Health beauty: the beauty of human body is because it conforms to the law of beauty. Among them, health is the primary condition for human beauty. From the biomedical point of view, human organs are well developed, functioning normally, physically strong and energetic, which means health. Another important part of health is that all systems and organs of the human body function normally. This is also a necessary condition for human beauty. If you have a disease in your waist, it is difficult to walk, and your posture is stiff, you will lose your beauty. Another example is facial paralysis. Although it is well developed, nerve conduction is blocked, muscle activity cannot be controlled, and symptoms such as hanging eyes and crooked mouth appear, which destroys the symmetrical and harmonious relationship of the face and disappears the aesthetic feeling. All these show that only when the organs function normally can the beauty of the human body be displayed.
Proportional symmetry and overall harmony are essential conditions for human beauty.
Physical beauty: beauty of proportion, beauty of lines, beauty of colors, beauty of sounds,
Beauty of proportion: the proportion of human body is the comparison of various organs and parts of human body. For example, the proportional relationship between eyes and face, the proportional relationship between trunk and limbs, and so on. Regarding this proportional relationship of the human body, China has long had the "three stops and five eyes" of the human face, and made clear the vertical and horizontal proportional relationship of the frontal view of the human face. "Three stops" refers to the horizontal division of the forehead and face into three equal parts, that is, the hairline stops from the eyebrow line, the eyebrow line stops from the bottom of the nose, and the bottom of the nose stops from the bottom of the chin. "Five eyes" refers to vertically dividing the front face into five equal parts, with the length of one eye as an equal part, that is, the distance between two eyes is the distance of one eye, the distance from the vertical line of the outer corner of the eye to the vertical line of the outer ear hole is the distance of one eye, and the whole front face is vertically divided into five eyes. According to the proportion of "three stops and five eyes", the proportion of faces drawn is harmonious. The golden ratio of western facial golden section method is 1.6 18. The head-to-body ratio is the proportional relationship between head and body length. There is a saying about the head-to-body ratio in Chinese painting, that is, the person standing is seven heads long, the person sitting in the chair is five heads high from head to head, and the person sitting cross-legged is three heads high. For example, if a person's height is 1.6 18, then his lower body is 1 meter. The upper body is 0.6 18. Height-to-weight ratio: the calculation formula of standard weight is: male standard weight (kg) = 50+[ height (cm)- 150] × 0.75+ (age -2 1) ÷ 5 female standard weight (kg)= 50.
Beauty of overall harmony: overall harmony is also an important part of human beauty. The overall harmony of the human body comes from the formal beauty factors such as balance, symmetry and coordination. The overall beauty of the human body is composed of many parts, which are interrelated and mutually restricted. Small face and big nose are not harmonious, and oriental flat face with European double eyelids looks awkward. Sandy Lam's eyes are small, but her face makes people feel harmonious and beautiful as a whole. Some people's facial features don't look very good one by one, but when combined, they give people a sense of beauty. Therefore, overall harmony is an indispensable element of human beauty.
Beauty of lines: The beauty of human body lines includes human body contour lines and human body dynamic lines. Human body lines are composed of straight lines and curves, with straight lines as the central axis, and have various relationships with curves on the basis of stability. The straight line tends to be calm, just like lyric in indifference; The curve is biased towards enthusiasm and is the lover of the sun. Straight lines tend to be masculine, which is a man's boldness of vision; Curves represent femininity, which is the unique beauty of women. Since ancient times, people's appreciation of men has never changed. Tall, rough and crazy, the proportion of lines with wide top and narrow bottom indicates the symbol of strength, which is more prominent in the west. No matter from the description of male gods in Greek mythology, or the Colosseum in Rome and the Vikings, they all appear in this image.
Color beauty: the color beauty of human body includes the inherent color of human body and the decorative color of human body.
Beauty of sound: The beauty of sound is one of the elements of human beauty. Sound is produced by the vibration of an object, and the vibration of the object will produce a vibration wave, which is sound wave. The frequency of sound waves is 20-20000 Hz. Beyond this range, we can't hear it. Hearing no sound doesn't mean that there is no vibration, but people's ears can't detect this vibration wave.
Physical beauty
The beauty of five senses is the main content of human beauty. Appearance beauty is not only the expression of life activities, but also the externalized form of internal activities, which embodies the personality of human beauty and is the main part of evaluating human beauty.
