Coffee Makes Me Tired


Given that coffee contains lots of caffeine and is hence a stimulant, many coffee lovers will take it to get an energy boost and stay alert.

Consequently, it comes as a big surprise to many coffee drinkers when they end up feeling tired after taking coffee which is the opposite of what they wanted.

But, does coffee really make you tired? The simple answer here is yes, coffee can make you feel even more tired than you were before taking it. There are several reasons why this happens and perhaps knowing them and some ways to work around them will help ensure you get the most out of your cup of java.

However, before we get to why coffee can make you tired, it is important to note that coffee will react differently to different people. While some people will start feeling tired after the first cup, others can drink several of them without feeling any ill effects.

Why Coffee Can Make You Tired

If you tend to experience tiredness or drowsiness every time you take a cup or more of coffee, the following are the best explanations for this.

1. Coffee is a Diuretic

Just like alcohol, coffee is a diuretic beverage, and what this simply means is that it will make you pee a lot. If you are one of those hardcore coffee drinkers that only take coffee and little to no water you are likely to get dehydrated.

The dehydration, in turn, makes you feel sluggish and tired. For typical coffee drinkers, this is enough reason to want to grab one more cup of coffee not knowing that this then creates a vicious cycle of dehydration that leaves you feeling more tired when you take your coffee.

2. It Interferes with Your Wake Cycle

While coffee might keep you awake and alert as you try to finish that important assignment or project, it can also interfere with your body's natural sleep-wake cycle.

The caffeine in coffee suppresses adenosine which is a chemical in the central nervous system tasked with controlling the sleep cycle, but it does not stop its production. As the effect of caffeine on your body wear up, you end up with excessive amounts of adenosine which wants to bind with the adenosine receptors in the brain but cannot due to the excess amounts, and so you will suddenly feel exhausted.

3. You Drink Cheap and Low-Quality Coffee

The kind of coffee that you drink might also be contributing to the tiredness that you feel after taking your daily dose of caffeine.

Cheap and low-quality coffee often leads to higher levels of mycotoxins in your cup than you would get when drinking good quality coffee. When your brain is exposed to the high volume of mycotoxins, feeling drowsy or getting brain fog will be some of the side effects.

4. There is Too Much Sugar in Your Coffee

For the coffee lovers with a sweet tooth, you might be tempted to sweeten your coffee with sugar and other sweeteners. But, if you end up feeling tired after drinking it what you might not know is that it is not the coffee that is causing the tiredness but the sugar.

Sugar is used up and processed by the body faster than the caffeine, and so once all of it is used up you are likely to experience an energy slump that is what leaves you feeling tired. However, how quickly this happens will vary from one person to the other and some people might not even notice the energy slump.

But, the good news is that there are many things that you can do and the following are the most effective ones.

1. Add Less Sugar to Your Brew

Better yet, you can also use other natural sweeteners like honey or even cinnamon.

If you drink more than 2 cups of coffee you are more likely to get dehydrated due to the diuretic nature of caffeine.

3. Limit your Consumption to Morning Hours

Drinking your coffee in the morning can help limit the effects of caffeine on your sleep cycle and this, in turn, can help ensure you do not end up feeling tired.

4. Drink Plenty of Water

While coffee is mostly water, its diuretic properties will make you pee a lot, and so to ensure you do not end up dehydrated which also cause the tiredness, you should drink lots of water. Drinking a lot of water can also help to flash out some caffeine from your blood.


Most adults cannot go a day without taking coffee because for most it is the fuel that gives them the energy they need to face the day and helps keep them alert. However, it can sometimes do the opposite by leaving you feeling tired.

There are different reasons why coffee can make you tired from taking too much of it to adding lots of sugar and also because of the diuretic nature of caffeine.

But, the bottom line is that if you want to get that punch that coffee can provide without ending up tired, you should take it moderately and not abuse it.
