The golden section of human body is the ratio of the height of navel, lower half and upper half, the length of calf and thigh, the ratio of forearm and upper arm, and the triangle formed by shoulder and genitals, which all conform to the golden section law, that is, the approximate value of 1: 0.6 18.

For human face, when the aspect ratio of face is 0.6 18, it is the most perfect face shape; When the ratio of upper body length to lower body length is 0.6 18, it is the most harmonious figure. The ratio of our teeth, ears, width and length is also about 0.6 18. In the human body, the digestive tract is 9 meters long, multiplied by 0.6 18 is exactly 5.5 meters, which is the length of the small intestine responsible for digestion and absorption.

Jefferson, a dentist in Monterey, New Jersey, said: This ratio is not only about aesthetics, but also about health. For example, people with long faces are generally prone to breathing problems, because their sinuses are narrow and they often need to breathe through their mouths, which may lead to snoring or even insomnia, and may also lead to tooth deformity.

If the face is too short, the mandibular joint will easily press the blood vessels and block some blood from flowing into the brain, which will lead to headache, which will further aggravate the muscle tension around the mandibular joint and lead to molars.

Extended data:

The human body temperature is also directly related to the golden ratio. The freezing point of water is 0℃ and the boiling point is 100℃. The normal body temperature is around 37℃, just around the negative golden section of 0.382. The body temperature of all other creatures also fluctuates up and down at this value.

Based on the normal body temperature of 37℃, it can be concluded that the human body feels most comfortable at 22-24℃, because the product of 37℃ and 0.6 18 is 23℃, and at this ambient temperature, the metabolism, circadian rhythm and physiological function of the body are in the best state.

In this regard, Hong Zhaoguang, the chief health education expert of the Health Planning Commission, said that it is true that 23℃ is the most comfortable, so it won't feel hot at work and cold when sleeping. ?
