Reasons Why Coffee Makes You Sleepy

Here are a couple of reasons coffee makes you feel sleepy.

1. Coffee Blocks Adenosine 

You might be wondering what is Adenosine and what does it have to do with coffee? Adenosine stimulates or manages the sleep-wake cycle in the body while coupling cerebral blood flow in the body. 

When you drink coffee, it binds to the Adenosine receptors. Coffee doesn’t stop the production but delays it. Once the effect wears off, the brain is rushed with Adenosine that eventually leaves you with a caffeine crash or feeling very sleepy forcing you to take a coffee nap. 

2. It Could Be Sugar Crash

If you like your coffee to be sweet with whipped cream, extra sugar, honey, caramel, etc. then you could easily be hit by a sugar crash. 

What is a sugar crash? When you consume sugar more than the required amount, then the insulin levels rise up which causes your blood sugar levels to drop. As your BP decreases your energy levels go down. That’s the major reason why you feel tired after drinking coffee. You might also feel hungry, anxious, irritated, dizzy, or on edge because of a sugar crash.  

Another reason could be the sweet snacks you’ve been consuming with your coffee. As far as we know, coffee and cake make a good combination. People also have a habit of munching sweet puffs or biscuits with coffee.

3. Coffee Is a Diuretic 

It’s a known fact that caffeine is a diuretic for years. Meaning, it makes you go to the loo often. So, you might notice that drinking coffee can make you lose a lot of water, leaving you tired and cranky. 

Losing all that water reduces the fluid in the blood, which can affect your blood pressure. Coffee dehydration can lower BP, which can result in fatigue and sleepiness. 

Coffee also causes the blood vessels to narrow, which again reduces the activity of the body. So you might want to limit the consumption of coffee.  

4. You Could Be Immune to Coffee

Another reason why coffee makes you sleepy could be you getting immune to caffeine. If you are a regular drinker, then the effects of coffee won’t affect you anymore. This can happen easily with the increased intake of coffee. 

According to a study, when you regularly consume coffee, you can develop a tolerance for it. If you notice the same issues with you, what you can do is cut off caffeine for a few days to regularise your body functions. 

5. Your Body Is Affected Differently by Coffee 

Yes, it’s true. Not everyone feels charged after having coffee. As mentioned earlier, coffee affects people differently. While some might say “coffee makes me anxious” others might experience nausea after coffee. 

Some might not be able to sleep after having it while some can just doze off! This happens due to the different metabolism and functioning habits people have. And to be honest, this is more of a try-and-know-it-yourself case. So, the next time you feel sleepy after coffee, try noticing if it always happens.
