Take the 2-minute tour ×  My bodybugg gadget actually seems to
think that I'm burning more calories when I'm in the sauna, but
I'm kinda skeptical. Does sauna time really accomplish anything?

down vote accepted  I would be skeptical as well. Although there
may be an increased metabolic load to cool the body, it seems to
me that the readings are more likely to be related to
measurement error of the Bodybugg.  According to the company,
the Bodybugg contains four sensors:    1. Accelerometer   2.
Heat Flux (amount of heat being dissipated by the body)   3.
Galvanic Skin Response (skin conductivity)   4. Skin Temperature
The heat flux and skin temperature sensors are likely calibrated
for room temperature and could be thrown off by the relatively
high ambient temperature of a sauna. The GSR sensor could be
affected by the humidity in the sauna (wet skin is more
conductive than dry skin).  share|improve this answer Are you
