Caffeine is one of the most widely consumed substances in the world. It is a psychoactive substance that stimulates the central nervous system, which causes wakefulness and increases alertness. Caffeine is also an ergogenic aid and competitive athletes often use it to improve their performance by delaying fatigue and reducing pain perception.
Since caffeine acts as a stimulant, stopping consumption can lead to withdrawal symptoms, including headaches, fatigue, drowsiness, decreased concentration, decreased alertness, and irritability. In this article, the amount of time for an individual to become tolerant to caffeine will be examined. The article will also discuss the symptoms individuals typically undergo when consuming too much caffeine and what steps can be taken to prevent tolerance from occurring.
What Is Caffeine Intolerance?
Caffeine is a common ingredient in many dietary supplements and beverages such as coffee, tea, soft drinks, and energy drinks. According to the National Institute on Drug Abuse, approximately 80% of adults consume caffeine each day. Caffeine is also found in chocolate, some herbs, pain relievers, and medications. When people consume too much caffeine, they may experience nervousness and irritability, followed by fatigue and anxiety.
How Does Caffeine Work?
Caffeine in its pure state is a bitter crystalline powder that is found naturally in the coffee bean, cocoa bean, tea leaf, and cola nut. It also occurs naturally in foods such as oranges, berries, and apples. For caffeine to affect the body, it needs to be metabolized. The majority of caffeine molecules are readily absorbed by the gastrointestinal tract and enter the bloodstream. This causes feelings of physical stimulation characterized by increased alertness. Caffeine is then naturally metabolized and excreted from the body.
Caffeine is a stimulant that causes a person to feel alert and awake. It also causes dopamine release in the brain, which keeps people engaged, focused, and motivated.
Caffeine is also found in dietary supplements such as energy drinks. It is claimed that caffeine can improve performance in the gym and on the athletic field. Caffeine is also found in prescription medications such as pain relievers. These medications contain small amounts of caffeine to offset drowsiness and increase alertness.
What Is Caffeine Use Disorder and How to Cure It?
Abuse of caffeine is most often manifested in addition to the substance. Caffeine use disorder is a subtype of substance use disorder that is characterized by compulsive use of caffeine. To assess a person’s health, their symptoms must meet certain criteria. For example, individuals may be diagnosed with this condition if they consume caffeine in amounts significantly higher than an average person. Caffeine use disorder can, in severe cases, lead to physical dependence. In this case, the individual will experience withdrawals when they try to stop using caffeine. The symptoms of caffeine withdrawal include headaches, lethargy, irritability, and muscle pain. Stopping caffeine use can also lead to a decrease in the amount of dopamine released in the brain. This may lead to feelings of depression and anxiety.
The American Psychiatric Association does not recognize caffeine use disorder as a legitimate health condition. However, researchers have proposed criteria that would allow for its inclusion into the diagnostic manual. This could potentially include caffeine abuse as a type of substance use disorder. It is believed that this disorder can lead to a similar condition to alcohol or tobacco dependence.
Symptoms of Caffeine Tolerance
Caffeine tolerance often leads to fatigue because as the body becomes tolerant to caffeine, it takes more and more caffeine to produce the same energy boost.
As an individual becomes more tolerant to caffeine, they will also find themselves becoming drowsy if they do not consume it in large doses. Tolerance can cause a person to become fatigued after just one cup of coffee.
A study at the University of Washington showed that an individual’s risk for caffeine-related headaches is more than doubled when consuming more than 400mg/day of caffeine.
Caffeine tolerance can cause individuals to become irritable because they are not providing their bodies with enough energy. Instead, the body is forced to process high amounts of caffeine for energy.
Caffeine tolerance can cause an individual to have nausea because the body can no longer process the caffeine and absorb it properly.
What Happens When Your Body Becomes Tolerant
Caffeine does not alter the perception of fatigue or pain, but it does increase the ability to cope with both. It changes the levels of dopamine and adenosine in the brain, which results in increased energy and motivation. Brain cells that release dopamine are blocked by caffeine. However, they can still make their way from the cells if you consume a high dose of caffeine.
Ways to Reset Caffeine Intolerance
1. Slowly Reduce The Amount Of Caffeine Consumption.
If you consume caffeine regularly, you may develop tolerance. Your body can become more accustomed to this habit and require a higher dosage of caffeine to produce the same effect. For example, for you to get the same effect as coffee, you would need to consume 140 cups. Your body may not be able to tolerate this much caffeine, so cut back slowly by only drinking 1 cup per day until the desired results no longer occur.
2. Changing Diet
You can also reduce caffeine intake by changing your diet gradually. Drink herbal teas or coffee substitutes instead of coffee, and drink decaffeinated tea or soft drinks instead of caffeinated beverages.
You can also reset caffeine tolerance by resting/relaxing/sleeping. As the body is more comfortable, it starts producing body chemicals that are less sensitive to caffeine. This is why you may want to take a total of 1 week off from drinking caffeinated drinks and focus instead on consuming herbs that do not contain caffeine.
How Long Does It Take To Reset Caffeine Intolerance?
Caffeine is a drug that stimulates the central nervous system of humans and animals, and it can cause dependence among chronic users. Despite this, there is no clear evidence that tolerance develops among regular users.
The first signs of withdrawal occur eight hours after stopping caffeine intake. However, a further increase in withdrawal symptoms occurs between 12 and 48 hours, and peak levels of fatigue are reached 72 hours without it. For healthy people who do not drink coffee or energy drinks, tolerance normally develops in four to six weeks but could take up to one year for heavy caffeine users.
Symptoms of Caffeine Withdrawal
A person who decides to stop consuming caffeine can experience numerous symptoms. Initial symptoms can be insomnia, fatigue, depressed mood, and decreased motivation. However, symptoms tend to resolve within one week of stopping the consumption of caffeine.
Why Should You Reset Your Caffeine Tolerance?
When caffeine tolerance occurs, the body becomes accustomed to a higher level of stimulation. The body will require more and more caffeine to produce the same effects. The body can become dependent on caffeine if they do not consume enough food or water throughout the day. If you try to stop consuming caffeine, it can interfere with your circadian rhythm and cause severe fatigue. Caffeine is a stimulant, and it can also cause the body to quickly excrete water. Therefore, you may want to consume caffeine while drinking enough water to avoid dehydration.
Recommended Dosages of Caffeine
A cup of coffee contains about 95-300mg caffeine, an 8 oz. glass of cola has 150-175mg, a small cup of tea contains 5-6mg, and a can of energy drink contains 250-400mg. Caffeinated energy drinks are particularly dangerous because the caffeine in such drinks is combined with other harmful ingredients that can affect an individuals’ physical and mental health over time.
Caffeine Tolerance vs. Caffeine Allergies
Caffeine tolerance often ends up being confused with caffeine allergies. While an allergy to caffeine can result in abdominal pain, fatigue, and headaches, it is fairly rare. Caffeine allergies are uncommon because the body has tolerance receptors that create an immune response when they detect a harmful substance after the first exposure. Even though this immune response will not cause problems, the first time an individual consumes caffeine, it may cause a reaction if it is consumed again.
Tips on Making Coffee Tolerance Easier
Taking supplements such as 5-HTP, L-Tyrosine, or Huperzine can help to ease the effects of caffeine withdrawal.
2) Adequate sleep
Sleeping well will help you to stay calm and stress-free. This will make avoiding the urge to have caffeine.
Exercising for at least 20-30 minutes a day helps release stress and reduce the effect of caffeine on the body. It also helps to burn unwanted fat that might be causing you to feel sluggish.
4) Drink more water
Drinking adequate amounts of water throughout the day can help boost your energy and reduce the desire to have caffeine.
5) Quit smoking
If you regularly smoke and consume caffeine to keep off a nicotine craving, consider quitting both. The chemicals found in cigarettes can interfere with the absorption of caffeine in your body.
4) Stay hydrated
Caffeine can increase dehydration, so staying hydrated will help counteract caffeine withdrawal effects.
5) Caffeine Withdrawals
Caffeine withdrawals will usually clear up within one week after stopping caffeine consumption, but it is impossible to achieve 100% tolerance resets.
Caffeine in Coffees
1) White Coffee
Although coffee contains caffeine, the caffeine in brown coffee is generally much stronger than in Espresso. White coffees have less caffeine than black coffees do. The specific amount of caffeine varies greatly depending on the brand. Most products, however, contain around 5–10 mg per serving.
2) Dark Roast Coffee
Dark roasts are roasted longer and less course than light roast and medium roasts, producing a sweeter flavor. Dark roasts are also lower in caffeine.
3) Decaffeinated Coffee
Coffee beans are roasted and ground into a powder with the caffeine content removed; then, coffee is prepared with the decaffeinated beans. Decaffeinated coffee has a low quantity of caffeine compared to regular coffee and can still provide an energy boost.
4) Instant Coffee
Instant coffee is made from whole coffee beans that are finely ground to a powder, then processed through a special brewing process. This produces instant coffee that tastes much stronger than regular brewed coffee.
Espresso is made with steam pressure forced through finely-ground coffee beans, producing a potent coffee extract often served in a small glass cup. Espresso contains approximately 50% less caffeine than regular coffee and an average of 0.7 mg/ml, depending on the variety of beans used.
All forms of caffeine are addictive if consumed in large amounts. Tolerance can develop quickly, so it is best to consume caffeinated beverages in moderation. Those looking to reset their caffeine tolerance may also want to consider cutting back on their intake slowly and going through a withdrawal period instead of simply cutting back or quitting.
Q: Why is it so hard to quit caffeine?
A: Due to its stimulant effects, caffeine has addictive qualities. And while most people are not addicted to coffee, they may drink caffeine beverages in excess.

Still, at the same time, it can cause many adverse side effects such as insomnia or headaches.
Q: Are there any foods that will help me to reset my caffeine tolerance?
A: Food can help restore your body’s ability to process caffeine. There are certain foods and nutrients, including B vitamins, vitamin C, L-Tyrosine, and carbohydrates, that can help with the process of resetting your tolerance.
Q: Are there any health benefits of caffeine?
A: Caffeine has many positive health benefits, such as improving memory and focus, reducing inflammation, and increasing endurance. However, it can also cause negative side effects such as anxiety or panic attacks.
Q: How can I minimize the effects of caffeine withdrawal?
A: When you stop consuming caffeine, you may experience negative physical and emotional symptoms during withdrawal. These symptoms include headaches, irritability, depression, lethargy, fatigue, and nausea.
Q: What is the best way to quit caffeine?
A: The best way to quit caffeine is to slowly reduce your intake until you no longer consume it. It is also important to go through a withdrawal period before you stop consuming it so that your body adjusts and you will not experience too many withdrawal symptoms.
