Link between Lithium in Drinking Water and Suicide Rates Confirmed

The first-ever meta-analysis of studies of lithium in drinking water, conducted by a team of researchers from the United Kingdom, confirmed the link between the higher levels of lithium in the public water supply and lower rates of suicide mortality in the local population.Link between Lithium in Drinking Water and Suicide Rates Confirmed

The analysis included data from 1,286 localities across Japan, Austria, the US, England, Greece, Italy, and Lithuania. On average, lithium levels found in the drinking water samples ranged from 3.8 μg/L to 46.3 μg/L, with a few communities peaking above 80 μg/L.

Lead author of the review Anjum Memon, epidemiologist, from Brighton and Sussex Medical School, says: “It is promising that higher levels of trace lithium in drinking water may exert an anti-suicidal effect and have the potential to improve community mental health.”

Lithium in Tap Water May Protect People from Dementia

A new study from the University of Copenhagen, Denmark, suggests that levels of naturally occurring lithium in drinking tap water connected to the lower chances of developing dementia.lithium in tap water protects from dementia

A team of scientists used 151 water samples from across Denmark and developed a comprehensive map of lithium levels in drinking water for all 275 municipalities in the country with the help of the received data.

Compared to those who only got 2-5 micrograms of lithium per liter in the drinking water,  people that consumed at least 10 micrograms had a 17% decrease in their incidence of dementia.

Study: You Should Drink Water Only When You’re Thirsty

A popular rule states that each person should drink at least eight glassed of water a day to stay healthy and keep a healthy weight. Most people find it hard to achieve, though. A new study finds why it is so. The researchers identified a swallowing mechanism that doesn’t allow us to drink water when we are not thirsty.drink water

For the study, a number of participants were asked to drink a considerable amount of water right after exercising (they were thirsty), and later in the day, when they were not thirsty. In both cases, the researchers asked people how difficult it was for them to swallow liquid.

Study co-author Michael Farrell from the Biomedicine Discovery Institute at Monash University, says: “Here, for the first time, we found effort-full after drinking excess water which meant they were having to overcome some sort of resistance. This was compatible with our notion that the swallowing reflex becomes inhibited once enough water has been drunk.”
