Yet another reason to continue with that borderline-problematic coffee addiction: a Harvard University study showed that subjects who had two to four cups of coffee a day were half as likely to commit suicide as those that didn’t.
Researchers examined data from three U.S. studies evaluating coffee and overall caffeine intake every four years. This included 43,599 men enrolled in the Health Professionals Follow-Up Study (1988-2008), 73,820 women in the Nurses’ Health Study (1992-2008) and 91,005 women in the Nurses’ Health Study II (1993-2007). The subjects shared information about their caffeine intake via questionnaires, and the studies involved 277 cases of suicide.
So what about coffee makes it so life-affirming? Harvard’s people speculate it might have to do with its stimulative properties, which boost serotonin, dopamine and noradrenaline, AKA the neurotransmitters that make you happy.
