Sleep & Recovery
Caffeine can alter your sleep even when you do not notice it.
In a small experiment involving 23 healthy young men, 400 mg of caffeine 12 hours before bed reduced deep sleep by about 21 minutes, with no statistically significant change in overall self-rated sleep quality.

THE BIGGER PICTURE
When Does Healthy Stress Become Too Much?
Frequent sauna use was associated with lower mortality hazards in a Finnish cohort, but sauna frequency is not a measure of stress intensity and cannot establish a causal benefit. Wim Hof-style breathing and cold exposure produce acute physiological changes, sometimes with immediate risks, yet no demonstrated longevity gain. Together, the findings pose an unanswered question: where is the boundary between a recoverable challenge and an unsafe overload? Neither study identifies that threshold.
24%Lower adjusted mortality hazard: 2–3 vs 1 sauna/week
40%Lower adjusted mortality hazard: 4–7 vs 1 sauna/week
Finnish cohort of 2,315 men; median follow-up 20.7 years. HRs 0.76 (95% CI 0.66–0.88) and 0.60 (0.46–0.80). Observational.

THE UNEXPECTED FINDING
The Beaver That Challenges a Simple Diet Story
In a literature compilation covering 68 bird and mammal species, humans were listed at gastric pH 1.5 and North American beavers at pH 1.7. Beavers mainly eat plants. The numbers challenge the idea that highly acidic stomachs belong only to meat-eaters. But the species values came from different studies, and the evolutionary explanation remains uncertain.
pH 1.5 Human stomach
pH 1.7 North American beaver
Separate studies, not a controlled comparison. Lower pH means greater acidity.
