Cold/Heat Protocols
7 of 7Deliberate Cold Exposure
11 min/week total of cold immersion at 50-59°F across 2-4 sessions. Produces a 250% dopamine increase lasting hours, boosts metabolism, and builds mental resilience.
Finnish Sauna Protocol
Sauna at 176-212°F for 15-20 min, 2-4x/week. The KIHD study (n=2315) showed 40% lower all-cause mortality with frequent use. Triggers heat shock proteins and improves vascular function.
Heat Acclimation Primer
Use controlled heat exposure before hot-weather training or travel to improve heat tolerance gradually.
Cold Shower Progression
Start with 15 seconds of cold at the end of your shower and build up. An accessible gateway to cold exposure that builds resilience, boosts mood, and improves stress tolerance.
Contrast Therapy (Hot-Cold Cycling)
Alternate 3-5 min hot and 1-2 min cold for 3-5 cycles. Creates vascular pumping that enhances circulation, reduces inflammation, and accelerates recovery. End on cold.
Cold Recovery Session
Use short cold-water immersion after selected hard sessions when soreness reduction matters more than adaptation signaling.
Hot Bath Wind-Down
Use a warm bath or shower 1-2 hours before bed to support passive cooling and relaxation.
