Office worker A habitually operates a coffee machine as soon as he wakes up in the morning. It’s morning coffee to wake up the daze. It is pointed out that A’s habit may rather be a choice to reduce brain efficiency and only increase caffeine resistance.

Our bodies secrete a hormone called ‘Cortisol’ to awaken ourselves the moment we wake up. This is called cortisol arousal reaction (CAR). Usually, the concentration peaks between 30 and 45 minutes immediately after waking up, and when caffeine, an external stimulus, enters during this period, our body becomes confused.

Brain science researchers at Georgetown University in the United States warn that caffeine has two side effects when cortisol levels are high. The first is that caffeine’s arousal effect is halved, and the second is that the body loses its ability to create energy on its own and turns into a caffeine-dependent human being. In other words, drinking coffee right after waking up injects fake energy into our brain.

Then, when can you maximize the effectiveness of coffee and raise your intellectual ability to the highest level. The golden hour suggested by the researchers is two hours after waking up. In the standard of general office workers, it is between 10 a.m. and 11:30 a.m.

This is the point at which cortisol levels, which soared rapidly, begin to drop slowly. At this time, caffeine perfectly binds to the “adenosine” receptor, a fatigue substance in the brain, and explosively increases concentration and cognitive ability. Beyond simply waking up, it creates a state where work efficiency and creativity peak.

The real role of caffeine is not to create energy, but to block the binding of adenosine that makes the brain feel tired. Adenosine builds up in the brain as you wake up longer, but this substance does not accumulate enough in the early morning, so caffeine lacks food to combine with.

If you want to achieve the best work performance, you need to redesign your caffeine strategy. First of all, you should make a habit of drinking a glass of water instead of coffee for at least an hour after waking up. This is a healthy way to help natural awakening by increasing blood flow to the brain, which has been lacking moisture overnight.

It is effective to drink the first coffee around 11 a.m. The caffeine consumed at this time activates the brain’s engine in an optimal state. Finally, it is wise to choose decaffeinated drinks as much as possible after 2 p.m. The half-life of caffeine is longer than expected, so late intake interferes with the brain washing process through deep sleep and eventually creates a vicious cycle that increases fatigue the next morning.
