The height of the human body can differ by about 2 cm in the morning and evening.
The height of the person is slightly higher in the morning than in the evening, because the vertebrae of the spine are connected by intervertebral discs, which are elastic and can vary according to the changes in the force under them. When the human body has been working for a day or standing, walking, and running for a long time, the intervertebral discs will be flattened due to compression, and the length of the entire spine will be shortened, and the height will be reduced. However, after bed rest, the disc returns to its original shape without pressure, and the spine returns to its original length, and the height returns to its original height.
Weight also varies, and there are many factors that affect it: eating, excretion, exercise, continuum, etc.

Because people's height will be higher in the morning than at night, this is because the vertebrae of the spine are connected by intervertebral discs, which are rich in elasticity, so its shape can change with the main force it receives, so people's height in a day is different.

Problem description: When I measure my height, there is a difference between morning and night, what is going on?
Analysis: It is due to the fact that the length of the human spine varies throughout the day. The human spine is made up of a number of bone joints.
Connecting these joints are cartilage, which is connective tissue. Cartilage is elastic and deformed when squeezed. When you wake up in the morning and after a night's rest, the cartilage that was squeezed and shortened on the first day will return to its original shape and become taller than the night before.
When you start the day, due to gravity, the spine will gradually be squeezed and stressed due to the weight of the upper body, and the length will become smaller. And man became shorter. Generally speaking, people are the tallest in the morning, followed by noon, and shortest at night.
The height difference between the time periods is about centimeters, so a person will be more than 1 centimeter taller in the morning than in the evening. This also tells us: stretch your waist more when you sleep, and you will grow taller when you walk with your chest up.

Height is based on the morning of the day, height is the vertical distance from the top of the head (v) to the ground, generally in centimeters (cm), and more often use "m" (m) Yuyou. Height is the length of the longitudinal part of the human body, which originates from the longitudinal growth of the human body and is greatly affected by genetic factors.
Girls develop earlier than boys, at the age of 12-13 for a period of rapid growth, to 19-23 years of age to begin to stop growing, while boys develop late, at the age of 15-16 for a period of rapid growth, to 20-25 years old, the long bones of the limbs and vertebrae have completed ossification, the height stops growing. There are many factors that affect height, such as genetics, nutrition, sports, huankai trembling, lifestyle habits, ethnicity, ethnicity, endocrine, sexual maturity (the age of menarche is 5 cm higher than that of 11-year-olds on average), marriage between distant and close relatives, medical progress, and so on.

If you measure your body when you wake up in the morning and measure it again at night before you go to bed, it will surprise you. The length of a person changes throughout the day, and it becomes shorter! In the evening, it tends to be 1-2 cm shorter than in the morning.
If you walk long distances during the day, or do heavy work, then it will even shorten by 4-6 cm. What's going on? Let's look at the structure of the human skeleton.
The bones of the human body are not cast like the skeleton of a machine, otherwise, you would not want to nod your head and turn your neck, dance with your hands, sit and stand at will, and pitch freely. You see, the skull is supported by the vertebrae, and the vertebrae themselves are section by section, and then down, the pelvis bears the bones above, pressing on the thigh bones, and the thigh bones are framed by the calf bones, layer upon layer, like a pagoda. To build a pagoda, you have to glue the bricks with lime, and the bones of people can't be stacked on top of each other like this, and there must be things connected.
Have you ever eaten pork bones? When you gnaw on the bone, if the bone is two parts together, then you can find a milky white thick film called soft bones at the junction of the two parts, which is very tough to chew, a bit like an unsoaked jellyfish skin. It's this thing that binds the bones together.
All higher vertebrates have this cartilaginous layer, and humans are no exception. When we fall asleep, our bones are no longer layered, and the joints are loosened, so the cartilage layer that connects the bones will absorb more body fluid, and it will become thicker and elongated, and when we get up in the morning, it still maintains a loose elastic state, which lifts our body high, so the body is tall in the morning. During the day we are either sitting, standing, or walking, gravity pulls us down from head to toe, so the weight of the head is pressed on the neck, and the weight of the head and neck is pressed on the vertebrae, and the weight of various bones is pressed down in turn, and the cartilage layer between each bone node is pressed by gravity, and it has to contract.
In this way, the body that was originally raised by it was shortened.

You have, when people are tired, the structure of the human body is in a tight state, the gap between the tissues is shortened, and when there is no pressure, the tissues are not in a tight state, that is to say, after a night's rest, the body is more relaxed, and the gap between the tissues is looser than before going to bed at night, and there will be a less obvious increase.

Yes. It's just that we don't feel it! Sometimes one day we suddenly feel like we've grown taller! Haha, right!

If there is a change, the height at night will be nearly 1cm shorter than in the morning.

It is true that people's body temperature will vary from time to day of day, and the main reason for this is the metabolic status and the environment in which they are located, and the temperature is also related to certain factors. The temperature will be different in different seasons throughout the year, and the body temperature will be different in different seasons, so the environment in which a person is located also affects the change of a person's body temperature. For example, in a hot temperature, a person's body temperature may rise slightly, and in a cooler area, a person's body temperature may drop, but a person's normal body temperature is mostly maintained between 36 and 37 degrees, and the temperature change will not be particularly large. >>>More

The thirtieth month of the lunar month celebrates the New Year. During the day of the Chinese New Year's Eve, the ancestors should be graved, fish, meat and wine, paper money, incense, etc., and then firecrackers should be set off next to the ancestral grave, indicating that the ancestors should be awakened with firecrackers, so that the ancestors can eat something and collect some money. Then he prostrates, and the way of prostrating is the same as in the ancestral hall. >>>More
