The body responds to cold by constricting superficial blood vessels, which decreases thermal conduction in the skin and subsequently increases arterial blood pressure. Other responses are shivering and increased heart rate, which raise the metabolic rate and in turn increase body temperature. The risk of suffering a heart attack is more likely to peak in the winter season and decline in summers because air temperature acts as an external trigger for the life threatening disease, an analysis has shown. The findings revealed that the average number of heart attacks per…
