TL;DR If you often find yourself yawning after your cup of joe, then two things may be happening - caffeine crash or caffeine hangover. This article will introduce these two concepts plus other bonus reasons why, and how you can prevent them from happening.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Caffeine is a surefire way to keep you awake, right?
Wrong.
While caffeine can help keep you awake, it could also go the other way.
Just as when you need your caffeine fix to pull yourself out of misery – aka midday slump – the opposite happens. You pass out. You wake up. Lo and behold - your face is on your office keyboard!
As a stimulant, caffeine’s supposed to perk us up right?
But why does it make us feel tired instead?
In this article, we’ll introduce two concepts that could probably explain why it happens to you, and how you can prevent that from happening.
When you start feeling like your soul is leaving your body post-caffeine, you’re not going through transcendence. Just one of these two phenomena is happening:
Caffeine crash
A caffeine crash happens after taking in moderate to high dose of caffeine. Basically, it’s that moment when you feel like you’ve run a few miles after your first cup of coffee and feel like going back to bed (twist: you don’t really run).
Curious what happens behind-the-scenes? Here it goes:
“Caffeine has been associated with enhancing the ability to perform mental tasks and elevate feelings of energy, however, a single dose of caffeine typically induces only 90-120 minutes of increased alertness and is often associated with an acute “crash” state following its metabolism.”[1]
Caffeine hangover
Believe it or not - this is a thing!
Caffeine hangover is like waking up with a bad hangover from downing bottomless cups of joe.
It happens after shocking your system with one too many cups of coffee or tea and your body just can’t keep up with the caffeine rush. You then go through the usual signs of a hangover - the feeling of being too tired and lazy to move, with nausea and vomiting to boot.
If you’re curious about what causes caffeine crash, Healthline has put together a list of the main reasons for “crashing.” [2]
Adenosine build up
To get some background, let's review for a minute from this article how caffeine keeps us awake.
Caffeine blocks adenosine, the sleep-inducing molecule in your body that causes sleepiness, from binding into its receptors. As an “adenosine receptor antagonist,” caffeine binds into the receptors so it blocks adenosine and inhibits the latter’s effects on your body.
While this all happens, the body continues to produce adenosine, which awaits its turn to bind to the receptors. This causes adenosine build up. When caffeine’s effects wane, the excess adenosine finally binding into the receptors causes the feeling of exhaustion.
Caffeine is a diuretic
We’ve found out in the article “Does coffee dehydrate you?” that caffeine is a diuretic. In non-scientific, everyday terms, it means that caffeine makes you pee more.
How does this make you feel tired and sluggish, you ask.
When you make a trip to the bathroom, you lose water in the body, which then reduces the amount of fluid in your blood. This means that being dehydrated causes your heart to beat faster and makes your blood pressure lower - exactly the reasons why you feel fatigued.
Sugar rush leading to sugar crash
If drinking black coffee is not your cup of tea (pun intended), then you’re likely to add in a little bit more sugar, honey and cream to your java fix. Going a little extra on your coffee may cause you to go through a sugar rush, and after a few more minutes/hours, a sugar crash. That’s when you go from a bubbly hero to a sleepy zero.
It’s easy to spot a caffeine crash and hangover. When you see the supposedly positive and desired effects of caffeine going south, then you’re in for some trouble. Specifically, the symptoms may go from being extremely exhausted, unable to focus, irritable and not in the mood, and just slumping back to bed or on your office desk (NSFW, like literally).

Careful about falling asleep at work or you could become an Internet meme like this poor fellow.
Unless you work outdoors or indoors in a job where you are physically active all day, it can be difficult for some people who have desk jobs to stay awake at work without caffeine.
Maybe the most important thing you can do to make sure you don’t nod off at work is to get a good night of sleep, at least 7 to 8 hours, at a regular time every night. Boredom can also cause you to nod off. Other than getting a good night’s sleep and having a fascinating job, there are things you can do to stay awake.
How do investment bankers stay awake on their 18-hour shifts?
Investment bankers work such long hours that many resort to chemical stimuli. There have been rumors of methamphetamine and cocaine use among investment bankers to burn the midnight oil. Other investment bankers take Ritalin or Adderall, which are given to children with ADHD but which are stimulants for adults. But the mainstay is probably coffee, energy drinks, and other concoctions containing caffeine.
Some law students spend 60 hours a week studying. Those who’ve been through law school advise prospective students to leave the Xbox at home so they’re not tempted with potentially ruinous distraction. How do law students get energy to study so much?
One thing many law school students do not do is party and socialize a lot. This has a doubly salutary effect because the time spent not partying is time they can spend studying. And then they are not out of sorts, hung over or over-tired the next day from partying.
