Cooler Weather — More Heart Attacks

Lower outdoor temperatures were associated with greater numbers of patients being admitted to British hospitals with heart attacks – according to research published in the British Medical Journal gathered from records of 84 000 patients admitted with heart attacks between 2003 and 2006. Krishnan Bhaskaran of the London School of Hygiene and Tropical Medicine discusses his group’s finding of an increase of up to 200 heart attacks per day for every one degree Celsius reduction of temperature.
