Why do I wake up in the middle of the night, and have low blood pressure when I check?

Don't worry. Blood pressure usually is lowest late evening and with early sleep. Paradoxically, it raises in the early morning (7am-10am). This is called arousal activation of the nervous system. Don't worry, unless you have sx. Also, if you are on BP meds, many are evening dosed to prevent the moring rise!
