Many diseases increase in winter, especially the risk of heart attack is more in this season. Research has shown that heart attacks are more severe and severe in the cold weather. According to a report by the Journal of the American Heart Association, the rate of deaths related to heart disease rises sharply between December 25 and January 5.
Professor Stephen P. Glasser of the Birmingham School of Medicine says that during the winter months there is a change in the daytime hours, a change in which the balance of hormones such as cortisol also deteriorates, causing additional pressure on the heart. Due to the cold temperature, the arteries become hard, blood flow is obstructed. Because of this, the oxygen supply to the heart decreases and the risk of heart attack increases.
Glasser says, ‘In cold weather, the heart needs oxygen more because it has to work a lot to maintain heat in the body. Studies have shown that problems related to heart attack and heart disease are more frequent in the morning.
Researchers say that most people have a heart attack or stroke due to increased blood pressure in the morning. Glasser says that because of the early darkness in winter, people do most of their work in the morning. Due to the change in the time of activities, it also has an effect on the body, due to which the heart rate and blood pressure are increased and hormones also change.
