!!!! Watch The Water!!!!

How our drinking water could help prevent suicide

Some researchers think putting lithium in our water could save lives.

Lithium is a potent psychiatric drug, one of the primary prescribed medications for bipolar disorder. But it’s also an element that occurs naturally all over the Earth’s crust — including in bodies of water. That means that small quantities of lithium wind up in the tap water you consume every day. Just how much is in the water varies quite a bit from place to place.

Naturally, that made researchers curious: Are places with more lithium in the water healthier, mentally? Do places with more lithium have less depression or bipolar or — most importantly of all — fewer suicides?

A 2014 review of studies concluded that the answer was yes: Four of five studies reviewed found that places with higher levels of trace lithium had lower suicide rates. And Nassir Ghaemi, the Tufts psychiatry professor who co-authored that review, argues that the effects are large. High-lithium areas, he says, have suicide rates 50 to 60 percent lower than those of low-lithium areas.

“In general, in the United States, lithium levels are much higher in the Northeast and East Coast and very low in the Mountain West,” he told me on a new episode of the Vox podcast Future Perfect. “And suicide rates track that exactly — much lower suicide rates in the Northeast, and the highest rates of suicide are in the Mountain West.”

If you apply that 50 to 60 percent reduction to the US, where about 45,000 people total died by suicide in 2016, you get a total number of lives saved at around 22,500 to 27,000 a year. That’s likely too high, since you can’t reduce suicide rates in places that are already high-lithium. Ghaemi’s own back-of-the-envelope calculation is that we’d save 15,000 to 25,000.

Ghaemi and a number of other eminent psychiatrists are making a pretty remarkable claim. They think we could save tens of thousands of lives a year with a very simple, low-cost intervention: putting small amounts of lithium, amounts likely too small to have significant side effects, into our drinking water, the way we put fluoride in to protect our teeth.
