Why can't you sleep with your head facing east and your feet facing west? Can't sleep on the left? Is there any scientific evidence?

People spend one third of their life sleeping. Like eating, sleep is a basic physiological need of ours, and it is also an important way for us to repair and replenish our physical strength.

When we are in a state of sleep, our brain and body will be rested, rested and recovered. A good sleep is very helpful for our daily work and study. Therefore, improving sleep quality has become an important guarantee for people to work and live better. For the student party who often engages in mental activities, sleep is still a key period in the day to consolidate memory, and only if you sleep well can you remember.

Our physical fitness and even our longevity are inextricably linked to the quality of sleep. When you sleep the deepest, it is also a period of accelerated release of immune substances in the human body. It can be said that sleeping well can improve the immunity of the body and enhance the body's ability to prevent, resist and recover from diseases.

Sleep health deserves attention and has sparked a lot of discussions. For example, there are often sayings that "you can't sleep with your head facing east and your feet facing west", and there are also sayings that you can't sleep with your left face, so are these statements consistent with science? Is it worth doing?

Can't sleep with head facing east and feet facing west?

Some people say, "If you want to sleep easily, don't turn your head to the west and your feet to the east." Because the direction of the earth's magnetic field is north-south, sleeping in the south or north is in the direction of the earth's magnetic field, so it is easier to fall asleep. The head facing east and the feet facing west are wearing the earth's magnetic field, so they will not get the bonus of the magnetic field, but will be affected by the magnetic field and cause insomnia.

In fact, the earth's magnetic field is not completely north-south, and has a certain inclination angle. On the other hand, it is not easy for us to maintain a north-south sleeping position, because the houses we live in are rarely built according to the north-south direction. Yes, in order to ensure sleep in the north-south direction, do our beds have to be placed diagonally in the house? This is obviously impractical.

What's more, the earth's magnetic field at each point will change at any time, and sleep completely according to the magnetic field. I am afraid that you need a bed that can adjust the angle at any time. If you do this, it will be more likely to cause insomnia. What's more, the jury is still out on whether the Earth's magnetic field has any effect on sleep or even health. "Don't turn your head to the west and your feet to the east" does not seem to be reliable.

Can't sleep on your side to your left?

The reason for claiming that you can't sleep on your left side while sleeping is that the heart is located on the left side of our body.

In fact, the heart, as our most important organ, is heavily protected in the human body. The heart in the thoracic cavity is firmly fixed, supported and surrounded by our ribs. Even if we sleep on the left side, the heart is affected by The impact is also negligible.

Only those who have hidden heart problems need to avoid sleeping on the left side as much as possible, because their hearts are inherently more fragile, and a small impact may have certain consequences.

In fact, various sleeping positions have pros and cons. Although lateral sleeping may not necessarily compress the heart, for children in the growing stage, it will affect the bones and increase the risk of scoliosis. For fully developed, healthy adults, it's just a matter of choosing a sleeping position that you're used to.
