When is blood pressure high in a day

summary

In order to master the blood pressure and self judge the efficacy of antihypertensive drugs, patients with hypertension should often measure their blood pressure at home. It has been proved that self-monitoring blood pressure can reflect blood pressure more objectively than clinic pressure measurement. So when is the best time to measure blood pressure every day? Most people's blood pressure shows obvious circadian rhythm, that is, the blood pressure is higher in daytime activity state, and lower at night after falling asleep. Generally, there are two peaks in daytime blood pressure, namely 6-10 am and 4-8 PM. Therefore, it is necessary to measure blood pressure in these two periods to know the highest point of blood pressure in a day.

When is blood pressure high in a day

First: blood pressure is measured every morning when you wake up. At this time, the blood pressure level reflects whether the antihypertensive effect of drugs can last until the next morning. If the blood pressure is very high in the morning, 24-hour ambulatory blood pressure should be measured in order to understand the sleep state of blood pressure. If the blood pressure during night sleep is the same as that during the day, antihypertensive drugs should be taken before going to bed; if the blood pressure during night sleep is very low and the blood pressure rises suddenly in the morning, antihypertensive drugs should be taken in advance when you wake up or even at 3-5 o'clock in the morning.

Second: blood pressure was measured 2-6 hours after taking antihypertensive drugs. Because the short acting preparations usually reach the maximum antihypertensive effect 2 hours after taking medicine, the peaks of antihypertensive effect of medium acting and long acting preparations appear 2-4 and 3-6 hours after taking medicine respectively, and the pressure measurement at this time basically reflects the maximum antihypertensive effect of drugs.

Third: the best time to measure blood pressure is within 1 hour after getting up in the morning or before going to bed in the evening. If the morning measurement, please wake up within 1 hour, after urination, before breakfast (if you are taking antihypertensive drugs, then before taking medicine). If the measurement is done at night, it is recommended to do it before bedtime. If it's any other time, it's better to measure when both body and mood are stable. In addition, it is recommended to measure at the same time every day.

matters needing attention

① The causes of blood pressure changes are: movement, mental state, emotion, diet, drinking, urination, defecation, conversation, environmental changes, temperature changes, smoking and so on. The blood pressure was the highest at work, and gradually decreased in the afternoon and evening. The blood pressure was lower during sleep and gradually increased after getting up. ② Blood pressure measured at home may be lower than that measured in hospitals and medical institutions. This is because it is easy to be nervous in the hospital and relax at home. It's important to know the blood pressure in a stable state at home. ③ The blood pressure of wrist may be different from that of upper arm. The blood pressure measurement of wrist may be slightly different from that of upper arm due to the difference of measurement position and blood vessel thickness. In most cases, the highest and lowest blood pressure of healthy people have a difference of about 10 mmHg. ④ Please rest for at least 5 minutes before measuring. Please measure quietly in a relaxed state. Please measure at about 20 ℃.
