Contrast therapy (hot/cold)
Sleep & Recovery · Thermal
Tier B-
Bottom line
Read Off Label grades Contrast therapy (hot/cold) as B- (6.3/10) based on moderate evidence, med / varies benefit magnitude, and a low-med-risk safety profile.
Common in athletic recovery protocols.
Typical use: Alternate 3-4 min hot (sauna/hot water) with 1-2 min cold; 3-5 rounds; end on cold — N/A.
What this is
Common in athletic recovery protocols. Limited direct evidence for longevity claims beyond component sauna/cold effects.
Mechanism
Alternating vasodilation/vasoconstriction drives vascular pumping; autonomic nervous system training; lymphatic flow
Dose & route
Alternate 3-4 min hot (sauna/hot water) with 1-2 min cold; 3-5 rounds; end on cold
