Sitting on a chair and computer posture

Sitting on a chair
Most people who work long time sitting on a chair feel stiff or pain in the shoulders and(or) waist.

Seeing the general posture, People let the back of a chair be pushed out(Angle of 100 ~ 130 degree), and let their waist bone be forward curved. These make the shape of the spine be the character of "C". With this posture, People feel comfortable at first, but time goes on, they feel Stiff and pain. For having correct posture, please buy a subsidiary back of chair at auto tackle store. Let's see the way to make a correct posture.

(1) Let the back of a chair be straight(90 degree). (Incorrect posture : Let the back of a chair be 100 ~ 130 degree)

(2) Sit on a chair deeply for the hips to stick to the back of a chair.(Incorrect posture : Sit on a chair for the hips to be far from the back of a chair.)

(3) Regulate the up and down position of a subsidiary back of chair for both the waist and the lower curved region of a subsidiary back of chair to be knitted each other. .(Incorrect posture : Don't use a subsidiary back of chair)

(4) Let the distance between two knees be the one between two shoulders, and let the distance between two soles of the foot be the one between two shoulders too. In this posture, the whole soles of the foot contact to the floor.

(5) Confirm the angle between the knee and the calf of the leg to be an angle of 100 ~110 degree. if not, regulate the level of seat.

(6) Confirm both foots to be put forward with a same distance.

If people make upper mentioned posture completely, they will crack farts and get hot in body. Someone whose spine and leg were not located correctly can feel pain. If this pain is unbearable, let's go slowly. It's better to make this posture step by step.

When you make upper mentioned posture long time, if you feel pain in your back, please put both foots more forward, if you feel pain in your waist, please put both foots more backward. This regulations make the stress not to be concentrated at any point.

To sit on a chair deeply for the hips to stick to the back of a chair makes the waist be backward curved. 100 ~110 degree of angle between the knee and the calf of the leg and for the whole soles of the foot to contact to the floor makes the back not tilt forward.

Also, there is one ting no less important than the upper mentioned posture. Position the objects(TV, monitor, book and so on) at an angle of 10 ~30degree from front side, and select my seat so that the angle of my view to see a speaker is more than 10 degree. If you have a difficulty in maintaining upward view continuously, You may have caved in ribs and forward tilted back bone and neck bone.

Computer posture
Sitting in accordance with upper mentioned posture, position the monitor so that the top level of head is equal to the bottom level of the monitor. But if you raise a monitor suddenly, it can give a excessive stress to the spine. So, divide it into 3 ~ 4 steps and raise the every level after maintaining 1 ~ 2 months

The locations of keyboard and mouse are also important to get a correct posture. Generally people put their keyboard at the 30 ~50cm front of their chest and mouse at the 30 ~50cm diagonal front of their chest. But for the back to be straight or backward curved, the mouse should be moved to the flank as more as possible, and finally it is better for the mouse to be put on the chest extension line. It will be uncomfortable and awkward at first, but if practiced, you will not feel stiff or pain in the shoulders and(or) waist and you will not feel thick in your eyes, even though you work long time on your chair.

Technique of sleeping

There are many suffering people who are difficult to get to sleep(Insomniacs) or to wake up in the morning(Heavy sleepers). The reasons why People have a difficulty in getting to sleep is mainly disorder of immunity, excessive stress and so on. Temporary stress can be disregarded, but frequent stress should not be disregarded. Disorder of immunity generally comes from twisted or curved spine.

Slight sleepless can be easily overcome by relieving the twisted or curved spine with relaxing in a sauna sufficiently and by the stretching of making backward curved spine during around 10 minutes. Insomniacs need correction of spine. Heavy sleeping comes from that the stress is not sufficiently gotten rid of during sleeping. Getting rid of stress fast and efficiently, keep in mind following.

Sleeping is autonomous body activity which gets rid of daytime stress and vitalize itself by feeding fresh blood containing oxygen(absorbed by breathing during sleeping) and nutritive elements(absorbed by foods). But some factors are required for this activity to be done well. If these necessary conditions are satisfied, delightful morning welcome you.

Pillow
Pillow should be positioned not at the back of head but at the back of neck, and the suitable diameter of pillow for adult is 8cm ~ 12cm. You can make it easily to roll bath towels. I named it the neck pillow. Why this neck pillow is better ?

First, the lower your head, the more you can do abdominal breathings rather than chest breathings. Lying on your back and comparing breathing times(during 1 minute) between using very high pillow and using the neck pillow. Using very high pillow, you will get more breathing times, because you breathe with up and down of chest(short breathing). But using the neck pillow, you will get less breathing times, because you breathe with up and down of the abdomen(long breathing). Abdominal breathing is very important factor to have the best vitality.

Second, the very high pillow makes neck bone tilt forward, accordingly the forward tilted neck bone makes the waist bone be straight. But the neck pillow makes neck bone be straight, accordingly the straight neck bone helps the waist bone to be backward curved. Living with forward tilted waist and back in the daytime activity for several years or for several decades, this wrong pose has been fixed. The very high pillow, naturally helps to sustain this wrong pose, accordingly people can feel very comfortable, so people seek higher pillow than before again and again.

Living during daytime activity, they don't sense the pains caused by wrong pose, because they focus on their works, or don't know the way to get rid of the sensed pains. So they mostly leave behind the pains. But when they lies on their bed, as their all activities were stopped, the pains made by daytime activity are sensed distinctively. So they want to escape from this pains, accordingly the high pillow satisfies this desire.

Pose
Pose lying on one's back is the best one, as this pose makes the spine be natural line and press the spine symmetrically. It's better to stretch one's legs straightly. If you feel uncomfortable with this pose, it can be an evidence that your spine is twisted or curved. On one side, sometimes you'd better to change into the pose which the body want.

Food
It is better not to have meals 2 ~ 4 hours before sleeping, because you have to digest foods which you eat before sleeping, accordingly you can't completely relax yourself. Drinking water or beverage, 0.5 ~ 2.5 hours of urinating time is necessary in proportion to the drinking quantity.

Technique of walking

For good walking, prepare a pair of running shoes of which the bottom piece has entirely no slope. If there were commercialized products, it is better to put on the shoes of which the front of bottom piece is a little bit higher than the back. This front high shoe helps people to get a healthy pose naturally without any effort. It is easy to know that hilled shoes make the center of body go more front and down side. Riding on an entrance of a going up escalator with a pose of forward curved waist and straight back, strained region goes up more and more from hips to the pit of the stomach.

Let's look around the most important 2 factors in walking.

First, after making the knee and the calf of backward going leg entirely straight, let this leg go forward and the walking speed should be a little bit slow. This way of walking make most of muscles be used and blood be circulated every nook and corner, helps the waist to be forward curved and the back to be straight or forward curved, and People, who used to get tired easily eventhough they walked a little bit, not get tired easily.

Second, walk with putting a higher view point than front side. There are many people who have a difficulty in putting a view point even to the front side. The reason why people who have forward tilted back can’t make their back be straight easily is that they have not only forward tilted back but also backward curved shoulder bones and ribs. “Homework to return to origin” make the neck bone, the back bone, the shoulder bones and the ribs come back to the birth conditions. Getting back to the birth conditions, people can put a view point with an angle of around 20 ~ 30 degree.

Statistically, people who live on the hill or in 3~4 floor apartment without elevator go hospitals rarely than normal people, and the foot diseases of Africans who live without shoes are only approx. 3% of the total orthopedic diseases, but approx. 60% in westernized societies. If possible, restrain using elevators and escalators and use upstairs and uphill roads delightfully.

keeping upper 2 factors, people are able to have feelings of strain in the pit of the stomach, and have feelings of supple movements in the knees, hips, waist and back. Walking unintentionally, people are able to know whether they are getting a good pose or not, by confirming their pit of the stomach being strained.

Homework to return to origin

Necks of most modern people tilt forward slightly or deeply. Precisely speaking, the reason of forward curved waist and back also originated from the forward tilted neck.

The neck bone, back bone and waist bone are not independent each others. People can't make back bone be straight or backward curved and waist bone be backward curved on condition that his neck bone tilts forward. If neck tilts backward, back bone is automatically straight or backward curved and waist bone is also automatically backward curved. In conclusion, angle of head is the core of making right pose of spine.

Searching the 2 dimensional mass center of head viewing the front side, it comes that the mass center of head locates forward approximately at an angle of 16 degree from the neck bone line(See bellow figure). The period of making a living(mainly hunting and picking fruits) with backward curved spine is approx. 2 million years(from approx. around 2 milion years to B.C. around 3,000 year). But the period of making a living(mainly farming and laboring) with forward curved spine is approx. 5,000 years(from B.C. around 3,000 year to present). The period ratio is 400 : 1. Human being is mostly making a living with forward curved spine only during around 5,000 years, but I think that the remarkable evolution is not fulfilled during just around 5,000 years.

So, if possible, position the looking objects higher than the front side. but it is impossible to look every things with upward view all day long. So, let's do the "homework to return to origin" everyday.

How should it be done ?

First, after lying on your back on your bed, put together the connecting line of your two feats and end line of bed. then hang down your head and completely loosen your muscles. It is better to use very hard bed than soft bed. If you don't have hard bed, it is also good to lay wood plate on the bed. Wood table is also possible.

Second, continue the upper mentioned pose during approximately 30 minutes. it's better to relax completely without thinking. People, who is going to start this homework for the first time, should do the homework during approximately 5 minutes in the early stage. Time goes on, increase the time.

Third, it is increase the effect of the homework to be sunk in meditation during the homework. The meditation is, shortly speaking, making your brain in rest.

Fourth, from around 2 hours later after having a meal, drink 3 ~ 5 cups of water until you have feeling that the drunken water is urinated immediately. It is easy to make nothing of water, but it is very important. If you don't have sufficient water in your body, you can get a problem in your metabolism. If possible, drink natural water. distilled water is better.

Generally, the reason why people who have forward curved back can’t make their back be straight easily is that they have not only forward curved back but also forward curved shoulder bones and ribs. “Homework to return to origin” make the neck bone, the back bone, the shoulder bones and the ribs come back to the birth conditions.

If you make homework steadily, thick eyes, fine wrinkles of face, nose diseases, ringing in the ears, pain of neck, fine wrinkles of neck, pimple and so on are going to be solved, if continue to do homework more, people can be liberated from the function decline related diseases like hypertension, heart disease, diabetes, obesity, inveterate dyspepsia and so on.
