A U.K. study published in the British Medical Journal found that a 1 degree centigrade reduction in average daily temperature was associated with a cumulative 2% increase in risk of heart attack for the following 28 days. The study also found that elderly people ages 75 to 84 and those with a history of heart disease are particularly vulnerable to the effect of colder weather on heart attack risk, with prolonged exposure to the cold increasing that risk.
