Balancing Daylight Exposure: A Key to Better Health

A new study involving nearly 90,000 participants in the UK suggests that exposure to bright light during the day and darkness at night is linked to lower mortality risk. Participants with bright nights had a 21% to 34% higher risk of premature death, while those with bright days had a 17% to 34% lower risk. The study highlights the importance of maintaining a strong contrast between day and night light exposure to support healthy circadian rhythms, which influence various physiological functions. The findings suggest that light exposure is an emerging risk factor for health and longevity.
