During the day, it is generally more accurate to measure blood pressure in the morning when you have just woken up and are not active, and at bedtime when you are well rested and relaxed.
For the human body’s blood pressure, 24 hours a day, is not fixed, but there are certain changes fluctuations. Generally speaking, blood pressure is higher during the day and lower at night; and during the day, 6-8 a.m. and 4-6 p.m. are the peak stages of high blood pressure. Blood pressure at this time will be high, but generally should not exceed the normal value of blood pressure.
Generally speaking, the normal values of blood pressure are diastolic blood pressure 60-79 mmHg and systolic blood pressure 90-119 mmHg. If the diastolic blood pressure is ≥90 mmHg and/or systolic blood pressure ≥140 mmHg three times in the non-same day, then it is classified as high blood pressure.
Blood pressure is also affected by exercise, emotional excitement, and food stimuli such as smoking, drinking alcohol and coffee.
In order to more accurately reflect the body’s blood pressure status, it is recommended to measure blood pressure in the morning when you have just woken up and are not active; before going to bed, when you are well rested and relaxed, so as to minimize the interference of related factors.
If your blood pressure is found to be over the limit after measurement, you should consult a doctor, have it checked again, and follow the doctor’s instructions for treatment.
