Is it normal if coffee makes me sleepy?

In this short article, we will answer the question “Is it normal if coffee makes me sleepy?” by showing you possible reasons for this situation and will discuss whether drinking a lot of coffee is a good or bad idea.

Is it normal if coffee makes me sleepy?

Yes, it is normal if coffee makes you sleepy. And the answer can be in your DNA. We will explain this:

The ability of coffee to keep us alert is one of the key reasons we drink it, and it works very well for most people. However, numerous hereditary factors affect how the body will react to caffeine making it the preferred beverage. 

Caffeine acts as a stimulant on the central nervous system (CNS). These interrelated elements support our ability to control our caffeine intake. The more time caffeine spends in our bodies, the more impacts it has. 

This regulation is made by each person’s metabolism, which in the case of caffeine is controlled by two genes: CYP1A2 and AHR. One creates the enzyme needed to break down ingested caffeine, while the second regulates its creation. 

To put it another way, people who have such a powerful system won’t be as affected by coffee, and they might need to discover other methods to combat post-lunch sleep.

Another explanation for the fact that coffee can sometimes have the opposite effects:

Although it may sound unusual, many who consume coffee report getting more rest. Since coffee is also a narcotic and can be addictive for some users, the amount consumed and the frequency of use of this substance are the main causes of this. 

You must comprehend the concept of “sleep pressure” on the body to comprehend why. When a person wakes up, he is aware that his biological clock will send him back to bed at night since his mood has “run out.” 

The body will even give off several signals that it needs to rest and is exhausted. That’s because ATP, the chemical that ensures the release of energy for the cells to function, is essential to everything a person performs.

Human cells produce the chemical adenosine as a consequence of using up this ATP. Adenosine then begins to attach to brain receptors and induces increased levels of sleep in people.

Caffeine shares certain molecular similarities with adenosine, and because of this, it can bind to receptors in the brain. 

Short-term suppression of sleep pressure caused by taking adenosine’s place results in an increase in energy. Adenosine, however, is still present in the body at this time and is only waiting for its turn to join.

Naturally illustratively, the statement “Once the caffeine wears off, you hit a very high level of sleep pressure’ and you have to pay it back” was made. In this case, getting a decent night’s sleep will be the only method to boost energy levels again.

Can excessive coffee use cause problems?

Yes. You must exercise caution because your body develops a tolerance to caffeine the more of it you consume. Adenosine receptors in the brain increase in number, and the liver starts to create more proteins that break down caffeine. 

It’s as though the brain detects that the person wants to go beyond its sleep limitations and resists the trick that caffeine offers. In this way, caffeine use that is increased or prolonged has a detrimental impact on sleep, which also makes people feel weary. 

It’s a perfect storm for a short-term fix that will make things worse in the long run if you’re getting less sleep, and anxious, and you’re relying on coffee to ameliorate that. 

You can increase the number of shots in your espresso, but the cumulative effect on your sleep quality will remain. Reducing the amount of coffee gradually is the best option in this situation to boost disposition. 

The individual could, for instance, switch up the days they consume caffeine or even switch to just drinking decaffeinated coffee. 

Another alternative is for someone who is exhausted to simply rest and, ideally, get a good night’s sleep. Although these solutions are ideal, they are not always feasible.
