Strong Daily Rhythms Plus Exercise Cut Death Risk by Two-Thirds

Key Insight

This study suggests keeping a consistent daily rhythm alongside regular exercise may meaningfully lower mortality risk.


Adults whose sleep-wake cycles followed a strong daily rhythm and who got enough exercise had a 65% lower risk of dying from any cause over about 7 years. The combo also slashed cardiovascular death risk by 75%. Part of the benefit seemed to come from slower biological aging, hinting that consistent routines matter as much as the workout itself.
