Impact of Blue Light on Appetite and Metabolism

Exposure to blue-rich light at night leads to increased appetite and snacking, while disrupting metabolic processes like glucose metabolism. Studies show that individuals exposed to blue light exhibit higher insulin resistance, decreased glucose tolerance, and increased risk of obesity and diabetes. This effect is evident in night shift workers and individuals who sleep with lights on, highlighting the detrimental impact of artificial blue light on overall health.
