Recovery Science
Your complete guide to
thermal recovery
and light therapy
Research-based guides and comparisons of cold plunge tubs, infrared saunas, and red light therapy panels — with evidence limits, specifications, and tradeoffs to verify before purchase.
Three modalities. Clear evidence limits.
Three widely discussed recovery tools — with practical guidance and evidence limits made explicit.
Cold Plunge
Cold-water immersion may affect soreness and wellbeing in some contexts, but evidence is mixed. We compare equipment using public specifications and practical ownership factors.
Explore cold plungeInfrared Sauna
Infrared products provide heat in different formats. We compare blankets and cabins while separating manufacturer claims from independent evidence.
Explore infraredRed Light Therapy
Red and near-infrared light have condition- and dose-specific research. We explain how to evaluate evidence and consumer-device specifications.
Explore red lightCut through the hype
We review published evidence and state its limits. Product comparisons are research-based unless a page is explicitly labeled hands-on.
Cold Plunge Tubs 2026: Research-Based Comparison
A research-based comparison using public manufacturer information, practical buying criteria, and explicit limits on unverified prices and specifications.
Infrared Sauna Blankets 2026: Research-Based Comparison
A research-based comparison of sauna blankets using public manufacturer information, practical buying criteria, and explicit evidence limits.
Red Light Therapy Panels: What the Science Actually Says
Evidence varies by use case and device. We explain the clinical evidence, why wavelength alone does not establish outcomes, and how to compare consumer documentation.
Recovery Stack Planning: Red Light, Sauna & Cold Plunge Evidence
A conservative way to think about combining modalities, including evidence gaps, timing considerations, and when not to combine them.
Can You Use HSA or FSA for Cold Plunge, Sauna & Red Light? (2026)
What IRS guidance says, why general-wellness purchases are not automatically eligible, and what to verify with your plan.
Budget Recovery Stack Planning (2026)
A budget framework for comparing setup, maintenance, warranty, and evidence without relying on unverified prices.
Cold Plunge vs. Ice Bath: Evidence and Setup Comparison
A practical comparison of setup, temperature control, water care, convenience, and user-specific cost—without a universal breakeven claim.
Infrared Sauna Session Length: Evidence and Safety Limits
Why no universal session length applies, what manuals control, and what dry-sauna evidence does and does not establish.
