Nope, coffee won’t give you extra energy

Many of us want (or should I say need?) our morning coffee to give us our "get up and go." Altogether, the people of the world drink more than 2 billion cups of coffee each day.

You might think coffee gives you the energy to get through the morning or the day — but coffee might not be giving you as much as you think.

The main stimulant in coffee is caffeine, and the main way caffeine works is by changing the way the cells in our brain interact with a compound called adenosine.
