The bright lights of the big city might seem dazzling, but they can be hard on your heart health, a new study says.
People exposed to high levels of artificial light have an increasingly higher risk of heart disease, researchers are scheduled to report at a Nov. 10 meeting of the American Heart Association in New Orleans.
Higher exposure to artificial light at night was associated with a 35% increased risk of heart disease within five years, and a 22% increased risk over 10 years, researchers found.
"We found a nearly linear relationship between nighttime light and heart disease: the more night-light exposure, the higher the risk," senior researcher Dr. Shady Abohashem, head of PET/CT cardiac imaging trials at Massachusetts General Hospital in Boston, said in a news release.
