Scientists in Britain have discovered that for every one degree Celsius drop in temperature, the relative risk of heart attack increased by 2%, and was seen for up to two weeks after the weather turned cold in the fall.
These findings were based on an analysis of over 84,000 hospital admissions in 15 urban areas over a 4-year period. The elderly and those with a history of heart disease had the strongest association. The authors suggested some possible things that might explain this connection, but more research is necessary to fully understand it.
PositiveTip: While not fully understood yet, it might be wise for people at high risk to be aware of this association and take appropriate steps to stay warm.
