The active ingredient in coffee is caffeine, which is the most widely used psychoactive stimulant in the world.
In the brain, caffeine’s blocks the effects of an inhibitory neurotransmitter called Adenosine.
By blocking the inhibitory effects of Adenosine, caffeine actively increases the firing of neurons in the brain and helps with the release of other neurotransmitters like dopamine and norepinephrine.
2) Smelling Coffee makes you remarkably less stressed.
Researchers at the Seoul National University examined the brains of rats who were stressed with sleep deprivation and discovered that those who were exposed to coffee aromas experienced changes in brain proteins tied to that stress. Note, this aroma study doesn’t relate to stress by itself, only to the stress felt as a result of sleep deprivation. Now, we’re not entirely sure if this means you should keep a bag of roasted coffee beans on your nightstand every night, but feel free to try!
3) Coffee is great for your liver!
A study published in 2006 that included 125,000 people over 22 years showed that those who drink at least one cup of coffee a day were 20 percent less to develop liver cirrhosis — an autoimmune disease caused by excessive alcohol consumption that could lead to liver failure and cancer. Arthur L Klatsky, the lead author of the study, told The Guardian, “Consuming coffee seems to have some protective benefits against alcoholic cirrhosis, and the more coffee a person consumes the less risk they seem to have of being hospitalised or dying of alcoholic cirrhosis.”
Studies have also shown that coffee can help prevent people from developing non-alcoholic fatty liver disease (NAFLD). An international team of researchers led by Duke-NUS Graduate Medical School revealed that drinking four or more cups of coffee or tea a day may be beneficial in preventing the progression of NAFLD.
4) Coffee Helps you Burn Fat and Improve Fitness
There’s a reason why you will find caffeine in most commercial fat burning supplements.
5) Coffee will improve mood and fight depression!
A study done by the Harvard School of Public Health determined that drinking between two and four cups of coffee can reduce the risk of suicide in men and women by about 50 percent. The proposed reason is because coffee acts as a mild antidepressant by aiding in the production of neurotransmitters like serotonin, dopamine and noradrenaline.
