Many of us need a cup of coffee in the morning to give us energy and motivation. Globally, over 2 billion cups of coffee are consumed every day.
Although you may believe that coffee gives you the energy you need to face the day, this may not be the case. The main stimulant in coffee is caffeine. And its functioning is based on altering the interaction of brain cells with a compound called adenosine.
Adenosine is a substance that is part of the system that regulates the sleep-wake cycle. When we do some business, the level of adenosine increases. This is because it is released as a byproduct when energy is used.
As a result, adenosine begins to act in a way that makes the person feel drowsy and tired.
Caffeine can really help with morning drowsiness. But only for a while. It acts by preventing adenosine from functioning properly and preventing you from feeling drowsy.
As a result, when caffeine breaks down, the person begins to feel drowsy and tired again. And the only way to get rid of that fatigue is to sleep.
In addition, caffeine can increase cortisol levels in the body, that is, the stress hormone. As a result, you will also feel more energetic.
