The Claim
In young sedentary males, both six weeks of passive heat therapy and moderate-intensity continuous exercise improve aerobic capacity and whole-body insulin sensitivity, even though passive heat therapy does not increase mitochondrial or metabolic markers in skeletal muscle, suggesting that improvements in cardio-metabolic function from passive heat therapy may occur through non-metabolic, microvascular mechanisms.
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 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.

What the research says
1 studyThe study found that sitting in heat helps improve fitness and blood sugar control just like exercise, even though it doesn’t change muscle energy factories. Instead, it improves blood vessel health in muscles, which may explain the benefits.
