the short answer is no. generally after time in a sauna you might go to the scale and see that the number is lower but that represents the water you lost from sweating and will increase as soon as you replace those lost fluids which you need to do so you don't become dehydrated. while being exposed to high temps can increase your metabolism and slightly increase the number of calories you burn this is only because your body is working to keep your temperature within normal ranges. once you leave the environment your metabolism will return to normal. bottom line time spent in a sauna would be more effectively used to prepare a healthy meal or more exercise. that being said if you enjoy time in the sauna use it as a motivation tool. reward yourself with some time in the sauna everytime you visit the gym. while i agree with mark about not using a sauna to lose weight saunas do have some inherent health benefits. these come in the form of increased circulation (which is also great for your skin and hair) and relief from some forms of nasal congestion - and of course you can't overlook the benefit of relaxation and what that can do for your well being. many cultures around the world have used saunas as an integral part of their daily lives for centuries and have benefited from doing so. yes
