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:

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.

How Are Anxiety Disorders Treated?

There are a number of treatment approaches for anxiety disorders. The type of treatment you receive will depend on your anxiety symptoms and type of disorder.

Not every treatment works for every person. You may need to try a number of treatments, or combinations of treatments, before finding what works for you.

The main treatments for anxiety disorders include:

• Psychotherapy (talk therapy with a trained mental health professional)
• Medications
• Exercise
• Complementary and alternative treatments

What Medications Are Prescribed for Anxiety Disorders? 

A range of medications are available to treat anxiety disorders, and they’re often used in conjunction with therapy. You may also be prescribed a combination of medications.

The two general types of medications used to treat anxiety disorders are:

• Antidepressants (despite the name, they’re the first-line medication for anxiety)
• Anti-anxiety medications (sometimes called anxiolytics)

Although in the short-term, drugs may seem cheaper and less time-consuming than therapy, you may not be able to overcome your anxiety using medication alone.

What Kind of Therapy Is Best for Anxiety?

A form of psychotherapy called cognitive behavioral therapy (CBT) is often used to treat anxiety disorders. CBT focuses on changing unhealthy thinking and behavior patterns through talk sessions with a trained therapist. Many studies have shown that it is very effective in the treatment of anxiety.

During CBT, you’ll work together with your therapist to develop positive techniques for coping with your anxiety symptoms. You’ll also learn to identify and manage factors that contribute to your anxiety.

CBT may involve learning how to change harmful thought patterns so that you experience less anxiety over time. You also may learn relaxation techniques — such as deep-breathing exercises — to help counteract your symptoms.

CBT is not a quick fix. A typical course of CBT takes about three or four months, but you may start to see benefits sooner than that, and the benefits may last much longer.

“One of the biggest strengths of CBT is that the improvement tends to be durable and long-lasting,” says Suma Chand, PhD, the director of the cognitive behavior therapy program at St. Louis University School of Medicine in Missouri. “By the end of the sessions, the person has learned strategies that can be used for the rest of his or her life. Most importantly, the treatment results in changes in the thinking patterns and beliefs that had maintained their anxiety.”

There are several different variations of CBT. One type of CBT is called exposure therapy. Exposure therapy is used to treat certain phobias and obsessive-compulsive disorder, among other conditions. It involves gradually facing a feared situation or object, causing you to become less fearful over time.

Research on the efficacy of therapy administered through the internet is still developing, but some studies suggest it might be just as helpful as going into your therapist’s office, depending on the condition being treated.

Other forms of therapy, such as dynamic therapy (what you probably think of when you think of traditional talk therapy) can also be helpful, depending on the form of anxiety and the amount of time one is able to spend in therapy.

Does Exercise Reduce Anxiety?

Exercise may be used alongside medication and/or psychotherapy to treat anxiety disorders.

One review of multiple studies, published in 2015, found that exercise may be as helpful as medication or CBT to those with anxiety or anxiety disorders and may work better than a placebo (inactive pill).

The findings in another review of studies, published in 2017, underscore that exercise significantly reduced symptoms and is an important treatment option for people with anxiety disorders.

But experts recognize that exercise may be the last thing those struggling with anxiety want to put on their to-do list, and it can be hard to put those routines in place. “Some people have anxiety so extreme that a 10-minute walk can be hard to undertake,” says Beth Salcedo, MD, a past board president of the Anxiety and Depression Association of American (ADAA).

“Anxiety and depression, which often occur together, lead to lower motivation, so it may be that medication might help in this case to give patients enough energy to exercise,” says Ken Duckworth, MD, the chief medical officer for the National Alliance on Mental Illness.

Natural Remedies for Anxiety — Do They Work?

• Meditation There’s some scientific evidence that meditation — especially a type of meditation training called mindfulness-based stress reduction — can help reduce anxiety and depression symptoms.
• Yoga Yoga combines physical postures, breathing exercises, and meditation. Research suggests that practicing yoga can help reduce anxiety by reducing the body’s stress response.
• Acupuncture Some scientific evidence suggests that acupuncture — the Chinese practice of inserting thin needles into the body at certain points — can help reduce anxiety symptoms. But the research is variable and inconsistent.
• Kava This dietary supplement comes from the crushed root of a Polynesian shrub. A review of studies published in 2018 found that kava appeared to be an effective short-term (less than eight weeks) treatment for anxiety.Speak with your doctor before using kava; kava supplements have been linked to severe liver damage in some people. 
• Lavender Lavender oil is commonly used in aromatherapy. Some people believe that this scent has a calming or soothing effect. A 2019 meta-analysis of evidence on the use of lavender to lower anxiety levels found that it may be effective but that more, high-quality studies are needed.
• St. John’s Wort Supplements made from the St. John’s wort plant have been used to treat depression, anxiety, and sleep disorders. But research hasn’t shown that it’s effective in treating anxiety, and it may be dangerous to take with certain drugs, including antidepressants, contraceptives, and HIV and cancer medications.
• Valerian This medicinal herb has been used to treat anxiety and depression for centuries.While research suggests it can help with insomnia, there isn’t enough scientific evidence to know whether valerian is an effective treatment for anxiety disorders.

Fatalities about the dangers of coffee, which you did not know

Experts from the Institute for Cognitive Modeling talk about how caffeine consumption affects anxiety and why espresso is not the best drink during the war.

Research shows that cutting down on caffeine benefits people with anxiety disorders, but even one cup a day is a serious trigger for anxiety.

Think of caffeine as an “anxiety booster”. For example, if your anxiety is at level 5, then a few hours after drinking caffeine, it is likely to be at level 8, which rises to 10 or more in the evening.

Also, if you don’t sleep well at night, your anxiety will be even higher in the morning. But then you will most likely get your morning caffeine fix, which will start the same process again.

Scientists conducted a study looking at the effects of caffeine in patients with generalized anxiety disorder (GAD) compared to healthy subjects and found that patients with GAD were abnormally sensitive to caffeine.

This connection between caffeine and anxiety is not obvious, because immediately after drinking coffee we feel great, and anxiety symptoms begin to appear only after a few hours.

Caffeine is characterized by increased mobility. The caffeine molecule is so small that it reaches the brain in just 20 minutes, easily passing the blood-brain barrier. Once the molecule is found in the brain, it blocks the uptake of adenosine, a neurotransmitter that signals the brain to be drowsy. Plus, caffeine stimulates the central nervous system and slightly increases blood pressure.

The fact that caffeine is associated with panic attacks has been proven by experiment. It turned out that 52% of people experienced panic attacks or anxiety after drinking coffee and caffeine. At the same time, a similar reaction was observed in 41% of first-line relatives, although people had never had panic attacks before. In some cases, caffeine also caused hallucinations (this is how the combination of caffeine and high stress levels worked).

Caffeine is not only found in coffee. It’s also found in black and green teas, sodas, and energy drinks, so to eliminate caffeine, you’ll need to eliminate those drinks from your diet as well.

By the way, giving up caffeine results in a complete withdrawal syndrome. It manifests itself in headaches, muscle pain, fatigue, apathy and depression.

Therefore, if you suffer from anxiety disorders and are addicted to coffee, it should be reduced gradually.

If you’re not ready to give up caffeine for good, at least try eliminating it from your diet for 60 days and track your anxiety levels during that period to note any changes.

1. Drink plenty of water throughout the day to stay hydrated and facilitate caffeine clearance.

2. Start drinking herbal teas. The best teas for anxiety are chamomile, valerian root, and oat straw.

3. If you experience caffeine withdrawal symptoms such as headaches, take a caffeine-free pain reliever if needed.

4. Breaking the habit of drinking coffee can be very difficult. If you still want to drink coffee from time to time, you should first avoid it for at least six weeks to completely detoxify your body.

How does caffeine affect the brain? Find out how caffeine affects thinking, attention, memory and emotions. Determine the dosage and frequency of caffeine intake to get the most benefit and avoid negative health effects.

Loving coffee makes it easy to spend hours at work or enjoy loud conversations with friends. Caffeine, a drink loved by millions of people around the world, is one of the most popular psychoactive substances that change the way the human brain works.

For centuries, coffee has been consumed as a tonic, concentration enhancer and mood enhancer. That is why he often becomes a companion of those who want to increase the efficiency of work or study.

In this article, we’ll take a look at the effects of caffeine on the brain – exactly what processes change after drinking it, how much this effect really helps us in everyday life, and what are the risks and limitations of drinking coffee.

Interesting fact: Former French President François Mitterrin drank up to 50 cups of coffee a day!

What is caffeine?

Caffeine is a naturally occurring alkaloid found in a number of plants, including coffee beans, tea leaves and cocoa. It is known for its stimulating effect and ability to improve concentration, mood and physical endurance.

Caffeine affects the brain due to its chemical structure, which is similar to the two main brain neurotransmitters, adenosine and dopamine. Adenosine plays an important role in the regulation of sleep and wakefulness, causing fatigue and drowsiness. When caffeine binds to adenosine receptors, it blocks their action, resulting in a feeling of wakefulness and increased energy. Dopamine is a neurotransmitter that is responsible for pleasure, motivation, and pleasure. Caffeine also affects the release of dopamine in the brain, which can cause euphoria and improve mood.

In addition, caffeine can increase the speed and accuracy of reaction, improve memory and cognitive functions in general. Its effect depends on many factors, including dose, food, drink, and other ingredients such as sugar and milk, which can affect the rate of absorption. However, be aware that too much caffeine can cause negative side effects such as insomnia, anxiety, and increased heart rate.

How does caffeine work in the brain?

Caffeine, a chemical known to everyone as a central nervous system stimulant, affects the brain in a variety of ways. It blocks the action of the neurotransmitter adenosine, which controls brain activity and causes fatigue.

Caffeine also increases serotonin, a neurotransmitter responsible for improving mood and reducing stress levels in the brain.

In addition, caffeine helps improve memory and concentration, increase alertness and speed up the brain’s response to various stimuli.

• Blocks adenosine – increases dopamine, norepinephrine and serotonin levels in the brain
• Increases productivity – improves mood and helps manage stress
• Improves memory and concentration 901 87 – increases attentiveness and speeds up the reaction of the brain

Although caffeine is good for our brain, caffeine in large doses can lead to insomnia, high blood pressure, heart problems and other negative effects. Therefore, it is important to control your caffeine intake and not exceed the recommended dose of 400 mg per day.

Effect of caffeine on the brain: Activation of the nervous system

Caffeine is a stimulant of the central nervous system, its use promotes activation of brain activity, increases alertness and attention.

When used in moderation, caffeine can be helpful in improving mental performance and productivity. However, excessive caffeine consumption can cause jitteriness, insomnia, high heart pressure, and other unwanted effects.

1. Influence on memory and cognitive functions. Studies have shown that moderate caffeine intake can improve memory, reaction time, and other cognitive functions. However, when consumed in excess, negative effects such as anxiety and insomnia are possible, which can impair cognitive function.
2. Influence on mood. Caffeine may improve mood and boost self-esteem by increasing dopamine levels. However, caffeine consumption can backfire and cause anxiety and depression.

Remember that adults should not exceed 400 mg of caffeine per day (that’s about 4 cups of coffee). People who suffer from insomnia, cardiovascular disease, or gestational hypertension are advised to limit their caffeine intake.

Increasing the concentration of hormones

Caffeine affects the production of hormones in the body, including adrenaline and cortisol. Adrenaline increases the activity of the nervous system and causes an increase in heart rate and blood pressure. Cortisol, in turn, increases blood sugar levels and increases the breakdown of fat cells.

When caffeine is consumed, its molecules begin to fight for access to receptors that are responsible for the transmission of impulses in the brain. As a result of this struggle, the number of neurotransmitters in the synapses increases, which leads to an increase in the level of dopamine, norepinephrine and serotonin, which are responsible for the emotional state and mood.

• Dopamine – stimulates feelings of pleasure and loyalty to rewards.
• Norepinephrine – increases attention, interest, response to stress and perception of pain.
• Serotonin – regulates mood, sleep, appetite, immune system function, memory and sexual behavior.

In summary, caffeine intake may have a positive effect on memory, attention, mood, concentration, and response to stress. However, too much caffeine can cause side effects such as insomnia, anxiety, hand tremors, dizziness, and especially sensitive people may experience headaches and severe confusion.

The duration of the effect of caffeine on the brain

Caffeine is one of the most common stimulants for brain activity. It is reported that its effect occurs within 15-20 minutes after ingestion and lasts from 4 to 6 hours.

Caffeine Metabolism

Caffeine metabolism occurs in the liver and takes approximately 5-6 hours to halve the caffeine content in the blood. Excessive consumption of caffeine can slow down this process, increasing the time that caffeine takes to act on the body.

Caffeine dosage

Caffeine dosage can also affect the duration of its action. A smaller dose of caffeine, such as found in a cup of coffee, may have a shorter effect than a larger dose of caffeine, such as found in energy drinks.

In general, the duration of the effect of caffeine on the brain can be different for each person, and is determined individually. It is important to remember that consuming large amounts of caffeine can cause negative effects such as insomnia, headaches, and anxiety.

How does caffeine affect memory and concentration?

Caffeine is a nervous system stimulant that may affect various brain functions, including memory and concentration. When we drink coffee, caffeine increases the activity of neurons in our brain, which can lead to improved concentration and alertness.

Studies show that caffeine can improve short-term memory. This is because caffeine is able to increase the level of neurotransmission in the hippocampus, the part of the brain responsible for processing information and forming new memories.

In short, caffeine can affect memory and concentration, but it must be dosed correctly to achieve maximum effect.

Possible side effects of caffeine

Drowsiness

Paradoxically, caffeine can cause drowsiness. This is due to its effect on the central nervous system – it blocks adenosine receptors, which signal the brain to rest. When the effect of caffeine ends, adenosine actively begins to interact with its receptors, which causes drowsiness.

Nervousness

Caffeine is a CNS stimulant and in high doses can cause nervousness, anxiety and irritability. This is due to the fact that caffeine increases the release of adrenaline and norepinephrine, hormones responsible for the “combat” and “alarm” reactions of the body.

Increased blood pressure

Caffeine increases the contractility of the heart and constricts blood vessels, which leads to an increase in blood pressure. If you already have high blood pressure problems, caffeine consumption can make things worse.

Sleep problems

The effects of caffeine on the brain can last up to several hours after consumption. This means that if you drink coffee in the late afternoon, you may experience sleep problems due to a delay in sleep onset.

Dehydration

Caffeine is a diuretic, meaning it increases fluid excretion in the urine. Therefore, the use of large amounts of caffeine can lead to dehydration of the body, especially in hot weather.

Who should not consume caffeine?

Pregnant and breastfeeding women it is best to limit or avoid caffeine intake, as caffeine can cross the placenta to the fetus and be excreted in breast milk, negatively affecting the development of the baby’s nervous system.
People with high blood pressure should also limit their intake of caffeine as it can increase blood pressure by stimulating effects on the central nervous system.
People with insomnia and nervous disorders should also be careful with caffeine intake, as it can cause restlessness, anxiety, insomnia, and exacerbate the symptoms of some mental disorders.
People who are hypersensitive to caffeine should also not use it as it may cause headache, irritability, tachycardia and hand tremors.

Myths and reality about the use of caffeine

Myth:

Caffeine negatively affects the cardiovascular system.

Reality: Caffeine consumed in moderate doses does not harm the heart and blood vessels. Conversely, moderate caffeine intake may reduce the risk of heart disease and stroke.

Myth:

Caffeine is addictive.

Reality: Although caffeine can cause mild physical dependence, this dependence is not comparable to addiction to drugs. Most people who use caffeine can control their intake and stop without problems.

Myth:

Caffeine increases the risk of cancer.

Reality: Several studies have been done on this topic, but at the moment there is no evidence that caffeine can increase the risk of cancer. Some even claim that moderate caffeine consumption can reduce the risk of certain types of cancer, such as liver cancer and breast cancer.

Myth:

Caffeine negatively affects the digestive system.

Reality: For most people, moderate caffeine intake does not cause digestive problems. However, for some people with a sensitive stomach or intestines, caffeine can cause discomfort, nausea, and diarrhea.

So, the use of caffeine is not as dangerous as it is commonly thought. In fact, moderate caffeine consumption may even have positive health effects. However, as with any other product, caffeine intake should be deliberate and in moderation.

How to drink coffee correctly?

Choose the right serving

Caffeine addiction can be harmful to your health, so don’t exceed your daily allowance: 400 mg of caffeine, which is equivalent to 4 cups (250 ml) of regular coffee.

Strictly observe the order, do not drink coffee after 16:00, as caffeine leaves a life-giving effect and prevents you from falling asleep at night.

The right additions

The chemical combination found in pure coffee is hard on the body, so add sugar, cream or milk to your coffee.

Limit your diet and minimize the pastries and sugary drinks that make us sleepy and addicted to coffee. If you can’t live without your daily dose of caffeine, experiment with coffee-free drinks.

Do not drink coffee on an empty stomach

Drink coffee after meals, not on an empty stomach. If you drink coffee on an empty stomach, the caffeine will fuel oxygen in the stomach, and this can cause heartburn, sickness, and even ulcers. Also, before you just drink coffee at an interview, think about the following things.

• Coffee contains caffeine, which is a stimulant and can wake you up before an interview.
• Coffee can make your heart beat faster, which can be uncomfortable.
• Coffee can also stimulate stomach acid, which can induce health during an interview.

In general, the correct use of caffeine is not only to enjoy the amazing taste, but also to learn how to use caffeine wisely and for the health benefits of the body and will greatly help the brain in an interview. Moreover, coffee drinks can now be extraordinarily stylish and beautifully decorated, pay attention to this.
