When is blood pressure the highest during a day?

Blood pressure in the morning and afternoon is generally higher than usual. For example, from 6:00 to 9:00 in the morning, the body's organs gradually wake up, and the speed of blood flow is faster than usual, so blood pressure tends to rise. This is also the reason why many patients are prone to stroke in the morning. Additionally, the issue of high blood pressure is also prone to occur from 4:00 to 6:00 in the afternoon.

After 6:00 in the morning, most people have just woken up for a short time. At this time, the organs in the body gradually start to wake up and resume normal function. The blood flow speed begins to increase, and blood pressure tends to rise rapidly. The sympathetic nervous system receives signals and becomes excited. The blood viscosity is also relatively high, and the dissolution of relative fibrinogen is insufficient. When the body switches from sleep to work, the brainstem cannot effectively counteract the rise in blood pressure.

During this period, blood pressure will reach another peak. The afternoon is also a time when the human body's metabolism is relatively fast. At this time, people's energy and work efficiency are not particularly strong, and they are generally more tired, which is a normal reaction of the biological clock. In the afternoon, the secretion of excitatory adrenaline increases, and blood pressure tends to rise. The amount of exercise in the afternoon is relatively large, and the blood flow rate is also faster.
