The world runs on coffee. It is one of the most consumed drinks and many people claim that they can’t function without having their morning cup. 

Coffee offers a lot of benefits, including burning fats and reducing the risk of type-2 diabetes.

But more than that, people drink coffee to stay alert and awake. But what if you don’t feel the effects of caffeine anymore?

If you’re here, it is because you’re wondering, why doesn’t coffee wake me up? In this article, let’s explore the reasons why this happens.

Why Doesn't Coffee Wake Me Up

Built-Up Caffeine Tolerance

If coffee makes you stay awake before, but it doesn’t do that for you now, then you might have reached your coffee consumption limit.

Everything is good in moderation. When your body consumes too much caffeine in one day, your body will grow used to it.

As your caffeine tolerance builds up, your drink will not have that same wake-up effect it had before.

Dehydration

Remember to drink your water. Water is essential for your body and overall health.

Dehydration can cause lower blood pressure and leads to fatigue.

With dehydration you will feel tired and not even drinking coffee could wake you up.

Putting Too Much Sugar

If you like drinking your coffee with sugar, some milk, and other sugary condiments, you will likely experience a “sugar crash.”

This sugar crash will cause your blood sugar to spike as sugar floods your system. The sugar overpowers the caffeine.

And once the effect of the sugar is over, you will feel more tired and sleepy.

You Are A Fast Caffeine Metabolizer

Simply put, coffee doesn’t wake you up because you are not sensitive to caffeine.

There is an enzyme in the body whose function is to metabolize caffeine so you cannot fully experience the effects of caffeine.

The level of this enzyme is different for each person. So, if caffeine doesn’t affect you that much, it might be because you have a fast metabolism. You are a fast metabolizer!

Genetics

Low sensitivity to caffeine can be hereditary. If high metabolism runs in the genes, there isn’t much that you can do about it.

Even if you drink gallons of coffee, it will not give you that energy boost.

Medication

If you are taking some medication, this might explain why you don’t feel the effects of a cup of coffee.

Medicines can interfere with the way your body processes caffeine content and can reduce its effectiveness.

You Are Cheating On Coffee

Maybe you haven’t realized it yet, but a lot of energy drinks contain caffeine. If you like your soda and energy drinks, then you are slowly building your caffeine tolerance.

The solution to this is to cut down your energy drink intake. Check the packaging of every drink you consume to see if it contains caffeine.

You Are Already Too Tired

A cup of coffee is helpful, especially if you want to pull an all-nighter.

But if your body is already too tired, regular coffee could only do much.

Your adenosine levels rise during the day, and when night comes, you will feel tired as they have already settled in the receptors. And if you’re too tired to function, not even caffeine could keep you awake.

Lack of Sleep

Coffee is not an almighty drink that can overcome your lack of sleep.

If you haven’t been getting enough sleep for the past couple of days, your body will force you to rest.

Coffee will not work no matter how many drinks you down. In that case, it is better to go to sleep.

Brewing Method

While the way you make your coffee does not affect how caffeine works, it might cause some change in the amount of caffeine that goes into your cup.

If you were used to using an espresso brewer but changed to a drip-brew method, the coffee might not have the same boost.

Switching Coffee Brands

Different coffee brands contain different amounts of caffeine.

If you think coffee doesn’t wake you up anymore, it might be because you switched brands and the one you have lower caffeine content. 

Here’s a funny clip on “What really happens when coffee doesn’t work.”

Coffee Alternatives to Wake You Up

If you think coffee isn’t working for you anymore, there are other things you can do to keep you alert and active.

  • Alarm Clock: It’s not as flavorful as your cup of coffee. But if you want to stay awake, you can set several alarms to go off every 15-30 minutes or so to jolt you out of your sleep.
  • Chewing Gum: Chewing gum can increase the blood flow to your brain and fire up your nervous system to keep you awake.
  • Tea: If your coffee isn’t working, switched it with energy-boosting teas such as matcha. It has a specific amino acid that will keep you alert.

Final Thoughts

If you’re here, then now you know why caffeine doesn’t work on you. But instead of dwelling on why, just enjoy your flavorful coffee and try out different ways to still be functional even without your favorite cup of joe.

Keep your body active and stimulate your mind. Do some exercises, chew some gum, drink more water, and get enough sleep. If you are healthy and well-rested, you will not have any trouble staying awake and alert.
