Breathing skills
According to a recent special survey by American researchers, at least half of the urban population failed to breathe, showing shortness of breath, and they often exhaled in a hurry before fresh air reached the lower end of their lungs. At the same time, people who are used to this kind of "shortness of breath" are mostly "white-collar workers" who work for a long time. When they are in danger, their chests are compressed, and their breathing often depends only on the upper lungs, which leads to the low fluidity of the diaphragm.
The key to correct breathing is to be calm and let the inhaled oxygen penetrate into every corner of the lungs. Exhale should take twice as long as inhale. Try to breathe through your nose, not your mouth.
The researchers pointed out that once the wrong way of breathing is changed, many common diseases, such as asthma, bronchitis, hypertension, heart disease, headache and so on. There will be a certain degree of relief, even for some intractable diseases, such as menstrual disorders, various allergic reactions and so on. , will also achieve a certain curative effect.
Sit down and study.
As the saying goes, "stand and stand, sit and sit." The correct sitting posture is: sitting on a wooden chair with a backrest, with the hips and knees bent 90 degrees, and the lumbar spine and backrest as close as possible, leaving no gap. Generally sit 1~2 hours, stand up and exercise your waist.
Adhering to the correct sitting posture is very important for the health of the spine, especially the lumbar spine. There is a simple reason. Among the three postures of standing, sitting and lying, sitting posture is the most unfavorable to waist health. Wrong sitting posture and overwork will greatly increase the degree and time of bending. According to statistics, the maximum number of waist bends in a day can reach 3000~5000 times. This kind of excessive and repeated flexion is the most common cause of lumbar diseases, and preventive measures must be taken.
Talk about science at dinner.
Eating seems simple, but in fact it contains science. First, try to chew slowly. Chew a bite of food at least 20~30 times. Taking cancer prevention as an example, experts have observed through experiments that chewing for 30 seconds can reduce the toxicity of carcinogens. If a bite of food is chewed for 30 times and then swallowed, the anticancer effect of saliva can be fully exerted. Therefore, a bite of food should be chewed at least 20 times, and it is ideal if it can reach 30 times.
Secondly, chewing should be bilateral, not unilateral. Unilateral chewing can lead to muscle tension or shoulder pain on one side of the face, or loose teeth on one side, leading to cheek asymmetry and even hearing loss. A research team from Tokyo Dental University surveyed more than 200 people and found that continuous unilateral chewing would reduce the hearing of the other ear. Chewing only the front teeth will reduce the hearing of treble; Chewing only by grinding teeth will reduce the hearing of bass.
