Hidden truth: Nighttime light disrupts sleep, raising heart risk.
New research links artificial light at night to increased cardiovascular disease. Exposure to light while sleeping affects our body clocks. This disruption may raise the risk of serious heart problems.
Scientists are uncovering a direct connection. Our internal body clocks, or circadian rhythms, are sensitive. Evening light interferes with these natural cycles. This interference can lead to inflammation. It also impacts blood pressure regulation.
This is not the first time science has warned about light. Back in the early 2000s, studies began to link shift work to health issues. Artificial light at night was a key factor then. Now, the focus sharpens on everyday exposure. It highlights how modern living impacts our most basic biological functions.
The findings suggest simple changes could help. Reducing screen time before bed is advised. Dimming household lights in the evening is also recommended. These steps may protect heart health.
Experts are now exploring personalized interventions. Understanding individual light exposure patterns will be key. Future studies will shed more light on specific protective measures.
