Before we get into caffeine, we must know about adenosine. Adenosine is the chemical in your body that makes you feel tired. It is naturally occurring. It does this as the day wears on to tell you it is time to get some rest. Caffeine gives us the kick that energizes us by preventing adenosine from doing its work.
But besides giving people the energy boost people sometimes need to get through the day–usually in the form of coffee–health benefits have been tied to the substance. Caffeine can keep dopamine levels active, which can prevent the development of Parkinson’s disease. Researchers in Brooklyn College have found that men who drink four cups of coffee a day were over 50% less likely to succumb to heart attacks.
If you nix the sugar in coffee you can actually help stave off diabetes. This has been tied to the high number of antioxidants in coffee.
Now you don’t have to feel so guilty next time you go for a second cup!
