Infrared Sauna Workouts

Infrared sauna workouts sell detox and calorie burn, but the extra expenditure is trivial—about 50 calories per 30-minute session above rest. Exercising in extreme heat raises heart rate but also increases dehydration risk, with a 2019 study showing a 40% higher rate of heat exhaustion in heated rooms versus standard gyms. When compared to #6 Barre Classes, which at least provide functional movement, infrared sauna workouts risk more harm for less benefit, and they fail to outperform a simple walk in calorie burn.
