Extreme day-to-day swings in temperature are linked to a significant increase in heart attacks, according to a study by US cardiology researchers. The study showed a 5% increase in the risk of a heart attack for every five jump in temperature differential. Changes of over 2five were linked to greater increases. The effect was strongest on days of higher-than-average temperature. The link is unexplained, but could result from increased stress on the body.
