Since when does sitting in a sauna burn calories?
so imagine if you have just ran for 45 minutes and then jumped straight into a hot environment, this is my routine cardio then sauna. your metabolism is already working at an increased rate so is your heart, breathing, etc. in this hot environment your blood pressure is increased, your body temperature rises and your body then has to actively work to cool it down. this is usually done by producing sweat. do you think it takes zero calories to sweat?
the same way standing in a freezer would burn more calories, your body has to work harder in order to stay warm.
seriously people in here think they know it all, when i usually correct them they usually forget the times i was right, like this one for example.
yes a lot of the weight lost is water weight and that will go back on, in fact it never really comes off in the first place, i usually drink water in, before and/or after the sauna. i am not using it to lose water weight.
the process of sweating uses calories up, the same your breathing uses calories, in fact any process within the body uses calories up, most of them are very small amounts this is why people burn calories whilst they are sleeping, because they are still alive and their body is still working away. the increased blood pressure within a sauna makes your heart work harder, meaning again more calories are used. your breathing is also increased within a sauna, again this has an effect.
these calories are usually insignificant, but my routine is usually worked around the sauna session in order to maximise the benefits.
so for instance i will also have fasted, so imagine a person who has no glycogen, has just done some intense cardio and is now in a 85 degrees celcius room, is he or is he not going to burn more calories than if he was sitting at home on the couch having sat there all day whilst eating food and doing zero exercise?
i do this as an "extra" sure if i was to focus my whole routine on just sitting in a sauna the calories burnt would be insignificant, but that is not what i am doing.
also as i stated above the water i drink is strathmore flavoured water, 1.5 litre bottles with no added sugar and does not contain that god awful sweetener aspartame.
i also sometimes drink asda's own make flavoured no added sugar water, again this also contains some calories. its usually around 10 calories per litre or thereabouts.
volvic also do a flavoured no added sugar water, its the one with the blue lids, i also sometimes buy this and again it also contains calories, again usually around 10 calories per litre.
