New research has found a connection between sleeping in a room with artificial light and obesity.

The study, which was published in JAMA Internal Medicine, reports on a cohort of 43,722 women.  

The presence of artificial light while sleeping was linked with an increased risk of weight gain and obesity, particularly in women who slept in a room with a television or light on.

The research suggests that lowering exposure to artificial light while sleeping might be useful in obesity prevention.

They highlight that exposure to artificial light may affect sleep quality, which can then influence diet and exercise patterns.

Women who had a higher exposure to artificial light at night were less likely to have consistent waking and bedtime patterns and more likely to take longer to fall asleep, wake up at night and take naps.
