The heart grows on the left side of the chest cavity, does sleeping on the left side affect the heart? Who can’t sleep like this

Does the left side sleep oppress the heart is unhealthy? When I was a child, my grandmother always reminded me to sleep flat, with feet straight to grow taller. He also said, don’t fall asleep to the left, otherwise your heart will be crushed. So, when I was young, I would always sleep with my feet straight, even if I turned over, I would lie to the right. When I grew up and learned medicine, I knew that these statements were totally untenable. The heart is not as fragile as imagined. It does not care where you sleep. The human blood vessels are like an extremely complicated network. Blood flows through the entire vascular network. The blood vessels are elastic. When the human body takes different postures, the blood in the body will Reassign. For example, when standing, most of the blood is concentrated in the lower limbs due to gravity. When lying down, the blood stored in the lower limbs returns to the heart. At this time, the amount of blood returned to the heart will increase, increasing the burden on the heart. If you sleep to the left , The heart is lower, the amount of blood returned will be more. However, when a person sleeps, he does not keep one posture unchanged, and will switch between different postures. For people with normal heart function, the left lateral position has a negligible impact on the heart. Activities such as running or climbing stairs increase the load on the heart far more than the effect of sleeping to the left on the heart. Therefore, there is no scientific basis for the claim that sleeping to the left will oppress the heart and cause unhealthy health. For a healthy adult, no matter what sleeping position, as long as you feel comfortable. However, there are several types of people who need to pay attention to their posture during sleep. 1. Patients with gastritis, gastritis, gastric ulcer, gastroesophageal reflux, etc., it is best to sleep on the right side, because this sleeping position will not compress the heart or the stomach, which is conducive to the digestion of food in the stomach. Can prevent stomach acid reflux caused by stomach squeeze. 2. Heart disease patients For heart disease patients, when they sleep on the left side, the heart is lower, the amount of blood returned to the heart will be more, the heart will be heavier, and there may be uncomfortable feelings such as suffocation. Especially for patients with heart failure, try not to lie on the left side, but should sleep in a head-high, foot-low, semi-recumbent position, and reduce the return of blood by gravity. 3. People who are used to snoring are best to use the lateral position. When the air enters the lungs through the nasopharynx and trachea, if the pharynx and nose are narrowed due to rhinitis and turbinate hypertrophy, the air enters these narrow parts. It is prone to snoring. In addition, the airway of the pharynx is at the base of the tongue. When sleeping, the tongue muscles are in a relaxed state. If you take a supine position, the relaxed muscles will fall back under the force of gravity, which will cause the pharynx to narrow and make it easier to snore. Therefore, there are respiratory diseases such as bronchitis and rhinitis. In order to alleviate the symptoms, it is generally recommended to use the lateral position. 4. Pregnant women doctors generally recommend that pregnant women sleep on their left side. This sleeping position can turn the right-handed uterus into a straight position, reduce the risk of abnormal fetal position and childbirth, and avoid the uterine compression of the inferior vena cava. Heart blood discharge, improve blood perfusion of the uterus and placenta, and reduce lower extremity edema.

Pay attention to the following points during pregnancy!

1. Do not take medicines for colds. Anti-inflammatory drugs are contraindicated for pregnant women. In addition, pregnant women with colds do not have clear evidence of bacterial infections, such as tonsillitis, high blood pressure, yellow sputum, and runny nose. Expectorants and cough suppressants are generally safer, but antitussives containing iodine preparations should not be used by pregnant women. 2. Pregnant women diarrhea care Pregnant women diarrhea may cause miscarriage or premature delivery. First of all, don’t eat anything for a while. Proper rehydration to make up for the water and electrolytes lost due to diarrhea, especially potassium ions, but also to add lost calories. It is possible to prepare pregnant women with some fluid-digestible porridge. If it is not very serious, an empty stomach will be fine. While rehydrating, it is necessary to closely observe whether the fetus is in good condition, and whether there are signs of miscarriage or premature delivery. If the condition of the fetus is abnormal, you should go to the hospital immediately without care. 3. Correct sleeping posture during pregnancy In early pregnancy (1 to 3 months), the sleeping posture of pregnant women can be random, mainly in a comfortable posture, such as supine position and lateral position. Bad sleeping positions such as sleeping on your stomach or arms around should be changed. During the second trimester of pregnancy (4 to 7 months), care should be taken to protect the abdomen during this period to avoid the direct effect of external forces. If the pregnant woman has too much amniotic fluid or twin pregnancy, it is necessary to adopt a lateral sleeping position, which can make the pregnant woman more comfortable. If the pregnant woman feels heavy lower limbs, you can take a supine position and raise the lower limbs with a soft pillow. In the third trimester of pregnancy (8 to 10 months), it is advisable to adopt a left lateral position during this period. This type of reclining position can correct the right hand rotation of the enlarged uterus, reduce the pressure of the uterus on the abdominal aorta and iliac artery, and increase the supply to the fetus Blood volume is conducive to the growth and development of the fetus. 4. When taking a bath, pay attention to the bath. Due to poor ventilation, turbid air, and high humidity in the bathroom, the oxygen content in the air will be reduced. In addition, the stimulation of hot water will cause the blood vessels in the body to dilate, causing fainting during bathing. Happening. If the pregnant woman takes too long to take a bath, in addition to the above, it will also cause fetal hypoxia. Therefore, it is generally not advisable for pregnant women to take a bath for more than 15 minutes at a time, or to prevent dizziness and chest tightness among pregnant women themselves. 5. Precautions for pregnant women to watch TV Avoid watching TV for a long time. Generally, pregnant mothers should not watch TV more than 2 hours at a time to avoid excessive use of eyes, especially pregnant mothers with pregnancy-induced hypertension syndrome. Avoid watching horror, nervous, tragic programs, these programs will make pregnant mommy emotionally nervous, a special substance appears in the blood, brought to the fetus through the placenta, making the fetus uneasy.
