Does caffeine cause anxiety?

Caffeine is a central nervous system stimulant, and consuming too much can lead to symptoms of anxiety.

Caffeine is the psychoactive drug that people consume the most in the world. It is the second most consumed beverage after water, at 1.6 billion cups per day.

A survey conducted in the United States reports that approximately 85% of the population drinks at least one caffeinated beverage every day.

While many people drink caffeine to help them “wake up” and to stay alert, too much caffeine can have a negative effect on people, leading to numerous side effects, including some symptoms of anxiety disorders.

An anxiety disorder is a mental illness in which a person is overwhelmed with feelings of fear and uneasiness that interfere with daily life. The National Institute of Mental Health (NIMH) estimates that 31.1% of all adults in the U.S. will experience an anxiety disorder at some point in their lives.

Readers should note that there is a large distinction between having a formal anxiety disorder and feeling some symptoms similar to anxiety that may be worsened by drinking coffee.

Keep reading to learn more about the connection between caffeine intake and anxiety, including the symptoms, as well as how to consume caffeine safely in order to avoid triggering or worsening anxiety symptoms.

A literature review describes the many effects that caffeine has on the body. One of its main mechanisms of action is to block adenosine receptors, causing increases in dopamine, noradrenalin, and glutamate. In the cardiovascular system, this increases a person’s blood pressure and heart rate. In the central nervous system, lower doses of caffeine can improve motor activity and alertness, while higher doses can produce symptoms of anxiety.

Evidence from genetic studies found that adenosine receptor genes play a role in the development of anxiety. This suggests that some individuals may have an increased risk of anxiety disorders and that caffeine may make them more susceptible. More studies are needed in this area.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, recognizes caffeine-induced anxiety disorder as a condition in which caffeine interferes with daily functioning. To meet the criteria for this diagnosis, a person must have symptoms of anxiety directly caused by the consumption of caffeine.

The DSM-5 has also proposed criteria for caffeine use disorder, in which all three of the following criteria must be met:

persistent desire or unsuccessful effort to control caffeine use
use of caffeine despite harm
symptoms of caffeine withdrawal

Although this is not yet an official DSM diagnosis, it provides researchers with a framework to conduct further studies.

The symptoms of overuse of caffeine and the symptoms of anxiety can overlap.

Symptoms of using too much caffeine include:

nausea
dizziness
dehydration
headaches
restlessness
rapid heartbeat
insomnia
anxiety

Symptoms of anxiety typically include:

feelings of fear, dread, and uneasiness
excessive worry
sweating
restlessness
tenseness
rapid heartbeat

Overuse of caffeine can cause anxiety symptoms, and on the flip side, symptoms of anxiety may become worse with the use of caffeine. If a person is concerned about their coffee intake, they should speak with a doctor.

Studies show that there are health benefits of moderate doses of caffeine. Some of these benefits include improvements in mental alertness, concentration, fatigue, and athletic performance. Other benefits may include weight loss, lower risk of diabetes, reduced risk of Parkinson’s disease, and reduced risk of cancer.

The FDA issued guidance in 2012 stating that for healthy adults, caffeine consumption at less than 400 mg/day is not associated with adverse effects.

Results from a 2014 survey in the U.S. found that for all ages combined, the average intake of caffeine from all beverages is 165 milligrams (mg)/day. This is about the amount in 1–2 cups of regular coffee. The FDA state that any intake up to 400 mg of caffeine a day should not lead to adverse health effects. This is equivalent to about 3–4 cups of coffee.

Some groups of people, or those with certain health conditions, should talk with their doctor to determine if they should limit or avoid caffeine. These include people who:

are pregnant
are breastfeeding
have insomnia
experience migraines or chronic headaches
have anxiety
have stomach disorders such as ulcers
have an irregular heart rate or rhythm
have high blood pressure
take certain medications including stimulants, some antibiotics, asthma medications, and heart medications
are children and teenagers

Health and regulatory agencies have cautioned about the use of caffeine in these populations.

Of particular concern is the popularity of energy drinks in young people, with their high levels of both caffeine and sugar. There are also concerns about the effects of combining alcohol and caffeine.

The best way to provide more information about safe levels of consumption of caffeine needs to be determined.

The first step in making informed decisions is for a person to be aware of the caffeine content of beverages. Label reading and daily planning can help avoid the adverse consequences of excessive caffeine consumption.

People who want to reduce or limit their caffeine consumption should do so gradually. This will help avoid symptoms such as headache, fatigue, irritability, drowsiness, difficulty concentrating, and nausea.

The caffeine content of beverages was measured in the 2014 survey cited above. The investigators grouped them into several general categories:

Beverage	Caffeine Content (mg/fluid ounce)
Regular coffee	4-21
Espresso	47-63
Decaffeinated coffee	0.25
Carbonated soft drinks, caffeinated, regular or diet	2-7
Tea, caffeinated, regular or diet	1-8
Energy drinks	3-20
Energy shots	40-70
Chocolate milk	0.2-2

It is important to note that there were limitations in determining the amount of caffeine in the beverages included within the table. The study authors state that while most commercially available drinks have caffeine content listed on the label, for teas and coffees that are made to order, the content can vary widely. The caffeine content can depend on the origin of the crop, processing, and preparation.

Many people rely on the jolt of energy that caffeine provides to get them going in the morning. This can sometimes come with negative consequences, such as development or worsening of anxiety symptoms.

Decaffeinated coffee or tea may be a good alternative for many people. These beverages tend to have a similar flavor, however, they may not provide the energy boost that caffeine does. Once a person successfully weans themselves from caffeine, however, these can be a calming choice.

There is a vast array of herbal teas available. They are popular throughout the world and have numerous health benefits.

Some people find that exercise can be a great way to start the day. A walk or run outside, or a jog on the treadmill indoors, can be a good way to get blood flowing and clear brain fog. Drinking water can also help people wake up.

There is an association between the overuse of caffeine and anxiety. The effects of having too much caffeine can mimic symptoms of, or worsen anxiety.

People who experience caffeine-induced anxiety should avoid or reduce their consumption of caffeine.

It is important to be aware of the caffeine content of many commonly consumed beverages. With careful planning, people can make informed choices to reduce or avoid the use of caffeine.

Caffeine can sometimes cause effects similar to symptoms of anxiety, including nervousness and a fast heart rate. If you have too much, you may also get caffeine-induced anxiety.

Caffeine is the most popular and widely-used drug in the world. In fact, 85 percent of the U.S. population consumes some every day.

But is it good for everyone?

According to the National Institute of Mental Health, about 31 percent of U.S. adults will at some point in their lives experience an anxiety disorder. Does caffeine affect — or even cause — anxiety?

There is an association between caffeine ingestion and mental health.

In fact, the Diagnostic and Statistical Manual of Mental Disorders (DSM–5) — the guide published by the American Psychiatric Association and used by healthcare professionals for the diagnosis of mental disorders — currently lists four caffeine-related disorders:

caffeine intoxication
caffeine withdrawal
unspecified caffeine-related disorder
other caffeine-induced disorders (anxiety disorder, sleep disorder)

A 2008 study showed how caffeine increases alertness by blocking a brain chemical (adenosine) that makes you feel tired, while at the same time triggering the release of adrenalin that’s known to increase energy.

If the amount of caffeine is high enough, these effects are stronger, resulting in caffeine-induced anxiety.

While there are mental benefits to caffeine, high doses are known to induce anxiety symptoms, and people with panic disorder and social anxiety disorder are especially sensitive.

A 2005 study noted that excessive caffeine consumption can lead to symptoms similar to psychiatric conditions including sleep and anxiety disorders, increasing hostility, anxiety, and psychotic symptoms.

According to Harvard Medical School, caffeine use can mimic symptoms of anxiety.

The caffeine-induced symptoms that can mirror anxiety include:

nervousness
restlessness
trouble sleeping
fast heart rate
gastrointestinal problems

If you’re accustomed to regularly consuming caffeine, and abruptly stop, you can experience withdrawal symptoms, such as:

headaches
anxiety
fatigue
depressed mood
difficulty concentrating
tremors
irritability

Caffeine withdrawal is not considered dangerous like withdrawal from opioids, but it can be difficult and distressing.

Consider talking to your doctor for suggestions on how to cut back gradually, including getting enough sleep and exercise, and staying hydrated.

The concentration of caffeine varies depending on the type of beverage, the quantity, and the brewing style.

Below are ranges of caffeine contents in popular beverages:

8 ounces of decaf coffee contains 3–12 mg
8 ounces of plain black coffee contains 102–200 mg
8 ounces of espresso contains 240–720 mg
8 ounces of black tea contains 25–110 mg
8 ounces of green tea contains 30–50 mg
8 ounces of yerba mate contains 65–130 mg
12 ounces of soda contains 37–55 mg
12 ounces of energy drinks contain 107–120 mg

According to the U.S. Food and Drug Administration (FDA), 400 milligrams a day, which translates to about 4 cups of coffee, typically doesn’t result in negative or dangerous effects for healthy adults.

The FDA also estimates that around 1,200 mg of caffeine can result in toxic effects, such as seizures.

When reviewing these figures, keep in mind that there are wide variations in different people’s sensitivities to the effects of caffeine and the speed they metabolize it.

If you take any medications, they may also be affected by caffeine consumption. Speak to your doctor if you have any concerns.

There’s an association between caffeine consumption and anxiety including caffeine-induced anxiety disorder. Yet, for most people, moderate caffeine intake is safe and may have benefits.

Cutting back or eliminating caffeine from your diet quickly can lead to withdrawal symptoms, which can also be anxiety producing.

If you feel that your anxiety is increasing due to caffeine, or it’s making you feel anxious, speak to your doctor about the right amount for you.

how it affects the body, why it is useful, whether it causes addiction

Caffeine affects several important body systems at once.

Usually its effect is only for our benefit, but in certain circumstances caffeine can be poisonous. If we are talking about a healthy adult, then caffeine in a dosage within 400 mg per day is rather beneficial for health. It is safer for pregnant women not to exceed the dose of 200 mg per day.

See a doctor

But remember: the responsibility for your health lies with you and your doctor. We don’t write prescriptions, we give recommendations. Relying on our point of view or not is up to you.

What is caffeine

Caffeine is a very interesting biological compound that brings many benefits to the plants that create it.

In tea leaves, cocoa beans and, for example, in guarana seeds, caffeine works as a bioweapon. It protects the plant from leaf-eating insect pests and from green competitors: when the plant sprouts, the caffeine from the seed enters the soil and makes it unsuitable for other plant species. But in the composition of flower nectar, caffeine rewards pollinating bees, encouraging them to return again and again. This increases the plant’s chance of producing offspring.

Caffeine works as a natural pesticide – Science

Caffeine in nectar improves memory in bees – Science

For us humans, caffeine can act both as bees and as insect pests – it all depends on the dose. The effect of the substance is due to the fact that caffeine is very similar to adenosine, a biologically active substance that plays an important role in the human body.

What is adenosine – Journal of Current Neuropharmacology

How does adenosine work in the body – International Journal of Molecular Sciences

All the energy in our body is stored in the form of molecules of adenosine triphosphate, or ATP, which consist of adenosine and three “tails” – residues of phosphoric acid. By unhooking these tails, ATP transfers energy to proteins. When the tails of the ATP molecule run out, only adenosine remains.

ATP needs time to “recharge”. And if too much adenosine accumulates in the body, it begins to bind to adenosine receptors, which are also found on brain cells – neurons. So the body receives a signal that it is time to rest.

The caffeine molecule is very similar in shape to adenosine. But caffeine does not transmit any signals, but simply plays the role of a stub for receptors. While caffeine occupies receptors, adenosine continues to accumulate in the body, but the brain does not know about it, so we do not feel tired.

When we drink a serving of coffee, caffeine is absorbed in the intestines in about an hour, enters the bloodstream and, along with it, enters the brain. In about two hours, the concentration of caffeine in the brain reaches its maximum, and it begins to occupy receptors. The more coffee we drink, the more adenosine receptors caffeine will occupy – and the stronger the invigorating effect will be in the end.

How much coffee Russians drink

The time during which caffeine will act on the body depends on how many cups of coffee a person drinks and on his genetic characteristics. On average, if a person drinks a cup of coffee at 9-11 am, the enzymes release most of the receptors from caffeine by about 10 pm. The adenosine accumulated during this time in the body will again begin to bind to its receptors, and the person will soon feel drowsy.

The graph shows that coffee gives the most energy two hours after we drink it

The enzymes responsible for the destruction of caffeine encode the CYP1A gene.

Individual Differences in Caffeine Metabolism – Reviews of Pharmacology

But different people inherit different forms of this gene from their parents. There are forms that code for fast-acting enzymes, and there are forms that code for slow-working enzymes. Therefore, some people are energized by coffee for the whole day, while others have almost no effect.

How caffeine affects the body

How caffeine affects the brain. If a person has had a good night’s sleep and feels good, caffeine at a dosage of 30 to 300 mg invigorates and speeds up reaction time even in a well-slept person. If a person does not get enough sleep, then caffeine reduces the adverse effects of lack of sleep: it helps to better assimilate information and make more thoughtful decisions. This is important, especially if a sleepy person has to drive a car.

However, caffeine does not appear to improve creativity. This was shown by an experiment in 2020, in which 80 people participated. Half of the volunteers took one placebo tablet each, and the other half took the same tablet containing 200 mg of caffeine. After that, they were asked to solve several problems.

Caffeine does not affect creative thinking and does not help find new ways to solve problems – Consciousness and Cognition magazine People who took caffeine were better at practical tasks, but they were no better or worse at creative tasks than people who took a placebo.

We still know very little about how regular caffeine intake affects brain health. However, we do have some evidence for caffeine. For example, 13 studies found that people who drank three cups of coffee a day had a 30% lower risk of developing Parkinson’s disease than those who never drank coffee.

Parkinson’s disease is a severe disease in which a harmful protein gradually accumulates in neurons. It occurs in 120 people per 100,000 people.

What is Parkinson’s Disease – MSD Medical Handbook

However, it is too early to count on a protective effect of coffee. It was only identified in studies where scientists simply observed people who either drank or did not drink coffee or tea. More rigorous studies are needed to prove that caffeine, and not some other factor, provides protection.

Approximately the same situation with Alzheimer’s disease. Four observational studies have found that coffee and tea drinkers are slightly less likely to get sick than non-drinkers, but this remains to be confirmed.

But it is not yet clear how caffeine affects mental illness. Some research suggests that the relationship between mental disorders and caffeine is negligible.

However, a study in which scientists followed 50,000 American women for ten years found that women who drank 2-4 cups of coffee a day had less depression than those who drank just one cup a day.

Caffeinated coffee and the risk of depression in women – Journal of the American Medical Association

How caffeine affects the heart and blood vessels. Both the heart and blood vessels have receptors for adenosine. By binding to them, adenosine slows down heart contractions. And since caffeine prevents adenosine from slowing down the heart rate, for a long time scientists suspected that even a small amount of caffeine could disrupt the rhythm of the heart, that is, cause an arrhythmia.

The effects of caffeine on the heart have been studied since at least 1988 years old. However, it has not been possible to prove that caffeine in safe dosages causes arrhythmia in healthy adults.

Caffeine does not cause arrhythmias – Uptodate

Caffeine raises blood pressure in unaccustomed people – four robust studies from Uptodate

10 mmHg. But this is not harmful for health, because the pressure quickly returns to normal.

If a person starts drinking coffee or tea regularly, the body quickly gets used to caffeine and the pressure stops rising. So coffee lovers who do not exceed the recommended doses develop hypertension no more often than people who do not drink coffee at all.

Problems with heart rhythm can only occur in people who already suffer from cardiovascular diseases.

In people with high blood pressure, the same 250 mg of caffeine can increase blood pressure by more than one and a half times, and the older the person gets, the stronger the effect. That is why people with hypertension are advised to either completely give up caffeine or significantly reduce its use. This decision must be made with the attending physician.

How caffeine affects the endocrine system. There is a lot of evidence that women who drink more than two cups of coffee a day for years are less likely to develop type 2 diabetes than those who drink less than two cups.

Caffeine Protects Against Diabetes – Uptodate

Coffee, Caffeine and Type 2 Diabetes Risk – Journal of Cardiovascular & Metabolic Risk

Coffee consumption is associated with higher plasma adiponectin concentrations in women with or without type 2 diabetes – Journal of the American Diabetes Association

How to Prevent Type 2 Diabetes – MedlinePlus International Medical Guide

For example, this effect was revealed by a 10-year study in which scientists followed 88,000 American women who for years noted the amount of caffeine they consumed and came for examinations.

But why this happens, no one understands yet. Perhaps the reason is that caffeine increases the concentration of adiponectin in the blood. This hormone improves the sensitivity of cells to insulin, which means it prevents type 2 diabetes.

However, this has yet to be proven. So the authors strongly ask you not to count on coffee or tea as a means of preventing type 2 diabetes. For this, a balanced diet and an active lifestyle are better suited – in any case, these methods have reliable evidence of effectiveness.

Although other organs also have adenosine receptors, caffeine use does not appear to affect them in any way, according to the data we have.

Caffeine at recommended doses does not increase the risk of fractures, is not a diuretic, and does not cause any type of cancer.

How caffeine affects life expectancy. In 2014-2015, there was quite a bit of evidence showing that people who drink three to five cups of coffee a day are less likely to die prematurely from suicide and chronic diseases like type 2 diabetes and certain types of cancer.

Associating coffee consumption with all-cause mortality – Journal of Public Health Nutrition

In 2018, scientists analyzed data from more than half a million people and clarified that all people benefit from coffee, regardless of what form they got the CYP1A gene.

The benefits of coffee do not depend on the form of the CYP1A gene – Journal of the American Medical Academy

More recently, in 2020, Norwegian researchers analyzed the data of 117,228 women and confirmed their colleagues’ earlier conclusions: apparently, coffee does reduce the risk of premature death from chronic diseases. At the same time, there is still no explanation for this phenomenon.

When coffee can hurt. There are adenosine receptors on almost all organs, so caffeine affects the body as a whole, from the brain and cardiovascular system to the lungs and bladder. This effect can be negative, but only if too much caffeine enters the body.

Adults Can Take Up to 400mg of Caffeine – Dietary Guidelines for AmericansPDF, 30. 6 MB

dents StatPearls

It is believed that a person over 18 years of age without chronic diseases and pregnancy can consume 400 mg of caffeine per day without harm to health. This is the amount contained in 2-4 cups of coffee with a volume of 230 ml.

At the same time, a healthy person will not be poisoned by coffee or tea, even if he drinks more than four cups. Fatal poisonings have only been observed when people ingest about 10 grams of caffeine at a time. As a rule, this happens with an overdose of drugs and sometimes energy drinks. To get the same dose of caffeine from coffee, a person would have to drink about 20 liters of coffee per day.

However, everyone is different: some healthy people over the age of 18 are more sensitive to caffeine. Therefore, scientists and doctors recommend limiting yourself to 400 mg – this guarantees that there will be no problems, and the effect on health will remain purely positive.

But adult dosages of caffeine are not suitable for people under 18, pregnant women, and people with cardiovascular disease. You need to take this into account, otherwise you can inadvertently harm yourself.

Children and adolescents are lighter than adults and can be poisoned by an adult dose of caffeine, so it is safer not to use caffeine until the age of six. Children 6-12 years old with an average weight of 30 kg can absorb only 75 mg, and adolescents 13-17 years old with an average weight of 55 kg can absorb 137.5 mg of caffeine per day.

Regular doses of caffeine are also not suitable for pregnant women. If a woman regularly exceeds the allowable dose of caffeine for pregnant women, the risk of miscarriage and the likelihood that a child will be born with a low birth weight increase. Therefore, the American College of Obstetricians and Gynecologists advises pregnant women to consume no more than 200 mg of this substance per day.

Pregnant women can take no more than 200 mg of caffeine per day — Uptodate

Is caffeine addictive? However, not all psychoactive substances are drugs.

The Neurological Effects of Caffeine – Medscape

What Is Addiction – Bulletin of the American Psychiatric Association

Substance use causes the brain to release large amounts of the neurotransmitter dopamine in the nucleus accumbens sheath. This structure is considered the center of reward, that is, it is responsible for motivation and addiction formation.

Caffeine at recommended doses also releases dopamine. But this happens in another area of the brain – in the prefrontal cortex, which is responsible for attention and self-control, and does not participate in the formation of addiction. Therefore, caffeine in recommended doses does not cause narcotic cravings and does not cause problems for either the coffee lover or his relatives.

But if a person consistently exceeds recommended doses, they may develop a caffeine use disorder. In this state, a person really wants to reduce the use of this substance, but cannot.

What is Caffeine Use Disorder – Journal of Caffeine and Adenosine Research

People with this disorder are forced to consume more and more caffeine because the old doses wear off over time and the person feels bad without it. And people with this disorder have a higher risk of becoming addicted to a more dangerous psychoactive substance, such as tobacco or alcohol.

When attempting to abruptly stop caffeine use, about half of people will experience withdrawal symptoms: drowsiness, lethargy, headaches, nausea, and muscle pain. They usually start after 12 to 24 hours, become most severe after one to two days, and last up to nine days. But if you do not stop abruptly, but reduce daily doses of caffeine gradually – for example, over two to three weeks – withdrawal symptoms are almost not felt.

Over time, sensitivity to caffeine is restored. About a year after quitting caffeine, safe doses will begin to work again, and the person who once suffered from the disorder will again be able to occasionally drink coffee or tea.

How to calculate your optimal caffeine intake

If coffee is your favorite of all caffeinated beverages, hitting the recommended 400 mg of caffeine is pretty easy. It is enough to drink no more than two cups of brewed or no more than four cups of instant coffee – provided that the volume of the cup does not exceed 230 ml.

But if you drink other caffeinated beverages, such as tea or energy drinks, or take medications with caffeine, you need to consider the concentration of caffeine in all these products. Usually this information is on the label.

And you can also focus on the plate, which was calculated by the authors of the international guide for doctors Uptodate.

5 signs that you drink too much coffee

Medicine in a spoon, poison in a cup.

Today, the wisdom of the ancient doctors applies to your favorite drink.

In defense of coffee

Modern research suggests that almost everyone can drink good grain (not instant) coffee, including hypertensive patients and core patients. It has been proven that coffee is useful in liver diseases, prevents the transition of hepatitis to cirrhosis, and cirrhosis to cancer. In patients with hypertension, if they do not drink coffee for the first time, the drink does not cause a further increase in pressure. There are scientific papers that say that regular coffee consumption reduces the risk of heart attacks, recurrent heart attacks and arrhythmias.

But if we are talking about “medicine in a spoon” (or in our case – 1-2 cups of coffee a day), if you can’t live even a couple of hours without a coffee break, there are…
