A recent study conducted by Monash University in Australia has found a significant link between exposure to artificial light at night and an increased risk of developing type 2 diabetes.
The research, which included participants aged 40 to 69, monitored the effects of light exposure using wrist devices over a week and tracked their health for nine years.
Moreover, the findings revealed that individuals who were frequently exposed to artificial light between 12:30 AM and morning had a 67% higher risk of developing type 2 diabetes. The study did not establish a direct cause-and-effect relationship but highlighted a strong association between artificial light exposure and the onset of diabetes.

Researchers suggested that artificial light disrupts the body’s internal clock and impairs sleep, contributing to the increased diabetes risk. They recommended avoiding artificial light after midnight to help prevent the disease.
This study aligns with previous research, including a 2022 study in China that found a 28% increased risk of diabetes among those sleeping in artificially lit rooms. The Monash University study’s findings were published in The Lancet Regional Health Europe, while the Chinese study’s results were published in Diabetologia
