Optimal Times for Blood Pressure, Body Temperature & Pulse – What's Normal?

Blood pressure: Blood pressure typically peaks in the late morning or early afternoon and is lowest at night. This pattern is known as the circadian rhythm of blood pressure.

Body temperature: Body temperature is typically lowest in the early morning and highest in the late afternoon or early evening. This pattern is also known as the circadian rhythm of body temperature.
