Ever drank a few cups of coffee and felt like your heart was beating faster, or you experienced sudden chest pains? Well, there may be a reason for this, but it’s probably not what you’re thinking. What could coffee be doing to the heart if you’re experiencing chest discomfort? 

In all honesty, caffeine, the active ingredient in coffee, doesn’t typically cause any heart problems, nor chest pains for that matter. That is especially the case if you consume safe levels of caffeine every day (400mg).

How Caffeine Affects Your Heart and Body 

Coffee Caffeine

Many of us rely on coffee every morning to be our daily pick-me-up to get us going. Coffee stimulates our CNS (Central Nervous System), making us feel like we have the energy to tackle the world. 

What’s not so well-known is that coffee also encourages increased secretion of stomach acid, increases your blood pressure, and causes an increase in heart rate. People with caffeine sensitivity may experience adverse side effects of caffeine. 

If the heart beats fast enough and the blood pressure goes up high enough, it could discourage blood flow to the heart, causing chest pains. This isn’t the case for most people who drink coffee, and if you don’t have caffeine sensitivity but get chest pains after coffee, it’s more likely to be acid reflux. 

The American Heart Association says that coffee has plenty of antioxidants, which are great for your skin and body as well. Coffee also has the potential to reduce the risk for heart disease.

How Much Caffeine is Too Much? 

As mentioned, a healthy person can tolerate 400 milligrams of caffeine (more or less) daily, safely. That’s equal to about four cups of coffee and is considered moderate caffeine consumption, according to the Mayo Clinic. It is important to note that excess caffeine intake can still affect your body negatively in other ways. 

Here are some of the unpleasant symptoms that can be caused by drinking large amounts of caffeine regularly:

  • Tremors
  • Headaches
  • Heartburn
  • Insomnia
  • Irritability
  • Nervousness
  • Rapid heart rate
  • Frequent urination

The amount of coffee that produces these troublesome symptoms will vary from person to person, depending on their tolerance to caffeine. 

One individual could drink less than 400mg of coffee per day and experience these symptoms, while the next person who may or may not have a sensitivity can go over the 400 mg mark and be completely fine. 

It’s important to pay attention to your body and how it responds when you drink a certain amount of coffee or caffeinated beverages in general. Consult a physician should you experience difficulty breathing or persistent chest pains. 

Is Caffeine Dangerous for Some People? 

Aside from those with caffeine intolerance, other vulnerable groups of people also shouldn’t drink coffee for various reasons. 

The intake of caffeine increases your body’s production of the stress hormone cortisol. This hormone is responsible for triggering the fight or flight response when there’s a perceived threat or intense ordeal. 

This hormone gets secreted by the adrenal glands when stimulated by both the pituitary and hypothalamus glands. Cortisol suppresses other bodily functions to elicit a swift response to danger and stress.

When combined with specific medications, caffeine is more likely to cause elevated blood pressure or heart palpitations. You should avoid caffeine sources like coffee and energy drinks when using over-the-counter decongestants which contain ephedrine or drugs that contain theophylline and echinacea.

This combination of substances can also cause those unpleasant caffeine side effects.

Below is a list of people with conditions that may need to limit or avoid caffeine altogether:

  • People who have insomnia
  • Women who are pregnant or breastfeeding
  • Kids and teenagers
  • People who have ulcer disease or acid reflux symptoms
  • People who have anxiety

Conclusion 

In general, daily caffeine intake should never cause any form of chest pain. However, if you happen to have chest pain after having caffeine, it could be that you have a caffeine sensitivity. 

Remember that this is common with people not accustomed to having any form of caffeine. If you’re one of these people, you should avoid caffeine altogether.

Keep in mind that there is a list of people who should avoid caffeine because of preexisting conditions, such as pregnant and breastfeeding women, people with insomnia, and even children and teenagers. 

Finally, keep an eye out for certain over-the-counter medications that can make for a terrible experience when mixed with caffeine, such as ephedrine.

If you have any persisting pain, chest tightness, or discomfort, don’t hesitate to see a doctor immediately.

Happy (painless) Caffeinating!
