What Causes Tiredness After Coffee?

Coffee Blocks Adenosine

Our sleep cycle is controlled by the chemical adenosine, which is produced in the central nervous system. Adenosine levels rise during the day to keep us alert, much like melatonin, the hormone that promotes sleep. They become less at night to aid in sleep. Adenosine accomplishes this by attaching to specific brain receptors that reduce activity and promote calm. Caffeine binds to these receptors when you consume coffee, blocking adenosine from reaching them.

Even though the receptors are not taking it in the body still makes adenosine in the morning. The chemical then accumulates in the body as a result. High quantities of adenosine produced after caffeine has been digested may result in acute weariness.
