The difference between morning and evening blood pressure is closely related to the basal blood pressure, and usually the difference between morning and evening blood pressure in normal people is between 10 and 20 mmHg. 24-hour dynamic monitoring of blood pressure in normal people reveals that the rhythm of blood pressure shows a double-peak and double-trough curve. The peaks of blood pressure are usually around 8 to 10 o’clock in the daytime and around 4 to 6 o’clock in the afternoon, while the troughs are around 2 to 3 o’clock in the late afternoon and 2 to 3 o’clock in the early morning. Nighttime blood pressure is usually lower than daytime blood pressure because physical activity and emotional fluctuations during the day will affect the blood pressure value, appearing high blood pressure, while the body is at rest at night, the blood pressure will fall compared to the daytime blood pressure. If the patient is not feeling well, it is recommended to go to the hospital in time for consultation and treatment.
