Can sitting in heat help your muscles like exercise?
Passive heat therapy in sedentary humans increases skeletal muscle capillarization and eNOS content but not mitochondrial density or GLUT4 content.

This study checked if just sitting in a hot room helps muscles the same way as biking regularly. They looked at tiny changes in leg muscles and fitness after 6 weeks.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Doing light, steady exercise—like a brisk walk—can boost the energy powerhouses in your muscles.
Sitting in a hot room for about 45 minutes three times a week might improve blood vessel health in inactive young guys just as much as regular cycling — even if they don’t actually exercise.
Sitting in heat for six weeks doesn’t give young inactive guys the same muscle benefits as regular cardio exercise — things like energy production and fat storage in muscles don’t improve like they do with actual workouts.
Sitting in heat for six weeks can be as good as regular cardio for improving fitness and blood sugar control in young, inactive guys—even though the heat doesn’t change muscle metabolism. The benefits might come from better blood flow in small vessels instead.
