Heart racing at night: Causes and treatment

heart racing at nightYou may notice that your heart races at night or you experience more frequent heart palpitations. For some, this may actually be an all-day occurrence which is overlooked because you are just too busy during the day to notice. But by the time you relax at night, these symptoms become more apparent. Other people may actually experience changes in heart rate only at night or while falling asleep. So, what is going on exactly?

In a healthy adult, the heart rate should average between 60 and 100 beats per minute. Factors that determine heart rate are activity level, exertion of the body, and even stress levels. Throughout the day, our heartbeats may quicken or slow down. This is known as heart palpitations.


Heart palpitations can be harmless and merely a response to activity, stress, etc. But in some cases, they can be the sign of a serious condition. When it comes to matters of the heart, it’s best to be on guard to help prevent any serious illness.

10 Common Causes of heart racing at night

Nightmares or night terrors: A nightmare or night terror can be a scary occurrence. As a dream gets scarier it can increase your heart rate. Although many people may not remember their dreams or nightmares, they may wake up in a cold sweat or breathing heavily.

Emotional triggers: Anxiety, stress, or excitement can increase heart rate as there is a release of adrenaline in the body.

Hormonal changes during period, pregnancy, and menopause: Hormonal changes occur during a woman’s period, pregnancy, and menopause. These hormone fluctuations can cause the heart rate to speed up. As these changes are natural occurrences, in this case speeding up in the heart rate isn’t much to worry about.

Certain medications or substances: A side effect of certain medications can be heart palpitations. Many blood pressure and asthma medications can lead to a racing heart rate, especially if they are taken at night. Other substances that increase heart rate include spicy foods, alcohol, caffeine, nicotine, and recreational drugs.

Low blood pressure: Blood pressure usually lowers at rest, but if it is too low your heart rate will speed up to compensate.

Low blood sugar levels: Heart palpitations as a result of low blood sugar levels can be dangerous, as it can signify a complication. Other symptoms include dizziness, confusion, and shakiness. If blood sugar is not restored, the person may even faint. Low blood sugar levels can be due to exercise, a skipped meal, or too much insulin.

Heart disease: Heart racing at night could be a symptom of heart disease and may be associated with coronary artery disease or a previous heart attack or other problems with the heart muscle or valves.

Other health conditions: Hyperthyroidism (overactive thyroid), diabetes, anemia, high fever, and dehydration
