Naturally occurring lithium in public drinking water may have an anti-suicidal effect – according to a new study from Brighton and Sussex Medical School (BSMS) and the Institute of Psychiatry, Psychology & Neuroscience at King’s College London. Published in the British Journal of Psychiatry, the study collated research from around the world and found that geographical areas with relatively high levels or concentration of lithium in public drinking water had correspondingly lower suicide rates.
