whole-body passive heating increases skin blood flow conductance ~30–33% in both young and older adults
Whole-body passive heating increased cutaneous vascular conductance by approximately 33% of maximum in young adults and 30% in older adults, with the absolute increase greater in young adults.
What this means for you
When your skin's blood vessels open up more efficiently, your body can release heat, deliver oxygen, and move nutrients to surface tissues more effectively. This kind of circulatory response is linked to the warm, flushed feeling many people notice — and it suggests the cardiovascular system is actively responding regardless of age.
The published research
Systemic cardiovascular and carotid baroreflex support of arterial pressure during recovery from passive heat stress in young and older adults.
