Lose Weight in Sauna, Losing Water Weight by Perspiration in Sauna
Does Taking a Sauna Help to Lose Weight?
Extreme temperatures – either hot or cold – can increase metabolic rate by up to 20 percent.
A sauna may increase the number of calories you burn for up to three hours afterwards.
However, any weight loss incurred during the sauna is likely to be water-loss from perspiration, and this weight loss will be regained as soon as you drink fluids.
