Presented are concepts for managing a blood-pressure variation of a patient. One such concept provides a method comprises the step of determining a target exercise intensity for the patient based on an obtained measure of diurnal blood pressure dip of the patient. The method also comprises determining a target exercise timing for the patient based on an obtained measure of the circadian rhythm thepatient. In this way, a target exercise intensity and target exercise timing may be determined and communicated to the patient for the purpose of managing or controlling a blood pressure variation through the combined timing and intensity of physical exercise.
