Common causes of high blood pressure at night include poor sleep quality, staying up late, suffering from sleep apnea syndrome, taking short-acting antihypertensive drugs, and people with diabetes.
1. Poor sleep quality at night: dreaming after falling asleep, waking up easily after falling asleep, or insomnia all make the body in the awake state, leading to sympathetic nerve excitation, resulting in high blood pressure at night.
2. Staying up late: some people often stay up late to work, play games and so on. So that the body is in a constant state of tension, the sympathetic nerve continues to inhibit the vagus nerve excitation, resulting in high blood pressure at night.
3. Suffering from sleep apnea syndrome: due to repeatedly being in the condition of hypoxia, the body’s defense mechanism in order to alleviate hypoxia, it will increase the activity of the sympathetic nervous system by increasing the stimulation of the sympathetic nervous system, thereby increasing the heart rate, cardiac muscle contraction, resulting in higher blood pressure.
4. Taking short-acting antihypertensive drugs: It is also possible that hypertensive patients are taking short-acting antihypertensive drugs during the day, and the effect of the drugs passes at night, leading to higher blood pressure at night.
If you find high blood pressure at night, you should consult a specialist in time to rule out abnormalities, so as not to delay the condition.
