Does your brain go back to normal after quitting caffeine?

Caffeine also boosts other hormones and neurotransmitters like adrenaline and dopamine, and reduces blood flow to the brain. The withdrawal symptoms happen as the brain works to adjust to functioning without caffeine. Fortunately, caffeine withdrawal does not last long and symptoms are considered to be relatively mild.

The duration of caffeine withdrawal symptoms vary from person to person, but caffeine withdrawal usually lasts at least 2 to 9 days . Someone who abruptly stops caffeine intake after regular use will usually feel withdrawal effects between 12 and 24 hours after stopping. The peak of withdrawal effects usually occurs between 24 and 51 hours. If you regularly consume caffeine, caffeine withdrawal will likely affect you at some point. The more caffeine you drink, generally the worse the withdrawal experience is. Habitual consumption of even just one small cup of coffee per day can produce withdrawal symptoms. How caffeine withdrawal symptoms happen Caffeine is a psychoactive stimulant that decreases drowsiness by blocking adenosine receptors. Adenosine is a neurotransmitter connected to the body’s sleep-wake processes. By blocking the receptors, caffeine can allow a person to experience a temporary, improved feeling of wakefulness. Caffeine also boosts other hormones and neurotransmitters like adrenaline and dopamine, and reduces blood flow to the brain. The withdrawal symptoms happen as the brain works to adjust to functioning without caffeine. Fortunately, caffeine withdrawal does not last long and symptoms are considered to be relatively mild. Are some people more prone to caffeine withdrawal? One 2014 study identified genes that affect a person’s response to caffeine metabolism. Researchers can use these genetic markers to predict the likelihood that someone is a heavy coffee user. This suggests that your coffee cravings may just be genetic! Caffeine withdrawal symptoms The more caffeine consumed daily, the more intense withdrawal symptoms tend to be. Symptom duration varies but might end between 2 and 9 days. Common caffeine withdrawal symptoms include: anxiety

cognitive effects

fatigue

headaches

mood changes Headaches Headaches are often associated with caffeine withdrawal. Headaches happen because caffeine reduces your brain’s blood vessels. This constriction slows cerebral blood flow. When you cease caffeine consumption, the constricted blood vessels expand. After you stop using caffeine, blood flow to the brain increases. Headaches are from the brain adjusting to the increase in blood flow. Once the brain has adapted, the withdrawal headaches will stop. Duration and severity of the withdrawal headaches vary. Tiredness Fatigue is another symptom of caffeine withdrawal. Caffeine improves energy and reduces drowsiness by blocking adenosine receptors. Adenosine is a neurotransmitter that can cause fatigue in some circumstances. Once caffeine is eliminated, many people feel tired and fatigued. While fatigue can be frustrating, allowing your brain’s neurotransmitters to stabilize should lead to more sustainable energy in the long run. Caffeine is quickly absorbed into the bloodstream and excreted through urine. Tolerance increases with use. This can lead to frequent use and dependency, and therefore a worsening of withdrawal symptoms. Mood changes Negative cognitive and emotional effects can also be a consequence of caffeine withdrawal. Caffeine stimulates the release of hormones adrenaline, cortisol, and epinephrine. Caffeine also increases the levels of neurotransmitters dopamine and norepinephrine. If you have developed a mental and physiological dependence on caffeine, you might experience feelings of anxiety, difficulty concentrating, and a depressed mood. This should only occur while your body is adjusting to the lack of caffeine. How to treat withdrawal symptoms Here are some tips if you want to decrease or quit caffeine: Taper consumption instead of going cold turkey. If you are used to drinking coffee, try half-decaf half-regular and gradually wean yourself off.
