After the winter solstice, rural people began to enter the "cat winter" stage, but the rural houses are not as good as the buildings in the city, even if the doors and windows are closed, the room can still feel the cold wind, the air conditioning in the room is reluctant to open, the briquette stove has become the "magic weapon" to keep out the cold, in recent years, the village has innovated and planted grapes, many people take advantage of the warm hours of the day, to the park to apply winter fertilizer, the old people in the village will also catch up in the sunny afternoon, gather together to chat, older, the discussion is not some longevity topics, there is an old saying" Three inches of longevity, four inches of worry-free", what does this mean?
For the topic of longevity, many people say that they should be optimistic, don't worry about it, eat coarse tea and light rice, don't have to pursue too much, insist on exercising, and maintain a healthy body, and what does "three inches of longevity, four inches of worry-free" refer to?In fact, this colloquial phrase refers to sleep, and scientific studies have shown that adequate sleep is one of the keys to longevity. Sleep allows the body to get sufficient rest and repair, and at the same time, it can also improve the body's immunity and enhance resistance, thereby prolonging life.
In addition to a quiet room, there should be a comfortable bed, with quilts, pillows, mattresses, etc., so that the human body can sleep peacefully, but sleep only in deep sleep can be conducive to the recovery of body functions, light sleep or dreaminess is not conducive to physical health, in which the height of the pillow is one of the factors affecting sleep.
As the saying goes, "three inches of longevity, four inches of worry-free" of "three inches" and "four inches" refers to the height of the pillow, the proportion of the human body is verified, and the vertical distance from the cervical spine to the back of the head is about 10 cm, that is, "three inches", so that the human body lies on it, in order to help the whole body relax, not to the body or head at a certain point to support the gravity of the whole body, resulting in the body sleeping more and more tired, and even suddenly waking up, for a long time, mental fatigue, frail and sickly, but not conducive to longevity.
"Four inches" also means the height of the pillow, which means that the height of the pillow can not exceed four inches, so that longevity is not to worry, because the height of four inches is about **14 cm, which is also a balanced height for the human body to stretch, only in this way, the human body can quickly enter the dreamland, quickly recover physical fitness, if the pillow is too low, waking up will cause pain in the back of the head, neck soreness and dreams, easy to wake up suddenly;If the pillow is too high, it is easy to compress the cervical spine, causing stiff neck, and the head cannot be rotated when you wake up.
The "three inches" and "four inches" here are the actual height of the pillow when the human body sleeps, not the height of the pillow on the bed, the current pillow is soft and comfortable, and the pillow is immediately sunken, so it looks like it is twenty or thirty centimeters high, but the ancient pillows are mostly jade pillows, porcelain pillows, wooden pillows, etc., and the human pillow will not be dented, so the height of the ancient pillow is between "three inches" and "four inches".
To sum up, longevity is a topic that people will always discuss, and one of the keys to longevity in deep sleep, the pillow as a factor of sleep is also pivotal, as the saying goes, "three inches of longevity, four inches of worry-free", which is the height of the pillow, has your pillow met the requirements?Feel free to leave a message.
