1. will not affect. Which way to sleep depends on your sleeping habits. Everyone may be different and have no fixed orientation. At present, there is no scientific basis to prove that orientation is harmful to human body, so don't worry too much. But if you feel dizzy or tired when you sleep with your head facing west, which seriously affects your sleep quality, I suggest you sleep in another direction and see if the situation has improved. When sleeping, the orientation of the head has no effect on the body. Come when you feel comfortable, mainly depending on your sleep habits.
Because the orientation of your head is determined according to your sleeping habits, so be careful not to sleep in the direction of the window mouth, lest you wake up the next day and find your mouth crooked. Uncomfortable symptoms, such as dizziness and low back pain, may also be caused by sleeping position. When people sleep on their backs, the contact surface between the limbs and the bed is the largest, which is not easy to backache, and is beneficial to the blood circulation of the brain and limbs. When people sleep in the right lateral position, because the stomach outlet is at the bottom, it is helpful to promote the discharge of stomach contents. However, sleeping on the right side for a long time will oppress the right limb, affect the local blood return, and may cause numbness, pain and other discomfort. Lying on the left side for a long time is not conducive to blood circulation, and may also increase the pressure of the heart on the chest. Therefore, it is recommended to change your sleeping position frequently.
3. I will find that when I sleep, I may be so particular, not particularly scientific. We usually think that sleeping habits or a certain state are good, and we can choose according to our own habits and States, which is better for our health. In normal times, we should focus on our habits and comfort, because in this way, we can sleep better. Our mental state is better. Everyone has his own habits, so people with different habits have different States. Sleeping on the right side is good for human health, because the heart is on the left side of the chest. Lying on the right side can relax the muscles of the whole body, and the heart and chest are not squeezed, so that people can breathe smoothly, thus ensuring the oxygen supply of the whole body during sleep.
