Why Does Coffee Make Me Sleepy?

Can Coffee Make You Sleepy?

Yes, it can make you sleepy. 

In the world, along with herbal teas, coffee is one of the most popular stimulants. Many turn to the beverage for more energy, attention, and alertness. In rare instances, though, it could have the reverse effect and leave you feeling exhausted, and sleepy.

Why Does Coffee Make Me Sleepy?

We’ll explore some of the several reasons why you can still feel exhausted even after a cup of coffee below. More significantly, we’ll also show you how to solve them.

Reason Coffee Make Me Sleepy

Timing of Consumption of Caffeine

Coffee makes certain people drowsy due to caffeine consumption time. Caffeine’s half-life is 4-6 hours. Caffeine stays in the body until late in the day, creating sleeplessness or weariness.

Late-day coffee might disturb the sleep-wake cycle and increase cortisol levels. Cortisol levels rise in the morning and decline during the day, helping regulate sleep-wake cycles. If coffee is consumed later in the day, cortisol levels may not normally decline, causing weariness or difficulty falling asleep.

Caffeine disrupts melatonin production, which regulates sleep. Evening melatonin synthesis induces drowsiness and aids sleep. If eaten late in the day, caffeine can disrupt melatonin production, making you drowsy.

Quantity of Caffeine Consumption

Quantity of Caffeine Consumption

Caffeine disrupts sleep, especially at high doses. An 8-ounce cup of coffee typically provides 95 milligrams of caffeine. Caffeine overdose can create anxiety, agitation, and fatigue as the body tries to balance its stimulating effects. To avoid disrupting sleep, caffeine should be controlled, especially before bedtime.

Individual tolerance

Genetics, age, weight, and health affect caffeine tolerance. Even modest doses of caffeine might cause drowsiness in sensitive people. Caffeine tolerance can also rise, requiring more caffeine to have the same effects. Caffeine tolerance affects sleep and well-being, therefore people must pay attention to their bodies.
A 200-pound individual may feel tired after drinking a cup of coffee in the morning, but a 150-pound person may feel stimulated. This unique caffeine tolerance underlines the necessity to monitor one’s body’s response to caffeine and adjust consumption.

Coffee Prevents Adenosine

A neurotransmitter called adenosine is produced by the body naturally and contributes to weariness. Caffeine, which is consumed in coffee, enters the circulation and is transported throughout the body, including to the brain.

When caffeine enters the brain, it adheres to the adenosine receptors and prevents the brain from absorbing the chemical. Your body, however, continues to make it.

Consequently, your brain will be overloaded with the accumulated adenosine when you eventually come down from your coffee spike. As a result? You wind up needing to grab another cup of coffee because you’re so exhausted and sleepy.

Coffee Causes Urination

Coffee Causes Urination

You undoubtedly already know that coffee has natural laxative and diuretic properties, although you may not be aware of the latter. This implies that drinking coffee also causes frequent urination. 

According to studies, if you consume four or more cups of coffee or shots of espresso a day or more often, you may discover that you need to use the restroom more frequently than usual.

Your body expels fluids when you urinate. Dehydration may result from such a procedure. Coffee does provide your body with some water, but it’s debatable just how dehydrated you become from it. However, by often emptying your bladder, you run the danger of experiencing the side effects of dehydration, which might include feeling tired.

This happens because a deficiency in blood volume slows down circulation and raises the heart rate, which might leave you feeling lethargic or exhausted.

To prevent this, drink plenty of water. If you start to feel lightheaded or experience dry mouth or skin, drink plenty of water throughout the day and avoid caffeine. You should also eat meals high in water, such as fruits and vegetables.

Inferior Products

It’s common knowledge that you get what you pay for, and coffee is no different. Bottom-shelf coffee from your neighborhood grocery may include a blend of subpar coffee from Brazil or Vietnam, and “sub-par” is putting it mildly.

The Department of Public Hygiene in Lisbon, Portugal, conducted research and came to the conclusion that 91.7% of the coffee from Brazil had mold in it.

More research has connected mycotoxins, the dangerous chemicals produced by a fungus, to human chronic tiredness.

So it only makes sense that your body will respond poorly to the moldy coffee, leaving you exhausted and confused. Spend a little more money to make sure you’re getting coffee from reputed brands or farms to prevent this.

Coffee With Too Much Sugar

Coffee With Too Much Sugar

The majority of us appreciate a decent Starbucks peppermint mocha during the holidays and a chilly java chip frappuccino during the summer. These beverages are undoubtedly wonderful, but they are also incredibly high in sugar.

You may even claim that you are consuming a cup of sugar mixed with a little coffee. And if that’s the case, your grogginess could be caused by a sugar drop.

Your body processes sugar considerably more quickly than caffeine. Sugar crashes can occur for some people as soon as 90 minutes after taking the sweetener. You can feel tired when it leaves your system once it has completed its journey.

Other coffee components

Other substances in coffee can make you weary. Theobromine and theophylline, caffeine-related chemicals, can also sedate. These compounds increase caffeine’s sleep-inducing properties, making coffee drinkers sleepy. Consider these other chemicals while considering coffee’s effects on sleep and energy.

Poor Sleep Habits

Poor sleep habits might cause coffee-induced fatigue. Disrupted sleep patterns can lead to poor sleep and caffeine use. Caffeine’s effects can be amplified by this cycle. Cortisol, a stress hormone, can disturb the sleep-wake cycle and cause fatigue. Stress, poor sleep, and coffee all cause weariness.

How Can These Effects Be Reduced?

How Can These Effects Be Reduced?

There are a couple of things you may do to try to avoid feeling tired after drinking coffee.

  • Start with some general health recommended practices first, before anything else. Try to sleep in a comfy bed for at least 7-8 hours each night. This can help you feel less stressed, think more clearly, and focus better. All of these things will help you use caffeine less frequently.
  • Second, try not to overdo it, even if you require a caffeine boost throughout the day or just like the ritual of a cup of coffee. Doctors advise people to limit their daily calorie intake to four eight-ounce glasses.
  • Finally, remember to drink plenty of water. To avoid dehydration, make sure you’re drinking enough water in addition to your coffee. The Institute of Medicine advises males to consume 13 cups of water daily and women to consume 9 cups. That includes the water you get from eating, but drinking water will keep you hydrated the most.

Is It Bad To Sleep After Drinking Coffee?

Is It Bad To Sleep After Drinking Coffee?

Yes, drinking coffee before bed is not advised since it might disrupt your sleep and make it harder for you to fall asleep. Because caffeine is a stimulant, it might be challenging for your body to wind down and get ready for bed.

Caffeine can linger in your system for up to 6 to 9 hours after intake, according to research. There is a misconception that drinking coffee will keep you awake. Even after consuming coffee, you can fall asleep in five minutes or less, but the quality of your sleep suffers, which means it takes longer for your body to recover.

In addition to this, you may get severe headaches, neck pain, or back pain the next morning.

It is better to refrain from drinking coffee in the late evening or right before bed.

Coffee Makes Me Tired And Dizzy

As mentioned above, that’s probably because caffeine has the potential to be a diuretic, aiding in the removal of salt and water from the body.

If you drink coffee without being adequately hydrated, you could suffer the following symptoms of dehydration:

  • Confusion
  • Dizziness
  • Dry mouth and skin
  • Fatigue
  • Thirst

Make sure you’re drinking enough water along with your morning coffee to help prevent dehydration. In order to maintain sufficient hydration, people need to consume 92 to 124 ounces of water per day.

Which Make You More Sleepy: Coffee Or Tea?

Which Make You More Sleepy: Coffee Or Tea?

Tea can make you more sleepy than coffee can.

Because there isn’t much energy left to wake up, drinking tea while your body is already in need of sleep will make you feel tired almost instantly. Simply said, drinking tea speeds up the body’s natural transition from Yang (stimulation, activity) to Yin (recovery, sleep, relaxation).

That transition might occur so quickly when you are already exhausted that you may believe tea is actually making you fall asleep. However, this process is always indirect; the manner that tea induces sleep is mostly via Yang stimulation.


Why doesn’t caffeine give me energy?

You’ve Developed a Tolerance to Caffeine. Caffeine tolerance may be the cause of your inability to feel the energizing benefits of caffeine that it formerly did. At this point, your body has become accustomed to the quantity of caffeine you typically consume and will require more of it to get the same energy boost.

Why do I feel sleepy no matter how much I sleep?

Your large sleep debt or your lack of circadian rhythm compliance are the two most likely causes of your constant exhaustion, regardless of how much sleep you obtain. Additionally, being sick, pregnant, or suffering from a medical condition like anemia or diabetes might make you feel tired.

Why you shouldn’t drink coffee immediately after waking up?

If you want to stay attentive throughout the afternoon, getting your caffeine fix in the early morning might not be the greatest idea. If you drink your coffee directly when you get up, you could feel jittery and hyperaware straight away, and then quite exhausted a few hours later.

Sum Up

When you wonder “Why does coffee make me sleepy?”, keep in mind that it’s not the caffeine itself; rather, it’s how it affects your body. not getting enough sleep or water consumption? 

Caffeine will just make the situation worse. You might be able to get the most out of your daily cup of coffee if you first take care of your physical needs. If not, the coffee can make you feel exhausted because your body requires something else that caffeine can’t provide.
