In this text we will discuss the relationship between drinking coffee and chest pain. In addition we will discuss the harm and benefits of drinking coffee.

Why does my chest hurt after drinking coffee?

Chest pains after drinking coffee could be the effects of too much caffeine on your body. 

The stimulant effects of caffeine, when consumed in moderation, can have other desirable effects, such as improving mental alertness and concentration. On the other hand, too much caffeine can cause unwanted side effects.

While chest pain is an unlikely symptom, excessive consumption of coffee or caffeine can make you feel restless, anxious, nervous, or have headaches.

Caffeine can act as a vasoconstrictor, a substance that narrows blood vessels, so it has been suspected to contribute to chest pain, blood pressure, or heart disease.

But the cardiovascular impact of caffeine is not so simple. Even after consuming caffeine, a slight and temporary constriction of blood flow can occur, which can lead to a short-lived increase in blood pressure or heart rate.

However, this effect is more pronounced in people who do not regularly consume caffeinated beverages.

Caffeine acts primarily as a vasodilator, which means it improves blood flow.

What is caffeine?

Caffeine is a chemical compound of the alkaloid family — a class of substances of basic character, derived mainly from plants — being present in about 60 types (as in the coffee bean).

In addition, it can also be found in industrialized products, such as some soft drinks, and is even present in the composition of some medicines (such as painkillers).

It is a psychoactive substance, that is, it acts directly on the central nervous system (CNS) and has the potential to alter brain functions and provide changes in perception, mood and even behavior.

In the case of caffeine, it is famous for its stimulating action, constantly used to increase physical potency and increase mental activity. Therefore, it is a great ally for when we need to stay more active and put aside sensations such as physical fatigue or drowsiness. Its peak of action occurs, on average, after 20 minutes of ingestion.

Is too much caffeine bad for you?

Yes, too much caffeine is bad for your health. Just like anything, too much caffeine can also be harmful. Even, in the most serious cases, this abusive consumption can even cause an overdose, and it is common for the person to present symptoms such as:

  • Accelerated heart rate
  • Delusions and/or hallucinations
  • Dizziness
  • Headaches
  • Fever
  • Difficulty breathing
  • Chest pains
  • Involuntary spasms.

How much caffeine should you consume in a day?

The American agency FDA considers as not harmful doses of less than 400 mg per day, divided into four or five cups of coffee or ten cans of soft drinks. 

So-called energy drinks have varying concentrations, reaching up to 200 mg of caffeine per can. Remember that the dose is cumulative, regardless of the type of drink. 

Drinking coffee with milk does not lessen its effects, it only changes the taste.

Caffeine is a stimulant substance and, in excess, it can cause insomnia, nervousness and anxiety, which can cause a general feeling of dissatisfaction. 

In addition, it stimulates the cardiocirculatory system promoting accelerated heart rate and headache. And it acts on the digestive tract causing stomach upset and nausea. 

There is no express contraindication for consumption by children or teenagers, but experts in the field consider its intake inappropriate, especially cola-type soft drinks.

Does drinking coffee have health benefits?

Yea! Moderate consumption of coffee can have benefits for your health. The greatest benefits of coffee come from the presence of caffeine.

Caffeine acts on the central nervous system as a direct stimulant by inhibiting the action of adenosine, this substance being a participant in the brain’s brake system, functioning as a discrete tranquilizer. 

By decreasing the effects of adenosine, caffeine leaves our brain on constant alert and with more attention and concentration, also decreasing mental fatigue.

Here is a list of some of the benefits of coffee for human health:

  • It boosts energy levels and makes you feel less tired
  • Helps to burn fat
  • Unlike sodas, coffee does not contribute to increased blood pressure
  • It raises adrenaline in the bloodstream, which means you’ll be better able to exercise
  • People who drink coffee frequently are less likely to develop type 2 diabetes, Alzheimer’s and Parkinson’s
  • It is a drink with very few calories
  • Coffee helps your brain to work more efficiently
  • Drinking coffee during the day decreases the risk of developing heart disease by 21%
  • The drink will make you happier and acts as a (weak) antidepressant
