Effects Of Caffeine On The Brain

Migraine Headaches and Caffeine Migraine Headache Relief Dr.Berg

When you drink coffee, caffeine can be absorbed quickly by the gut before it reaches the brain. Once there, the substance brings a stimulating effect on brain cells.

This is because the chemical structure of caffeine is similar to that of adenosine, which has relaxing effects on the central nervous system. Therefore, caffeine can fit into the brains adenosine receptors, thus preventing them from making you feel tired.

In turn, the blocked adenosine receptors trigger the production of dopamine and other natural stimulants. This further reduces tiredness and increase alertness. The end effects of caffeine on the brain is improved motivation, self-confidence, concentration, and a feeling of alertness.

Are Caffeine Pills Worse For You Than Coffee

It is clear that neither is entirely better than the other, since they both offer benefits to the individual. The downside is that caffeine pills can become addictive, since they are twice as strong as regular coffee and require less effort to consume. If you take too many caffeine pills, you may become addicted.

Study: Excess Caffeine Intake Is A Migraine Trigger

In a study in The American Journal of Medicine, 98 participants with episodic migraine completed an electronic diary each morning and evening for six weeks.

Within the diary, the participants reported their caffeinated beverage intake, as well as their migraine characteristics and other lifestyle factors .

Can Caffeine Ease Migraine Attacks

A variety of drugs used to treat headaches, such as Excedrin, Anacin, and Midol, contain caffeine.

This is because caffeine may reduce the sensation of pain through its effects on adenosine receptors, which influence pain signaling in the brain.

While research around caffeine and migraine is still ongoing, its thought that since adenosine is involved in the physiological processes associated with migraine attacks, caffeine may be able to reduce some of the pain associated with them via its effect on adenosine receptors.

However, the amount of caffeine consumed and the frequency of consumption, have a lot to do with its beneficial effects.

Caffeine Withdrawal and Headaches  7 Tips for Relief and ...

There is evidence that caffeine may reduce pain sensation through its effects on adenosine receptors . The antinociceptive effects of caffeine may be explained by an inhibition of cyclooxygenase activity as well as adenosine receptor antagonism. Caffeine acts not only by central blocking of adenosine receptors, which affects pain signaling, but also by blocking peripheral adenosine receptors on sensory afferents . It was demonstrated that a 200 mg caffeine dose can inhibit the analgesic effects of transcutaneous electrical nerve stimulation . Caffeine combined with a standard dose of analgesics led to an increased proportion of individuals with a satisfactory level of pain relief . Laska et al. found that, in combination with paracetamol or aspirin, caffeine reduced the amount of analgesic needed to reach the same effect by approximately 40% . Other clinical effects in these patients may be linked with the promotion of the absorption of analgesics by rapid lowering of gastric pH. Nevertheless, meta-analyses of caffeine combined with ibuprofen, paracetamol, or acetylic acid found only weak adjuvant effects in patients with postoperative pain .

Caffeine Caffeine Withdrawal And Chocolate

People are often unaware of the amount of caffeine hidden in the everyday foods they consume. A two-ounce square of dark chocolate contains about forty grams of caffeine, the equivalent of a shot of espresso. Lets not forget chocolate in beverages, ice cream, frozen yogurt, toppings, cookies, cakes, and brownies.

Table 1 provides generic measures of the caffeine contained in some foods, drinks, and medicines. Note that caffeine content will vary with brands and brew times. A simple internet search will yield more specific content information for most brands on the market.

Have you ever heard the advice that drinking a cup of strong coffee can ward off a migraine? According to one theory of migraine pain, the reason this works is that blood vessels in your head and face dilate as a result of neurochemical reactions in your brainstem. The inflamed vessels then disturb the nerves around them. Caffeine constricts those blood vessels and reverses the inflammation.

The problem is that regular consumption of one or more cups per day can cause a rebound effect when that intake is skipped or delayed and the constricting caffeine wears off, which can happen within twenty-four hours.

Drinking This Much Coffee May Trigger Migraines

Three or more caffeinated drinks a day is linked with migraines.

Drinking too much coffee or other caffeinated drinks may be a trigger for migraines among people prone to these severe headaches, a new study suggests.

The study researchers found that, among people with periodic migraine headaches, consuming at least three caffeinated drinks a day was tied to a higher likelihood of experiencing a migraine on that day or the following day. However, consuming only one or two caffeinated drinks a day was generally not associated with migraines, the study found.

Although many people anecdotally report that caffeine tends to trigger their migraines, few rigorous studies have examined this link. Indeed, the new study, published today in The American Journal of Medicine, is one of the first to examine whether daily changes in caffeine intake are tied to the onset of migraines.

“Interestingly, despite some patients with episodic migraine thinking they need to avoid caffeine, we found that drinking one to two servings day was not associated with higher risk of headache,” study senior author Dr. Suzanne Bertisch, an assistant professor at Harvard Medical School and a clinical investigator in the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital in Boston, said in a statement. Still, more research is needed to confirm the findings “but it is an important first step,” Bertisch said.

Food And Drinks Containing Caffeine

Caffeine may either hurt or help with headaches. If you already have a headache, drinking a bit of caffeine may help to alleviate your symptoms. During many headaches, the blood vessels around your head swell. Caffeine constricts these blood vessels, reducing your pain.

However, if you drink caffeine regularly and then stop, it may take your body several days or even weeks to readjust. One of the main symptoms of caffeine withdrawal is a headache. The blood vessels in and around your head swell when they are no longer regularly constricted by caffeine.

What Are The Side Effects Of Too Much Caffeine

Why Purity Coffee Does Not Cause Caffeine Headaches or Heartburn

The side effects of too much caffeine can vary from person to person and from one day to the next. The amount of caffeine in your blood is related to the amount of caffeine you take in over time. The effects of caffeine are not just related to the caffeine itself other factors such as how you take it and your own physiology come into play. Other factors to consider in understanding how caffeine affects you include the following: What is the caffeine source? Have you developed a tolerance to caffeine or do you still experience withdrawal symptoms when you stop? How do you take your caffeine? What is your weight, age, and overall health? What is your state of mind when you take your caffeine? How much caffeine do you drink? You can get too much caffeine by drinking too much coffee, tea, or soda or by eating too much chocolate. The following table lists possible side effects of too much caffeine..

Caffeine As A Risk Factor For Chronic Migraine

Theres evidence that too much caffeine consumption is a risk factor for developing chronic migraine, says Spears.

Chronic migraine is when a person experiences 15 or more days per month of headache with migrainous features, according to the Migraine Research Foundation.

Its estimated that chronic migraine affects about 1 to 2 percent of the general population and close to 8 percent of people with migraine. Each year approximately 3 percent of people with episodic migraine convert to having chronic migraine each year, according to a paper published in 2016 in the Nature Reviews Neurology.

A New Study About Coffee And Migraines: How Much Is Too Much

In a new study published in the American Journal of Medicine, researchers asked 98 people with migraines to keep a diet diary that included how often they consumed caffeinated beverages . This information was compared with how often they had migraines. Heres what they found:

  • The odds of having a migraine increased for those drinking three or more caffeinated beverages per day, but not for those consuming one to two servings per day the effect lasted through the day after caffeine consumption.
  • It seemed to take less caffeine to trigger a headache in those who didnt usually have much of it. Just one or two servings increased the risk of migraine in those who usually had less than one serving per day.
  • The link between caffeine consumption and migraine held up even after accounting for other relevant factors such as alcohol consumption, sleep, and physical activity.

Interestingly, the link was observed regardless of whether the study subject believed that caffeine triggered their headaches.

Does Caffeine Treat Or Trigger Headaches

What Does a Caffeine Headache Feel Like?

Many people ask whether caffeine can treat or trigger a headache. The answer is that caffeine can do both.

Caffeine can provide relief for a headache.

During a headache, blood vessels swell, tighten or go through other changes, causing an increase in blood flow around the brain. This increase blood flow pressures surrounding nerves, which send pain messages to the brain. This brings on the headache.

Caffeine has vasoconstrictive properties, meaning that blood vessels narrow to restrict blood flow, thereby alleviating the pain. Also, when caffeine is taken in combination with pain medicines, such as aspirin, ibuprofen or acetaminophen, it increases the absorption and strength of the medication to provide faster relief.

Caffeine can trigger a headache.

When caffeine is consumed regularly, the body becomes dependent on its effects. And because caffeine narrows the blood vessels that surround the brain, when consumption is stopped, the blood vessels enlarge. This causes an increase in blood flow around the brain and pressures surrounding nerves. This can then trigger what is known as a caffeine withdrawal headache. Withdrawal headaches can last for a couple of weeks because it takes the body a while to adjust to not having caffeine in its system.

What Is A Vascular Headache

A Vascular headache is a type of headache that is usually attributed to the narrowing of the arteries that provide blood to the head, resulting in restricted blood flow. These headaches often appear suddenly, and can be accompanied by nausea, vomiting, and sensitivity to light and sound. Vascular headaches are usually short-lived and relatively easy to treat, though they can be dangerous if left untreated..

How Can I Treat A Caffeine Withdrawal Headache

  • Gradually reduce your consumption of caffeine instead of stopping suddenly. This can help to reduce the severity of your withdrawal symptoms, although it may take longer for them to go away completely completely. Reduce how much caffeine you have each day over two to three weeks or longer if needed. Put a plan in place to help you stay on track.
  • Headaches can be treated with over the counter medications, such as acetaminophen , ibuprofen and aspirin. Remember to avoid medications that contain caffeine.
  • Rest and get plenty of sleep.
  • Drinking plenty of water to stay hydrated.

    Migraine Vs Caffeine Withdrawal

    Another way that caffeine may indirectly lead to an intense headacheor what feels like a migraineis through withdrawal. For example, if youve been drinking two cups of coffee per day for the last number of months or years and stop cold turkey, youll likely feel it one way or another. One effect could be severe headaches, as your body gets used to going without something its grown accustomed to having.

    When caffeine is consumed, it activates adenosine receptors, which is what staves off drowsiness and keeps you alert. As you consume caffeine more frequently, you may require more of it to get the same effect as tolerance builds. Cutting off that supplywhich may have turned into a dependencecan lead to withdrawal.

    If youve recently stopped drinking coffee cold turkey and have been experiencing extremely painful headaches there are a couple of options. The first is to stick it outyou should be over it within a few days. The second is to slowly wean yourself off coffee by lowering consumption daily.

    Does Caffeine Help Relieve Headaches It Can But Not If You Drink Too Much

    • Drinking pain or trigger it, depending on the amount you consume.
    • Caffeine narrows blood vessels, which may relieve pain caused by some headaches, like migraines.
    • However, if you become dependent on caffeine and stop drinking it, you may experience headaches as a result of caffeine withdrawal.
    • This article was reviewed by Jason R. McKnight, MD, MS, a family medicine physician and clinical assistant professor at Texas A& M College of Medicine.

    Caffeine and headaches have a complicated relationship. In fact, caffeine can either relieve or trigger headaches, depending on how much of it you consume, and how frequently.

    Caffeine which is a central nervous system stimulant turns up in soft drinks, sports drinks, coffee, tea, chocolate, and more, so it’s easy to see why 80% to 90% of all adults in North America consume it regularly.

    Here’s everything you need to know about how caffeine can impact headaches and how much of it you should consume for positive effects.

    Migraine Headaches: Still Mysterious After All These Years

    Migraine headaches are quite common: more than a billion people reportedly suffer from migraines worldwide. Yet, the cause has long been a mystery and it still is.

    Until recently, the going theory was that blood vessels around the brain go into spasm, temporarily constricting and limiting blood flow. Then, when the blood vessels open up, the rush of incoming blood flow leads to the actual headache.

    That theory has fallen out of favor. Now, the thinking is that migraines are due to waves of electrical activity spreading across the outer portions of the brain, leading to inflammation and overreactive nerve cells that send inappropriate pain signals. Why this begins in the first place is unknown.

    Migraines tend to run in families, so genetic factors are likely important. In addition, chemical messengers within the brain, such as serotonin, may also play a central role in the development of migraines, though the mechanisms remain uncertain.

    People prone to migraines may experience more headaches after coffee consumption , but coffee itself, or the caffeine it contains, is not considered the actual cause of migraines. Certain foods or drinks like coffee are thought to trigger episodes of migraine, but the true cause is not known.

    How Do I Stop Being Sensitive To Caffeine

    To treat caffeine sensitivity, a person should be aware of how caffeine affects their health. For example, people who experience insomnia or anxiety may require sleeping aids or antidepressants. Instead of taking medication to treat the side effects of caffeine, they can reduce their consumption of it.

    But When Does Caffeine Help A Migraine

    Caffeine is what Dr. Crystal calls a âdouble-edged sword,â because while it can trigger headaches, itâs also an active ingredient in some migraine relief medications.

    According to the American Migraine Foundation, caffeine affects the activity of adenosine, a naturally occuring and necessary brain substance. During migraine attacks, adenosine levels in the blood rise. Caffeine can block specific brain cell receptors adenosine typically bind to, stopping its effects. Caffeine also has vasoconstrictive properties that can restrict blood flow. Since blood vessels vasodilate, or get larger, before a migraine attack, caffeine can help counterbalance that effect, thus decreasing pain.

    âCaffeine helps relieve headaches by its own analgesic, or alleviating, effects, and by enhancing the analgesic effects of aspirin, acetaminophen and ibuprofen,â Dr. Crystal says.

    Thereâs still much research to be done to determine exactly how caffeine results in acute anti-migraine and pain control, but the evidence is there: A 2017 study published by The Journal of Headache and Pain found that combining caffeine over-the-counter pain relief medications significantly improved relief compared to using the medication alone. And while treating headaches with non-medical options is sometimes effective, The American Migraine Foundation recommends limiting this to two days a week.
