Does Bikram Yoga raise my core body temperature?

Usually, but not by a lot. We have done a couple of informal tests to monitor body temperature during class and we had some inconsistent results but there was a slight rise in most people. Here's what we found:

Two pregnant women took their temperature before class, at three different times during class and once more after class. Neither of these women saw a noticeable rise in temperature and one of them said her temperature was slightly lower during class than it had been at other times during the day.

On another occasion we took the temperature of twelve people before and after class and we saw an average body temperature rise of 2.8 degrees. Those who we measured in the morning classes saw a greater rise: 4.5 degrees, but their starting temperature was lower than normal by a couple degrees (most people's body temperature drops a little during sleep and it takes a little while to normalize after waking). Those who were monitored at evening classes saw a rise of 1.7 degrees.

The highest body temperature recorded immediately after a class was 101.5 with an average post-class temperature of 99.7, which is only 1.1 degrees above "normal".

None of this scientific and these were very small sample sizes but it fits with our overall experience and expectations. If you are pregnant or have any health concerns you should always get permission from your doctor before practicing Bikram Yoga.

Thank you!

Thank you for posting this information... I've wanted to take my temperature during class to see if it actually goes up significantly, but it seemed too disruptive.
