Study: Drinking Coffee Might Lower Suicide Risk by 50 Percent


Drinking coffee several times a day could actually lower the suicide risk in men and women by 50 percent claims a new study by the Harvard School of Public Health (HSPH).

Caffeine can increase levels of serotonin, dopamine and noradrenaline in the brain. The study suggests this is why there were lower cases of severe depression among coffee drinkers.

“Unlike previous investigations, we were able to assess association of consumption of caffeinated and non-caffeinated beverages, and we identify caffeine as the most likely candidate of any putative protective effect of coffee,” said lead researcher Michel Lucas, research fellow in the Department of Nutrition at HSPH, to the Harvard Gazette.

The 10-year study included 208,424 volunteers, of which 277 committed suicide. The study included all caffeine intake: coffee, sodas, chocolate and tea. About 70 percent of the people used coffee as their main caffeine source.

Two to four cups of coffee a day seems to be the best range for the anti-depressive effects.

However, a study in Finland said that people who drink six or more cups of coffee per day had a slightly higher suicide risk.
