for five kilometres.
When they analysed the athletes' blood the New Zealanders found that the amount of plasma and the amount of red blood cells had increased. What caused the performance-enhancing effect the researchers are not quite sure, but they suspect that "the end result should be an increase in maximum oxygen consumption".
