Impact of Light Exposure on Health and Lifespan
A study by researchers from Flinders University highlights the health risks associated with exposure to artificial light at night and insufficient daylight during the day, which can disrupt circadian rhythms and increase mortality risk. The study, involving 88,905 participants, found that high night-time light exposure was linked to a 21-34% increased risk of death, while high daylight exposure was linked to a 17-34% lower risk. The findings suggest that maintaining natural light cycles could promote better health and longevity.
