Bikram Yoga Missoula Montana
If I can't get to a studio to practice in class, will I get any benefit from practicing at home in a normally heated room?
You must heat the area where you do your yoga. If you can, you should try to heat it to at least 100 degrees F. You should sweat a lot when you do your hatha yoga. If your bathroom is large enough, you can preheat the room with a space heater, and by running the shower with hot water, leave the water in the tub as this will keep the room hot. If you have difficulty heating an area to 100 degrees, then you must wear warm up clothing while you do your yoga. This will keep the heat from escaping the body.
 
I cannot overstate the importance of doing your hatha yoga in heat. Doing your yoga in a cold environment can bring harm to your body. Remember you are changing the construction of your body as you perform these postures. Suppose you are going to make a sword. You start with a piece of fine steel and the first thing you do is put the steel in the fire and heat it up. When the steel is hot it becomes soft. Then you can hammer it and slowly you make it change shape to the sword you want. This is the natural way. Now if you don't heat it up and start hammering the cold steel nothing is going to happen to the steel but you'll break your hand, the hammer, your arm and all the connecting joints. The same thing happens when you do any exercise, even hatha yoga, in a cold environment. When you do your hatha yoga in the heat, your body is malleable.
 
If this is completely impossible to arrange, then move more slowly and carefully, and breathe more deeply into the postures.
