I have found, having done 100's of hot yoga classes, that the heat to fresh air in a demanding asana practice is key in keeping from getting overly fatigued. Bikram Yoga Ukiahs, (thier website: hotyogaukiah , phone 707HOTYOGA), teachers are trained in keeping your class hot and energised while keeping the room fresh so there is plenty of rejuvenating air to maintain your strength. Doing a hot bikram practice here in Ukiahs extreme summer heat has proven to me the possibility of staying comfortable and cool even when I am in a outside day temperature 100 degrees and up. Body and mind acclimate. Thanks
Pros: Ease in the summer heat.
Cons: Less reasons to complain.
