Circadian Rhythm

The Circadian Rhythm is basically a 24 hour clock within the human body that regulates the wake and sleep cycle of the human body.

The Circadian Rhythym regulates physiological, behavioural and biochemical response within the body to ensure that a person maintains an adquate amount of sleep. This is why shift workers often find it so difficult to sleep during the day, even though they have been awake all night.

As a result of the Circadian Rhythm, a person’s heart rate, blood pressure and overall muscle relaxation will be slowest at approximately 2-3 am.
