The Heartwood Review / Contrast therapy
Peer-reviewed studies on alternating heat and cold: contrast water therapy, contrast baths, and hot–cold immersion protocols. 5 entries, newest first. Every entry links to its source.
Findings suggest contrast water therapy may support proprioceptive recovery and reduce fatigue markers better than passive rest, though the trial was small (40 participants) and limited to a single athletic population.

Results are promising but limited by a small sample of 30 athletes and a focus on immediate post-treatment effects only, with no follow-up beyond one hour.
Frontiers in physiology, 2025 · Trybulski R et al.
Promising signals on lactate and perceived fatigue, but the small trial of 15 swimmers and the absence of a performance benefit mean findings should be treated as preliminary.
Sports (Basel, Switzerland), 2026 · Kino K et al.
Promising findings from a moderately sized single trial (40 participants), but the eight-week, 27-session protocol and sport-specific population limit how broadly the results apply.
Journal of clinical medicine, 2026 · Hagner-Derengowska M et al.
This systematic review of 19 studies concludes the current evidence base is too limited to draw firm conclusions about contrast therapy and cardiometabolic health.
