Coffee won’t give you extra energy, just borrow a bit that you’ll pay for later
This cites no data or studies.<p>Companies that created a coffee break during the industrial revolution did see significant productivity and quality improvements.<p>It&#x27;s quite possible that caffeine blocks adenosine and then your body metabolizes it away via another mechanism for it maxes out.  Thus you don&#x27;t end up paying all of it back.  Why? Perhaps our brains may be evolutionarily programmed to use less energy than they could because food was previously much harder to come by.<p>From an energy conservation POV, overproduction of adenosine makes biological sense.
