When is the highest blood pressure in a day?

During the day, blood pressure should be highest between 6:00 a.m. and 10:00 a.m., and there is a time period between 4:00 p.m. and 8:00 p.m., while blood pressure at night is often the lowest time of the day. For people with hypertension, a low-salt, low-fat diet is recommended to help control blood pressure.
