A new study out of Sweden stated that the risk of heart attack is most likely to happen on Christmas Eve. 
 

Dr. Ryan Lewis, a local physician with Star ER, said it could be due to the cold weather.

“Partly it contributes to places that receive higher amounts of snow fall,” Lewis said. “People are out shoveling snow and doing more physical work can contribute to a heart attack.”

Or, the weather could inspire people to do the complete opposite, he said. 

“The complete other extreme is sitting around not doing much and not exercising,” Lewis said. 

He said it’s also possible holiday stress can add to the increased risk of heart attack. 

Lewis said symptoms to keep an eye out for are chest pain, tightness in chest, shortness of breath. 

However, some symptoms for women could be different. 

If you believe you could be having a heart attack, Lewis said to call 9-1-1 or go to your nearest emergency center.
