# Jack Kruse: The Habits Worth Keeping (2026)

> Kernel-only ranking: circadian light, night hygiene, moderate cold, seafood omega-3s, meal structure, and an explicit quarantine list—not an endorsement.

The short answer

Extract **circadian light hygiene** and a few nutrition/behavior kernels; quarantine EMF primacy, structured-water therapy, and cure-list cold thermogenesis. Photobiology reviews such as [Foster et al. on entrainment](https://journals.sagepub.com/doi/10.1177/14771535211014792) stand on their own. Full graded dossier: [Jack Kruse evidence dossier](https://healthcanon.com/expert-dossiers/jack-kruse-evidence-dossier).

Neurosurgery credentials do not auto-validate quantum lifestyle franchises. Origin weight-loss stories remain n-of-one evidence.

## How to read ranks

Higher ranks mean stronger independent evidence after shell removal—not stronger loyalty to any personality brand.
