The supine position is suitable for the body. When people lie down, the pressure and resistance of blood flow will be reduced, which is equivalent to reducing too much pressure on the heart. But if the heart function is not good, this sleeping position is not good, so it is important to pay attention to whether the body is healthy or not. In particular, the heart is unscathed, and maintaining this sleeping position can support the blood of lower limbs and upper limbs. It can return to the heart in a short time and meet the blood supply to the brain, so it is helpful to the body.
Cardiopulmonary problems are in a semi-recumbent position. If it is a heart problem, the corresponding lungs also have problems, so in order not to bring some burden to the body, especially the workload of the heart, we must learn to reduce it. On the one hand, if you lie flat, blood will accumulate in the heart, making it difficult for the heart to breathe for a while. On the other hand, if it is in a semi-recumbent state, it will have enough time and space to work for the heart and lungs, so there will be no danger of insufficient oxygen in the body.
The lateral position protects the affected limb. Some people have cysts or other lesions due to problems in their body parts. At this time, you should learn to lie on your side, that is, you can't oppress your affected side, so as to relieve the pain and protect the affected side. In addition, please note that when you sleep at night, you can improve your sleep quality by alternately sleeping in several positions.
