Caffeine-more is not always better.

Updated: Mar 30, 2023

Did you know there is a rebound effect from caffeine that causes you to

feel more tired?



  • Caffeine interacts with adenosine receptors in the brain and blocks sleepiness, but when the caffeine effects wear off, the normal adenosine binding causes even more drowsiness.

  • Then, of course we reach for more caffeine, promote the cycle and ultimately interfere with our sleep.

  • Getting more and better quality sleep is a preferred option. If you feel tired, try drinking some water or getting up and taking brief walk.

  • We can fall into a vicious cycle of caffeine to wake up and then alcohol to calm us down at night. Both substances interfere with good sleep.


So, enjoy coffee or tea, but try not to use caffeine as medication–like all drugs, there are side effects.
