Light pollution during night sleep — as little as moonlight or light coming through a door gap — takes a toll on human hearts, according to a new study published in the European Heart Journal.
“Exposure to higher levels of light at nighttime is linked to cardiac remodelling,” Lu Qi from Tulane University, New Orleans, USA, who led the research, said in a press release. “This is where the structure and function of the heart changes and we typically see it in response to chronic stress or injury to the heart.”
