What does it mean when you wake up with a racing heart?
Waking up with a racing heart can be confusing and scary, but it is rarely a cause for concern. Many factors can cause a person to wake up with a racing heart, including diet, stress, sleep deprivation, and arrhythmia.
Sometimes, upon waking, it may feel as though the heart is beating very fast or pounding in the chest. A person may also feel shaky or anxious when this happens.
A racing heart may feel similar to heart palpitations or arrhythmia. Although this might feel worrying, it is typically linked to everyday factors such as anxiety and diet, and it is usually only temporary.
A person may also wake up with a racing heart due to the presence of a medical condition, such as diabetes, a sleep disorder, or anemia.
People who experience this regularly may want to check in with their doctor, who will be able to determine or treat the underlying cause.
