Tachycardia at Night: High Heart Rate Causes

So you too experienced the frightful feeling of tachycardia during the night? I know the feeling. Anyone who has ever lived through the phenomenon of not able to sleep because having tachycardia at night knows how disturbing it is. Your worry further increases the rate of your heartbeat.

Strong palpitations usually start suddenly, without any sign, and may occur on their own, but it is common to have other complaints. Such symptoms may include anxiety, fear, sweating, shortness of breath, and chest pain.

You’re dead right, it’s worrisome

No doubt about it tachycardia at night can have a dreadful impact on those who live it through since fast heartbeat and worry can form a vicious circle. The stronger you feel the heartbeat, the more you stress about, which further increases your heart rate. That is indeed a frightful phenomenon.

The circumstances must be investigated, as the tachycardia might be a cardiac arrhythmia. If your heart isn’t strong enough, a rapid heartbeat can lead to heart failure.

In some cases, another disease is present in the background, including infarction, cardiomyopathy, an endocrine disorder, thyroid disease, hormonal problems, diabetes, and kidney disease.

A laboratory test can determine what non-cardiologic diseases are in the background of strong palpitations. The good news is that it often turns out that it is not heart disease or any other illness but a more innocent phenomenon behind the high pulse.

Quite simply, it can also be caused by a chaotic emotional life, psychological problems, or a side effect of a medicine.

Causes of Tachycardia at Night


First of all, you need to make clear the following: what is it that makes me anxious? Is it that I’m just trying to repress a problem? Most often, anxiety due to events in life triggers the parasympathetic nervous system to increase life functions. In such a case, changes in hormone secretions take place according to the “fight or flight” principle: accelerate breathing, raise blood pressure, and heart rate. Also, this can not only result from conscious thoughts but also anxiety.


Let’s face it, alcohol affects the heart. Unfortunately, anyone who thinks a drink can help fall asleep is wrong. Because alcohol has a high sugar content and the metabolic processes that alcohol can provoke, it can speed up your pulse and lead to arrhythmias.

Worse scenario: if we drink alcohol before going to bed because we are in distress, these factors will add up, and we can expect even more severe consequences. Practically, we double the risk of palpitations, that is, the risk of a rapid heartbeat. Think about it.


Believe it or not, but too much sugar can accelerate the heart rate. It is advisable to avoid high sugar content foods before going to sleep. Many drink a glass of milk before bedtime, which, unfortunately, also high in sugar.

Glucose will quickly raise the heart rate. Also, the carbohydrates raise insulin secretion. Insulin increases adrenaline secretion, which further raises the pulse rate. It is, therefore, not wise to eat directly before bedtime.

Why the strong heartbeat dangerous?

Let me explain.

There is usually a simple case of the night’s heavy heartbeat with people who have a healthy cardiovascular system. At the same time, as age progresses, the chance is there for an increased atrial and ventricular arrhythmia, even if there is no sign of coronary heart disease.

So if you experience any arrhythmia, it is worth a cardiology visit. Scars on the heart muscles, for example, may cause bradycardia, slowed heartbeat, while other conditions may result in tachycardia. Therefore, patients with diagnosed cardiovascular disease should be checked regularly.

The doctor is examining the heart rhythm with an ECG. Arrhythmias that occur casually, cannot be observed as no symptoms of arrhythmias are present at the exam. Diagnosis involves inquiries for any possible symptoms such as breathing difficulty, tiredness, choking feeling in the chest, fainting, or nighttime high pulse.

What can I do to sleep better?

The answer might surprise you. It is easier than you think.

  • Get more sunlight during the day. Our brains are programmed to sleep when it’s dark and wake when it’s light. Not getting enough sunlight during the day will deprogram our biological clock. Once your circadian rhythm is disrupted, your brain won’t get the sleep signal when you are going to sleep.
  • Exercise during the day. Exercise relaxes the body and mind. Walk 30 minutes a day. If walking’s not your thing, try Yoga.
  • Have a hot bath before bedtime. The heat of the water relaxes the muscles, and also your body temperature will drop after the bath. The drop in body temperature sends a sleep signal to the brain.
  • Keep the temperature in your bedroom at 70 degrees F or below. An overheated bedroom is causing sleep problems. You can better relax with temperatures at 70 degrees.
  • Reduce your caffeine consumption in the evening. Otherwise, you will have difficulty falling asleep.
  • Reduce alcohol consumption. The result of drinking can be a disturbed sleep or difficulty falling asleep. Instead, try natural alternatives, such as valerian herbal tea.
  • Remove the TV and do not work in bed. Your brain slowly shuts down when about to go sleep, and any distraction will prevent it from sleeping.
  • Go to bed around the same time every day. It will be easier to fall asleep at the same time every day.
  • Sleep naked. Pajamas can be too warm, wrinkle, and crumble. It is much better to keep your body cool.
  • Take the alarm clock out from your view. Watching the time will make you anxious to sleep. Anxiety causes palpitation and prevents you from sleep. Losing the sense of time by not seeing the actual and not knowing how long you have been awake has shown to improve sleep and prevent living through the phenomenon of tachycardia at night.

By now you should sleep much better. However, if you aren’t satisfied with this content, you may talk to a professional right now.
