According to a recent study, irrespective of moving to a place with warmer climate an individual is likely to suffer higher risk of dying from heart-related problems in winter than in summer season.
For the study, researchers at the Good Samaritan Hospital in Los Angles analyzed data from death certificates collected between the years 2005 to 2008 from seven regions in the US having different climatic conditions.
These regions included Los Angeles County, Texas, Arizona, Georgia, Western Washington State, Pennsylvania and Massachusetts. It was observed that in all regions, total deaths and deaths due to heart attack, heart-failure, cardiovascular diseases and stroke rose by an average of 26 to 36 percent between the summer low and winter peak seasons.
Dr. Bryan Schwartz, lead author of the study said that these findings were surprising. The research was not designed to show reasons for rise in the number of heart-problem related deaths during winters.
But Schwartz theorized that people may acclimate to their local climate making their change from summer to winter temperatures relevant as compared to how low the temperature dips in winters.
He added many factors contribute towards increasing the risks of death due to heart-related problems like lesser attention to one’s lifestyle especially neglect of proper diet during winters. People tend to exercise less and gain weight.
In addition, lesser daylight during winters causes or worsens depression symptoms. Higher rate of respiratory infections during winter season is also regarded as a cause for rise in the risk of death due to heart-related problems. This he said could be reduced by reinforcing guidelines for pneumonia vaccines and flu-shots during winter season.
