¶ Evidence Summary (Human Outcomes)
| Intervention | Outcome | Human Evidence | Effect Size | Quality of Evidence | Reference |
|---|---|---|---|---|---|
| Sauna Bathing | Fatal CVD Risk | Reduced risk of fatal cardiovascular events (4-7x/week) | ~50% Risk Reduction | High (Prospective Cohort) | [1] |
| Cold Water Immersion | Muscle Recovery | Reduced delayed onset muscle soreness (DOMS) | Moderate (d=0.5-0.8) | High (Meta-Analysis) | [2] |
| Red Light Therapy (PBM) | Skin Rejuvenation | Increased collagen density & reduced wrinkles | Moderate | Moderate (RCTs) | [3] |
| Red Light Therapy (PBM) | Muscle Performance | Reduced muscle damage (CK) & improved recovery | Moderate (d=0.84) | Moderate (Meta-Analysis) | [4] |
| Hyperbaric Oxygen (HBOT) | Diabetic Wounds | Accelerated wound healing | Significant | High (Systematic Review) | [5] |
| Hyperbaric Oxygen (HBOT) | "Anti-Aging" (General) | Telomere elongation (specific protocol) | Emerging / Protocol-dependent | Low (Single RCTs) | [6] |
| PEMF Therapy | Osteoarthritis Pain | Reduced pain and stiffness | Moderate | Moderate (Meta-Analysis) | [7] |
| Grounding / Earthing | Inflammation | Subjective pain reduction | Unclear | Insufficient / Very Low | [8] |
¶ Measurement Readiness
Before you buy hardware, define the metric and the timeline:
- Acute: sleep latency, next-day energy, soreness
- Weeks: performance metrics, resting HR trend
- Months: lipids, HbA1c, body composition
For structured routines, see Biohacking Protocols.
