Our Mission
The cold plunge space is dominated by two extremes: hardware brands selling you a $5,000 tub, and motivational accounts telling you Wim Hof cured everything. Neither will cite a single peer-reviewed study.
FrostWell exists to occupy the honest middle ground. Every protocol we publish is built on actual research. Every claim links to its source. We translate the science — we do not manufacture it.
"Cold water immersion activates norepinephrine release by 200–300%, with measurable effects on mood and focus lasting hours."
Šrámek et al., J. Physiology (2000)
Research Protocols
Post-exercise cold water immersion can reduce muscle soreness by up to 40% — but the same mechanism that blunts inflammation may also blunt long-term strength adaptations. We break down the research so you can make an informed choice based on your actual training goals.
A 2022 study in Neuroscience found sustained dopamine increases of 250% following cold water immersion — longer-lasting than most stimulants.
Effective BAT activation requires specific water temperatures and durations. Most guides get this wrong. Here is what the metabolic research shows.
The 2016 Dutch RCT showed a 29% reduction in sick days for regular cold shower practitioners — but effect sizes vary considerably across the literature.
How We Work
When we write that a 3-minute cold plunge at 14°C increases norepinephrine by 300%, we link to the specific trial. When the evidence is mixed, we say so plainly. When we do not know, we say that too.
FrostWell follows an evidence grading system adapted from clinical research: systematic reviews carry more weight than single studies, RCTs more than observational data. You always know how strong the evidence is.
"Regular cold water immersion is associated with significantly higher subjective well-being scores in healthy adults — effect sizes comparable to moderate aerobic exercise."
Buijze et al., PLOS ONE (2016) · Grade A Evidence
Protocol insight
The Buijze trial used 30-second daily cold showers — not full plunges. Meaningful benefits do not require extreme exposure. Start where the evidence starts.
