Seven Hours to Longevity: Sleep More, Live Longer
New analysis of CDC BRFSS data (2019–2025) finds sleep duration is the strongest predictor of life expectancy after smoking: adults who regularly get seven or more hours per night live longer than those who sleep less. Sleep impacts cardiovascular health, immune function, weight, and mood; insufficient sleep often leads to poorer diet and activity. Common barriers include doomscrolling at night, late caffeine, alcohol before bed, little daytime exercise, busy schedules, and weekend sleep irregularity. Practical tips: maintain a consistent sleep schedule, limit blue light and caffeine in the evening, avoid alcohol before bed, exercise regularly, and consult a clinician for persistent sleep problems. About 37% of American adults don’t hit seven hours.
