Sleeping less than 7 hours daily? You could live a shorter life

A new study by Oregon Health and Science University found that sleeping less than seven hours a night is linked to reduced life expectancy across US counties. Insufficient sleep increases risks of chronic diseases, mood swings, weight gain, and poor focus; experts recommend 7-9 hours nightly. Tips for better sleep include consistent sleep schedules, avoiding screens before bed, and creating a cool, dark, quiet environment.
