VARIATIONS IN BLOOD PRESSURE
Blood pressure is influenced by many factors and can change from moment to moment. Normally, blood pressure is lowest during sleeping periods and rises during the day. The graph below represents variations in blood pressure shown over a day with measurements taken every 5 minutes.
The dotted line represents the sleep period. The rise in blood pressure at 1pm (A in the graph) corresponds to a stressful occurrence and at 7 pm (B in the graph) a period of exercise.
