Chcete žít déle? Odborníci upozornili na faktor, který často obětujeme jako první

An analysis of data from the American Behavioral Risk Factor Surveillance System from 2019 to 2025 covering 3,143 US counties revealed a significant association between sleep deprivation and lower life expectancy. Researchers from Oregon Health & Science University considered less than 7 hours of sleep per night as insufficient. Even after accounting for other factors such as physical inactivity, smoking, education, and unemployment, this association remained significant. Although smoking and obesity have an even stronger correlation with life expectancy, researchers were surprised by the strong correlation between sleep deprivation and life expectancy. However, the study is observational in nature, meaning direct causal relationships cannot be inferred for individuals. Adequate sleep is associated with the functioning of many body systems, and its lack can affect metabolic and cardiovascular health.
