Suicide rate rises in hot weather

August 1, 2007

The damp summer may have made us all miserable, but research suggests it is hot weather that poses a far more serious problem for vulnerable people.

A team from London’s Institute of Psychiatry found that suicide rates go up during hot weather.

Analysis of more than 50,000 suicides in England and Wales between 1993 and 2003 showed the suicide rate rose when average daily temperatures topped 18C.

The study appears in the British Journal of Psychiatry.

The researchers found that once the daily average temperature rose above 18C each further degree increase was associated with a rise in suicides of almost 4%.

The rate in the rise of violent suicides was even higher, at 5% per degree rise in temperature.
