Summary
A new study from Tulane University links nighttime light exposure to a higher risk of cardiovascular disease. Researchers found that exposure to more than 3 lux of light, similar to moonlight, was associated with increased risks of heart failure, atrial fibrillation, heart attack, stroke, and cardiovascular death. Sleep experts warn that light disrupts melatonin production, which affects sleep quality and overall health. A 2022 study showed that moderate light exposure disrupted glucose regulation and increased heart rate. Experts suggest using dim, warm light instead of bright or blue light to reduce circadian disruption.
