How are heart rate and sleep quality related?

It has been shown that heart rate is significantly higher in the morning after a night of poor sleep and long-term poor sleep is associated with overall elevated heart rate. Heart rate patterns have also been identified in good sleepers. At the onset of sleep, heart rate decreases and remains lower to meet the reduced metabolic needs of the body during rest. Tracking heart rate in the morning, during the day, and before bed will build a clear picture of sleep quality. A lower heart rate in the morning, followed by a slightly increased (normal) daytime heart rate, followed by a reduced heart rate before bed, indicates good sleep quality.
