We spend 1/3 of our lives working, 1/3 of our lives relaxing or doing housework, and 1/3 of our lives sleeping, so sleep is an important part of life. Now more and more studies have found that sleeping position is significantly related to sleep quality. Many friends do not take this conclusion seriously, thinking how comfortable how to sleep, never considered that sleeping position is also related to our health. In recent years, with the increasing incidence of hypertension, through multi-factor analysis found that sleep posture and the occurrence of hypertension has a close relationship, especially the study of sleep apnea syndrome, a large number of clinical observations and experimental studies at home and abroad, has proved that sleep apnea syndrome is one of the important factors causing the occurrence of hypertension, but also one of the reasons why hypertension can not be well controlled. We first understand some general knowledge of sleeping posture. According to the survey 60% of people are used to sleeping on their backs, 35% are used to sleeping in the lateral position, while 5% are used to prone sleep. Any kind of sleeping position has its advantages and disadvantages, some people say that people with heart disease should not lie on the left side, the actual situation is that the heart is located in the chest cavity, protected by the chest cavity, so the heart will not be significantly compressed when lying on the left side, and clinical medical observation also found that the incidence of heart disease in people who are used to sleeping on the left side is significantly lower than in people who are used to sleeping on the right side. Most people who are used to sleeping on their backs will say, “I can easily fall asleep in this position and sleep solidly, so it seems that sleeping position varies from person to person, there is no absolute good or bad, we can rest assured that the natural way to sleep, no need to deliberately pursue a certain sleeping position, as long as it can make the body relaxed. However, modern research on the relationship between sleep and disease shows that sleeping posture is significantly related to the occurrence of disease, especially hypertension and sleeping posture have a significant relationship, so what kind of sleeping posture should be taken to be good for blood pressure? Let’s start with the sleeping position of the fetus. In October, the fetus sleeps in the womb for 10 months, and her sleeping position is the most natural and most consistent with the natural human sleeping position, regardless of the standing or horizontal position, the fetus is in a bent legs and forward head position, so the best sleeping position is fetal-like sleep. Recent studies have proved that the correct sleeping position should be right side lying with legs slightly flexed, so that the heart is in a high position and not compressed, the liver is in a low position, which is conducive to liver blood circulation, the liver’s catabolism is vigorous, the food in the stomach with gravity, towards the small intestine, which can promote digestion and absorption, while the whole body is in a relaxed state, breathing evenly, heart rate is stable, the brain, heart and lungs, gastrointestinal, muscles and bones get Adequate rest, so that the metabolism is more optimal. A clinical experiment was conducted in China, in which hypertensive patients with mild, moderate and severe snoring were selected and their blood pressure was continuously monitored. This led to the conclusion that the degree of snoring was significantly associated with increased blood pressure. In a study conducted in the United States to observe the relationship between sleep and hypertension, two groups of patients with sleep apnea syndrome with comparable blood pressure levels were selected, one group applied positive pressure ventilation ventilator to assist breathing during nighttime sleep, and the other group slept naturally without ventilator, and both groups measured blood pressure with ambulatory blood pressure monitor. The average blood pressure in the group with positive pressure ventilation was significantly lower than that in the group without ventilator, and the quality of sleep was also better. They observed different groups of people sleeping in supine, lateral and prone positions, and used dynamic EEG, pulse oximetry, heart rate and blood pressure monitor to observe the effects of different sleeping positions on the above physiological indicators, as well as to observe the presence of dizziness, headache and other symptoms, and the conclusion was that the group resting in the lateral position had the least change in EEG The group who sleep in the supine position has the least fluctuation of brain waves, most of the blood oxygen saturation is normal, heart rate and blood pressure are stable, and the incidence of dizziness and headache is the lowest; those who sleep in the supine position have fluctuation of brain waves, blood oxygen saturation is often low, heart rate increases with the decrease of blood oxygen saturation, blood pressure also increases, and the incidence of dizziness and headache is the most; those who sleep in the prone position have the most obvious fluctuation of brain waves, sleep is unstable, and cannot maintain this position for a long time. Sleeping position, heart rate, blood pressure changes more, blood oxygen saturation is unstable, heart rate, blood pressure changes more, blood oxygen saturation is unstable, the incidence of dizziness, head swelling and other symptoms in the middle. From this test, we conclude that the brain can be fully rested by sleeping in the lateral position, breathing evenly, and the heart rate and blood pressure are closest to the physiological changes in the normal resting state, supporting that sleeping in the lateral position is good for blood pressure. We then analyze the relationship between sleep position and hypertension mechanistically. When sleeping in the wrong position or poor sleep, the cerebral cortex is always excited, activating the renin-angiotensin-aldosterone system, while the excitability of the sympathetic nervous system is also elevated, causing hypertension; incorrect sleeping position, it is easy to have an unobstructed airway, incomplete obstruction, or even apnea, causing severe hypoxemia, reflexively causing an increase in heart rate In addition, blood pressure increases; the brain is deprived of oxygen, insufficient blood supply causes dizziness, dizziness and other symptoms; long-term lack of oxygen will also cause metabolic disorders, endocrine disorders, instability of the nervous system, and even tension, insomnia, anxiety and other conditions, which in turn will accelerate the rise in blood pressure, instability. In summary, the sleep position and the occurrence of hypertension has a certain causal relationship, the correct sleeping position for friends with hypertension is a kind of adjustable, blood pressure stabilization measures, should attract full attention, not how comfortable so sleep; correct, scientific sleep position should be side rest, this sleeping position blood pressure, heart rate and other physiological indicators of the most stable, can also improve the improper sleeping position due to And dizziness, head swelling and other symptoms caused by improper sleeping posture, for hypertensive friends is really beneficial.
