Hunger, Caffeine, Cognition

How are these three words related? All three are related to the word adenosine. Adenosine is a molecule that is produced by the brain’s metabolism, during cognitive activity, and when we are hungry. The drug caffeine blocks the effects of adenosine. When I am hungry, I find thinking difficult. This would explain why. In both cases, I am feeling the effects of adenosine. Caffeine assists me in putting off eating. When I have been doing a great deal of cognitive effort, I am feeling the effects of adenosine. Caffeine is a drug that restores mental energy by blocking the effects of adenosine.

There are other ways of refreshing our brains. Exercise, even brief amounts of exercise, can be restorative. Meditation is another route to refreshing our brains as is taking a nap. When going the drug route, however, caffeine is quite effective.
