Sleeping is probably the biggest thing in daily life besides eating, so it is natural to become one of the topics that are never absent after tea.
Since I was a child, I have heard people say that sleep is directional, and I have listened to it for more than thirty years, so what is the best direction for sleeping? If you ask why, it is either related to the Earth's magnetic field or to the prosperity of the family. Sleep can not be eastward, is this science or superstition? First of all, let's talk about the facts, let's talk about the theory, the fact is that I am sleeping in an east-west direction, with my head facing east and my feet facing west, and I have been sleeping for five years, closing my eyes at night and falling asleep quickly, opening my eyes in the morning, and never feeling that sleep has been affected in the slightest by the orientation. As for the direction of sleep will affect the prosperity of the family, it is even more nonsense.
So is the direction of sleep theoretically related to the Earth's magnetic field?
First of all, let's talk about what is the Earth's magnetic field, and how the Earth's magnetic field is generated. Regarding the generation of the Earth's magnetic field, scientists do not yet have a satisfactory answer, so the scientific community has proposed many different hypotheses, the more well-known internal current theory, the charge rotation theory, the piezoelectric effect theory, etc., but one thing is certain, that is, the Earth's magnetic field is essentially an electromagnetic field, which is a magnetic field generated by the current effect of the electrons rotating with the earth through the outer core. From this we can also know that the generation of the Earth's magnetic field is closely related to the lava activity in the Earth's interior. The Earth is like an egg, the hard part of the crust we come into contact with is actually very thin, and the earth's interior is full of flowable lava material.
In the earth's core, there is a convection of iron and nickel, and this convection creates a magnetic field under the action of the Coriolis force.
Since the Earth has a magnetic field, what is the direction of the magnetic field? We are accustomed to saying north-south, east-west, but it is not accurate to use these words to describe the direction of the Earth's magnetic field, because geographic poles and magnetic poles are not the same thing. The Earth's magnetic north pole is in the south, and the magnetic south pole is in the north, but the magnetic north pole does not coincide with the geographical south pole, but only near the geographical south pole, and the magnetic south pole does not coincide with the geographical north pole, and is also only near the geographical north pole. Since the magnetic poles are not due south or north, the so-called north-south sleeping direction is not completely in line with the direction of the Earth's magnetic field. Moreover, the distribution of the Earth's magnetic field lines is not the same in different regions.
Near the equator, the direction of the Earth's magnetic field is horizontal, while in the polar region, the direction of the magnetic field is perpendicular to the surface, and the most important thing is that the magnetic field on the Earth's surface will change at any time due to the influence of various factors.
Therefore, if you really want to adapt the direction of sleep to the earth's magnetic field, then you must flexibly adjust the direction of sleep according to your geographical location, rather than simply using "east-west" or "north-south" to define. The Earth's magnetic field is far more complex than we think, in fact, not only will the magnetic field on the Earth's surface change due to various factors, but even the magnetic poles will move and even flip. Why is the magnetic north pole near the south pole and the magnetic south pole near the north pole? This is not constant, and french scientist Brunette found that about 700,000 years ago, the Earth's magnetic field underwent a reversal.
The reversal of the Earth's magnetic field 700,000 years ago was not the first, and certainly will not be the last, and scientists believe that the reversal of the Earth's magnetic field is cyclical.
It can be seen that the change of the earth's magnetic field is unpredictable, so there has never been any statement that adjusts the direction of sleep according to the magnetic field, so does the magnetic field have an impact on sleep? Theoretically, the human body can also be regarded as a small magnetic field, theoretically sleeping in the direction of the Earth's magnetic field lines can indeed reduce the interference of the Earth's magnetic field, but this interference itself is minimal, unless you have serious sleep disorders, then sleeping in the direction of the Earth's magnetic field may feel a little different, but for ordinary people, sleeping in which direction has no impact. It is worth mentioning that sleeping in the north-south direction does not fully conform to the direction of the Earth's magnetic field.
In fact, compared to the direction of sleep, there are many ways to improve the quality of sleep more effectively.
The factor that affects sleep the most is the sleep environment, and the biggest factor in the sleep environment is temperature and humidity, scientific research has found that the most comfortable sleep temperature is 26 degrees Celsius, and the optimal sleep humidity is between 30% and 80%. Then there is the light, and closing the blackout curtains to create a dark environment is also helpful for improving the quality of sleep. As for the sleeping position, in fact, it is the same as the direction of sleep, there is no need to be too entangled, everyone's situation is different, some of the best sleeping positions for some people, but how to sleep, so choose a position that makes you feel the most comfortable, the easiest to fall asleep can be, the most suitable is the best.
