Research Library
Everything we publish traces back to published research. This is an honest, plain-English map of where the evidence stands for each therapy — with links to the fully-referenced detail on every pillar.
How we rate the evidence
We label how mature the human research is — not how useful or safe something is — then let you read the detail and decide.
Multiple high-quality human studies consistently support the core effects.
Good-quality human evidence exists, though some questions remain.
Early human research is promising, but larger studies are still needed.
Evidence is mainly laboratory, animal or mechanistic. Human evidence is limited or not yet available.
Evidence by therapy
Sauna
Large observational studies link regular sauna use with cardiovascular and other benefits, and the heat-stress mechanisms are well described. Randomised-trial evidence is thinner — association is not proof of cause.
Read the evidence →Well EstablishedSleep Optimisation
The circadian and behavioural foundations of sleep are among the best-established areas here — light, temperature, timing and consistency.
Read the evidence →Strong EvidenceNervous System Health
Stress physiology, heart-rate variability and slow breathing have a solid base for shifting the body toward rest-and-digest.
Read the evidence →Well EstablishedExercise & Recovery
Training adaptation and recovery are extensively studied; the nuance is in specifics like when to apply cold.
Read the evidence →Emerging EvidenceCold Water
Reasonable evidence for perceived recovery, alertness and short-term inflammation responses; longer-term and mood claims are earlier-stage and vary between people.
Read the evidence →Emerging EvidenceRed Light
Plausible photobiomodulation mechanisms and growing human research on skin, recovery and pain; optimal dosing and consistency of results are still being worked out.
Read the evidence →Emerging EvidencePEMF
Some encouraging findings for pain and recovery, though results vary by device, dose and condition.
Read the evidence →Emerging EvidenceHyperbaric Oxygen
Established for specific medical indications; wellness and longevity uses are earlier-stage and still being studied.
Read the evidence →Well EstablishedLongevity Science
The core levers — exercise, sleep, nutrition, connection — are well-established. Many longevity add-ons are early or unproven; we flag which is which.
Read the evidence →Emerging EvidenceMolecular Hydrogen
An interesting selective-antioxidant mechanism with early but genuine human studies — promising, though larger trials are still needed.
