Does circadian rhythm affect heart rate?

Several studies have reported that the circadian clock influences important CVD risk factors such as heart rate and blood pressure [1, 11, 18]. Circadian misalignment, even when short-term, can increase 24-hour blood pressure and decrease parasympathetic activity [23].
