Why sleep at night when palpitations

Sleep palpitations at night may be caused by physiological factors, hyperthyroidism, obstructive sleep apnea, etc.

1. Physiological factors

If the patient has too much stress, insomnia, emotional tension, etc. in the near future, it will lead to sympathetic excitation and increased secretion of dopamine substances when sleeping at night, thus causing palpitations.

2. Hyperthyroidism

When suffering from hyperthyroidism, due to excessive secretion of thyroid hormones in the body, metabolism will accelerate at night, heart rate will increase, and palpitations will occur.

3. Obstructive sleep apnea

Due to repeated collapse and obstruction of the upper airway during sleep, hypoxia will occur during sleep, resulting in insufficient oxygen supply to the heart, which will cause palpitations.
