How to use this guide
A practical route through evidence-led wellness
01
Separate signal from dashboard noise
Learn which wearable measurements are reasonably useful as trends and which estimates should not drive health decisions alone.
02
Rank the basics first
Sleep opportunity, training load, nutrition, and stress context usually matter before a new recovery device or supplement.
03
Read claims precisely
Distinguish a plausible mechanism from a demonstrated outcome, and population research from a guarantee for one person.

Frequently Asked
How can you tell whether a wellness claim is evidence-based?
Look for a clearly defined outcome, an appropriate comparison, evidence in relevant humans, effect size, limitations, and agreement across more than one study. A mechanism or testimonial alone is not enough.
Which recovery method should you prioritize first?
Start with adequate sleep, appropriate training load, sufficient food and fluids, and time. Add specific methods only when they address a real need and do not displace those foundations.
