How long does caffeine withdrawal last?

In this brief article, we are going to answer the question “how long does caffeine withdrawal last?”. We will discuss what are the signs of caffeine withdrawal and how withdrawal symptoms should be treated. In the end, we will understand how caffeine affects the body.

How long does caffeine withdrawal last? 

Caffeine withdrawal lasts anywhere from 2 to 9 days. Caffeine withdrawal symptoms commonly appear 12 to 24 hours after discontinuing consumption.

Although the time it takes for caffeine withdrawal symptoms to subside varies from person to person. 

The worst symptoms of withdrawal often hit somewhere between 24 to 51 hours after the start of the detox process.

If you drink caffeine on a daily basis, caffeine withdrawal symptoms will almost certainly strike you at some time. 

The severity of caffeine withdrawal is often proportional to the amount of caffeine consumed. Even a single tiny cup of coffee used regularly might cause withdrawal symptoms.

What are the signs of caffeine withdrawal?

The more caffeine that is ingested on a regular basis, the greater the likelihood that withdrawal symptoms may be severe. The time that symptoms last might range from 2 to 9 days.

Common signs of caffeine withdrawal include:

  • anxiety
  • fatigue
  • headaches
  • mood shifts
  • Headaches

There is a strong correlation between caffeine withdrawal and headaches. Your brain’s blood vessels dilate as a result of caffeine, which causes headaches. 

The restriction slows the blood flow to the brain. When you stop drinking coffee, your blood vessels relax.

When you quit using caffeine, your brain’s blood supply improves. The brain is having trouble adapting to the increased blood flow, which might cause headaches. When the brain adapts, withdrawal headaches will disappear. The withdrawal headaches range in length and intensity.


Another sign of caffeine withdrawal is fatigue. Caffeine’s ability to inhibit adenosine receptors is what gives it its energizing and wakefulness-promoting effects. One neurotransmitter that sometimes contributes to weariness is adenosine. When caffeine is removed, many individuals experience exhaustion and weariness.

While exhaustion might be discouraging, giving your brain’s neurotransmitters time to settle should result in longer-lasting vigor. The bloodstream absorbs caffeine fast, and it is then eliminated via the urine. As use grows, tolerance rises. 

Mood swings

Caffeine withdrawal has been shown to have a variety of negative consequences, including those on cognition and mood. adrenaline, cortisol, and epinephrine are all released when you drink caffeine. Caffeine raises dopamine and norepinephrine.

In the event that you have established a mental as well as a physiological reliance on coffee, you may find that you suffer from sensations of anxiety, have trouble focusing, and have a sad mood. This should only happen once your body gets used to not having any caffeine.

How should withdrawal symptoms be treated?

Here are some recommendations for reducing or giving up on caffeine:

Instead of quitting completely, reduce your intake. If you’re accustomed to drinking coffee, experiment with half-regular drinks and gradually cut down.

Be careful not to unintentionally reintroduce caffeine. Check the labels of bottled drinks like soda, gin, and tea, as well as foods.

It’s possible that dehydration might make your withdrawal symptoms much worse. Take a pain treatment that is available without a prescription, such as ibuprofen, or aspirin, if you are experiencing withdrawal headaches.

You may likely feel weary after you quit using caffeine, so sleep 7 to 9 hours every night to fight this.

How does caffeine affect the body?

Caffeine enters the circulation through the small intestine and stomach. Caffeine, after it has entered the circulation, activates the central nervous system, which includes the nerves, brain, and spinal cord, to provide the effect of feeling more awake and alert. 

Caffeine promotes attention and concentration while reducing weariness. Caffeine increases dopamine transmission in the brain when consumed orally. Dopamine is a neurotransmitter that aids in regulating movement, motivation, and emotions. 

When the signaling rises, you experience an increase in your level of alertness and wakefulness. Consuming a cup of coffee may have a noticeable impact on the body in less than 15 minutes. 

Caffeine levels peak around an hour later and remain stable for many hours. Six hours after consuming coffee, half of it remains in your body. Up to ten hours are needed to eliminate caffeine from your system.

If you have caffeine sensitivity, even little doses might make it difficult to fall asleep and leave you feeling anxious, restless, and with a fast heartbeat. Caffeine consumption of more than 600 mg per day is considered excessive by health and nutrition experts.
