Lithium in water ‘curbs suicide’

Drinking water which contains the element lithium may reduce the risk of suicide, a Japanese study suggests.

Researchers examined levels of lithium in drinking water and suicide rates in the prefecture of Oita, which has a population of more than one million.

The suicide rate was significantly lower in those areas with the highest levels of the element, they wrote in the British Journal of Psychiatry.
