A published study in The World Journal of Biological Psychiatry has highlighted that drinking coffee is associated with lower suicide rates in adults. According to Harvard School of Public Health (HSPH) researchers, the data has been reviewed for the research. The study validates coffee addiction.

After authenticating the data by studying three large US studies, the researchers studied the data. They studied the consumption of caffeine, coffee and decaffeinated coffee every 4 years. This study was accompanied with food-frequency questionnaires. Death certificates were reviewed to check the suicidal cases.

It was observed during the study that 277 deaths resulted from suicide. It unveiled that the vulnerability of suicide for adults who consumed approximately two to four cups of coffee each day was less. This is 50% poorer in comparison to adults who drank decaffeinated coffee.

The researchers concluded that caffeine acts as a mild anti-depressant. This is done after stimulating particular neurotransmitters in the brain. They encapsulate noradrenaline, dopamine, and serotonin.

There have several studies in past that have asserted that coffee and good work can go hand-in-hand. Previous studies have said that coffee has the potential of reducing probability of skin cancer and Alzheimer's. There have been studies that have shown that it can reduce heart failure and diabetes risks, increase concentration, and even guard liver health. Now, it has validates that it can reduce suicide rates.
