The Claim
Six weeks of passive heat therapy, involving 40–50 minutes at 40°C in a heat chamber three times per week, increases skeletal muscle capillarization and endothelial-specific eNOS content in young sedentary males to a similar extent as moderate-intensity continuous cycling exercise, indicating that heat exposure alone may induce microvascular adaptations comparable to those achieved through exercise.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
