Dangerous Heartbeat and How to Calm It

A Detailed Guide to Understanding Heart Rate

Heart rate is a key indicator of our heart's health and the overall state of the body. Its speed and regularity can signal anything from everyday stress to serious illnesses. The question of how high a heart rate can be dangerous is not just a matter of curiosity – understanding it can save a life.

What is Heart Rate and How Does It Work?

Heart rate is the result of electrical impulses that stimulate muscle contractions of the heart. This movement pumps blood rich in oxygen and nutrients throughout the body. Heart rate, or the number of beats per minute (BPM), naturally varies depending on activity, emotions, health status, and other factors. While at rest, a normal heart rate is lower, physical activity or stress can increase it.

Everyone's heart functions individually. Some people naturally have a faster or slower heart rate, which doesn't necessarily indicate a problem. However, there are certain limits that the heart rate should not exceed for long periods.

What is a Normal Heart Rate?

A typical resting heart rate for adults is considered to be between 60 and 100 BPM. Athletes or very physically active individuals often have a heart rate below this value, sometimes around 40 BPM, due to a stronger heart muscle that can pump blood more efficiently.

Children naturally have a higher heart rate – for example, newborns can have up to 120 BPM, while adolescents approach adult norms.

However, if your resting heart rate consistently exceeds 100 BPM, it could be tachycardia, a condition where the heart beats too fast. Conversely, values below 60 BPM (outside of athletes) can indicate bradycardia, or slow heart activity.

How High a Heart Rate is Dangerous?

Assessing a dangerous heart rate requires not only looking at numerical values but also considering context and accompanying symptoms. In a healthy person, the heart rate can increase to 150–180 BPM during exercise, which is considered natural.

However, in a resting state, any heart rate above 120 BPM is considered alarming, especially if it persists long-term or is accompanied by these symptoms:

• Shortness of breath and difficulty breathing.
• Chest pain or a feeling of pressure.
• Dizziness, fainting, or nausea.
• Palpitations, which is a noticeable pounding of the heart that cannot be ignored.

Tachycardia can lead to serious problems such as atrial fibrillation, heart failure, or even sudden cardiac arrest. Therefore, it is crucial to pay attention to how high a heart rate is dangerous and respond promptly.

Why Might Heart Rate Be Elevated?

An elevated heart rate has various causes. Some are natural and temporary, while others require medical attention. The most common causes include:

• Stress and anxiety: Emotional stress activates the sympathetic nervous system, increasing heart rate.
• Dehydration: Lack of fluids makes it harder for the heart to pump blood, which can increase heart rate.
• Infection or fever: A rapid heart rate is often a natural response to infections.
• Excessive caffeine or alcohol consumption: These substances affect heart activity.
• Hormonal imbalance: For example, increased activity of the thyroid gland can cause tachycardia.
• Heart disease: Atherosclerosis, ischemic heart disease, or arrhythmias can cause increased heart rate.

How to Calm the Heart Rate?

If you feel your heart rate is too high, try some of the following methods to calm it down. These practices not only reduce heart rate but also support overall heart health.

Breathing Techniques

Deep and slow breathing can quickly activate the parasympathetic nervous system, calming the body. Try the "4-7-8" technique, where you inhale for four seconds, hold your breath for seven seconds, and exhale slowly for eight seconds.

Hydration

Dehydration is a common cause of increased heart rate. If you're dehydrated, your blood thickens, placing a greater demand on the heart. Regularly drink plain water and avoid sugary drinks.

Natural Herbs

Herbs like lemon balm, valerian root, or St. John's wort have calming effects on the nervous system and heart. Lemon balm tea or valerian tincture can help stabilize heart rate.

Relaxation and Meditation

Meditation, yoga, or simple relaxation can reduce levels of stress hormones like cortisol, thereby lowering heart rate. Try to spend at least ten minutes a day calming your mind.

Physical Activity

Regular exercise strengthens the heart and helps to reduce resting heart rate over the long term. An ideal combination is aerobic activities like walking or swimming with strength training.

When is it Time to See a Doctor?

If none of these methods provide relief, or if increased heart rate occurs frequently, it is important to consult a doctor. A heart rate that is consistently outside the norm may signal a more serious health condition that requires professional examination, such as an ECG or blood tests.

The heart is one of the most important organs in our body, and its health cannot be underestimated. Understanding whether a high heart rate is dangerous and being able to respond to warning signals are key to preventing serious problems. Take care of your heart – and it will reward you with a long and healthy life.
