In ancient times, the bed under the beam was called "beam bed", which means that the position of the bed from the head of the bed to the end of the bed is just opposite to the beam cross of the house where you live. Generally, beams are arranged in the east-west direction, while beds are arranged in the north-south direction. The beams are arranged in the east-west direction, and the head and feet sleep in the north and south. The weight of the whole house is on the sleeper, and life is getting harder and harder.

Ancient health experts in China believed that people's sleeping direction should change with the alternation of spring, summer, autumn and winter. "When you are busy at four o'clock, you lie down", and the direction of sleep also corresponds to the solar terms at that time. Therefore, there are theories about the orientation of the bedside when sleeping, such as spring east, summer south, autumn west and winter north.
Looking up relevant information, it is found that people have endless opinions on the problem of bedside orientation. In addition to seasonal changes, some people think that the bedside should not face west, because this will make the direction of human body position movement opposite to the direction of the earth's rotation, making the human body feel uncomfortable.
It is also said that the human body should sleep with its head facing north and its feet facing south, which is consistent with the direction of the earth's magnetic field. This kind of sleep mode in line with the direction of the earth's magnetic field can reduce the influence of geomagnetic field on human body, thus helping people to keep a good sleep. But according to experts, all these statements have no scientific basis.
Sun Simiao, a medical scientist in the Tang Dynasty, also said in "Thousands of Women": "Ordinary people lie down, facing east in spring and summer, and facing west in autumn and winter. Don't lie on your back or sleep on the north side of the wall. " Due to the limitations of ancient people's understanding, this statement is unscientific. Sleep is related to many factors, such as mood and psychology, and it is not just changing the orientation of sleep that can solve the problem of sleep disorder.
Although it is meaningless to change the orientation of the bedside to improve the quality of sleep, it is helpful to provide yourself with a comfortable and quiet natural environment for high-quality sleep.
Grasping the temperature and light in the bedroom will help you have a good sleep. People's body temperature will automatically adjust according to the biological clock. At night, the human body enters a quiet state, and the body temperature will also drop. It is generally believed that 23℃ is the best sleeping temperature, at which people feel the warmest and most comfortable.
In addition, indoor humidity also has a certain impact on sleep quality, but the human body will gradually adapt to the environment over time, and it will not have a significant impact after a long time. It is suggested that the temperature and humidity should be adjusted to a comfortable standard according to personal conditions.
The darker the light, the more helpful it is to sleep. If you want to have a good sleep, it is best to reduce the brightness of the whole room before going to bed, so that the brain can gradually accept a slightly dark environment and enter the preparation period of sleep, which will help relieve insomnia. In addition, it is recommended to choose light pink, light blue and other colors that make people feel relaxed and quiet, rather than red and other colors that make people nervous.
For people with high requirements for sleeping environment, the overall color system of the bedroom will also have an impact on sleeping conditions. It is generally believed that beige and light blue are the most helpful for sleep. Beige is the mildest of all colors and is suitable for use in the bedroom. Blue can relieve tension. People who are prone to insomnia, it is best not to use colorful and complicated wallpaper in the bedroom.
The comfort of pillow has a certain influence on sleep quality. When choosing a pillow, you should pay attention to softness, breathability and height. Don't care too much about materials and don't be confused by some concepts. The human body has an adaptability to pillows, and a good pillow should be consistent with your accustomed sleeping position.
There are three elements of healthy sleep, including sleep duration (7 hours for adults), sleep timing (falling asleep the night before) and sleep quality (normal sleep structure).
The basis of healthy sleep should be mental health, happiness and the law of life. It is suggested that the quality of sleep can be improved by doing more outdoor activities, eating regularly and using drugs reasonably. If necessary, you should seek medical attention in time, find out the reasons and improve your sleep by scientific methods.
