This is What 2 Cups of Coffee Per Day Can Do to Your Liver

Caffeine Improves Brain Function and Boosts Metabolism

Coffee contains caffeine, which is the most commonly consumed psychoactive substance in the world. It inhibits the function of an inhibitory neurotransmitter (brain hormone) called Adenosine, and thus enhances the brain activity and stimulates the release of other neurotransmitters like norepinephrine and dopamine, that keep us alert and energetic. Caffeine has also been found to improve mood and boost reaction time, vigilance and general cognitive function. Yet, note that these effects are short-term.

Moreover, caffeine boosts the metabolism by 3-11% and exercise performance by 11-12%.

Coffee Lowers the Risk of Depression and Suicide

Nowadays, depression and anxiety are unfortunately very common. Yet, a Harvard study showed that individuals who drank the most coffee had a 20% lower risk of becoming depressed.

Additionally, researchers have also found that people who drank 4 or more cups of coffee daily had a 53% lower suicide risk.
