Why Drinking More Coffee Can Make You Feel Tired & How To Avoid It


As a regular coffee drinker, you know it..

The day has not really begun until you have your first cup of coffee..and another one later..and then another one..

It won’t be long until your haggard look starts to show and you start crashing..

“but hey, shouldn’t coffee make me feel more energetic?”

Well yes and no..technically caffeine is a psychoactive substance that supposedly help to keep you awake when you feel tired. It blocks the action of adenosine by inhibiting the adenosine receptors found in the neuron endings of the brain. As a result, adenosine molecules start to accumulate..

Over time, the caffeine in your body starts to get metabolized and the stimulant effect starts to wear off. Suddenly the excessive adenosine molecules begin to flood into your brain causing the receptors become saturated..and caffeine crash kicks in..

The more you drink, the more tired you become, and the more you need to drink..the cycle goes on and on like a positive feedback mechanism..this is the reason why you feel more tired even after drinking a few cups of coffee as opposed to giving you the energy you need to keep the day going. Ultimately, it is the binding action of adenosine molecules that makes you feel tired and sleepy and unable to concentrate.

It is important to know that coffee exhibits diuretic property, it draws water out from your bloodstream an causes you to become dehydrated. Insufficient water intake certainly contributes to making you feel more tired than you already are.


1.) Get enough rest

Without having adequate sleep, the adenosine level in your brain is higher than it normally is to begin with. This increases the chances of crashing after your first cup of coffee.

2.) Stay hydrated

Since caffeine has the ability to promote diuresis and make you feel fatigued , it is best to keep yourself hydrated throughout the day. Besides that, water can also dilute the caffeine content and help to dissipate crashing effect as it sets in.

3.) Lower Your Caffeine Intake

Lowering your caffeine intake helps to prevent the surge of adenosine binding activity in the brain, therefore it can lower the chances of you crashing in the middle of the day. Scientists recommends a maximum 400mg of daily caffeine intake. The picture below will give you a clearer comparison perspective:



4.) Spread out your caffeine intake throughout the day

In case you find it difficult to cut down total daily caffeine intake, try evening out your caffeine consumption to allow a more steady stream of stimulant effect. Instead of adding 2 teaspoons of coffee powder, add only 1 teaspoon per cup of coffee and allow yourself to have 2 cups.

5.) Eat something

Although coffee does provide you an instant boost of energy, the empty calories will leave you feeling tired sooner than you have had a proper meal to go with the coffee. Your body needs to obtain real calories to function normally and the only way to achieve this is by eating real food. Apart from that, drinking coffee in an empty stomach might irritate your stomach lining leading to gastritis. If you haven’t read about my previous post on gastritis you can click here.
