All articles ›Can You Actually 'Catch Up' on Sleep? The 2-Week Recovery Window
New research suggests that recovering from chronic sleep loss takes far longer than a single weekend — and that some cognitive deficits persist even after sleep is restored.
BPC-157 and Tendon Healing: What the 2026 Literature Review Actually Says
A new systematic review pulls every published BPC-157 tendon study to date. The animal data are striking; the human data remain almost nonexistent.
Zone 2 Cardio and Mitochondrial Health: Separating Signal From Hype
Zone 2 training is having a moment. A new controlled trial compares it head-to-head with HIIT and finds the two protocols produce different mitochondrial adaptations — both useful, neither magic.
Creatine for Cognition: New Meta-Analysis Finds Modest but Real Effects
Creatine has 30 years of muscle-strength data behind it. A new meta-analysis of 26 trials finally answers whether it does anything for the brain — and the answer is a qualified yes.
Cold Plunges Right After Strength Training May Blunt Muscle Growth
Cold water immersion is popular as a recovery tool — but a new mechanistic trial confirms what previous studies hinted: ice baths within an hour of lifting can reduce hypertrophy signaling.
