Heart Attacks More Frequent in Colder Weather

Several factors, including hydrodynamics, may be cause of long-known association

Heart attacks increase with lower air temperature, lower atmospheric air pressure, higher wind velocity, shorter sunshine duration and colder weather. shutterstock

Heart attacks happen more frequently in winter, a major Swedish study confirmed.

Published recently in JAMA Cardiology, the research found the incidence of heart attacks in a sample of more than 250,000 people increased with lower air temperature, lower atmospheric air pressure, higher wind velocity, and shorter sunshine duration.
