However, these unnoticed behaviors have some special fitness effects. One of the tips: yawning is a physiological need of the body. It is a signal of nervous fatigue, indicating that excitement is about to reach or has reached the highest point, reminding people that they should rest at this time. In addition, yawning helps to relax eye muscles, promote eye blood circulation, and make eyes feel brighter and more comfortable. Scientists from the American Health Association also suggested that people who stare at computers for a long time might as well yawn when they are tired to relieve eye fatigue. The second measure: stretching "stretching can relieve fatigue." Stretching the neck and lifting the arm is a way of stretching the waist, exercising muscles and relaxing the spine. In just a few seconds, a large amount of congestion can be washed back to the heart, increasing blood circulation and improving blood circulation. In addition, stretching can also dredge the blood vessels in the neck, so that it can smoothly deliver blood to the brain, so that the brain can get enough nutrition, thus relieving fatigue and invigorating the spirit. Moreover, it can make the muscles of the whole body, especially the waist muscles, exercise in rhythmic stretching, gradually develop and strengthen, prevent the strain of the waist muscles, correct the excessive forward curvature of the spine in time, and maintain a healthy figure. The third measure: chest expansion People may wish to do a few chest expansion actions after work and when they are tired. This can not only exercise chest muscles, but also increase vital capacity, improve respiratory function and improve the quality of work and life. At the same time, chest enlargement can exercise the pectoral muscles, stretch and stimulate the thymus, and promote it to secrete more immune substances, thus improving its ability to resist diseases and cancer. The fourth measure: deep breathing can increase the ventilation volume and ventilation volume of the lungs, improve the oxygen saturation, and promote the full play of the functions of various organs and systems in the whole body. In addition, it can also promote blood circulation in the lungs, which is conducive to the smooth discharge of residual gases and other metabolites in the lungs. In addition, deep breathing can also stimulate the alveolar dilator, causing parasympathetic nerve excitement, thus relaxing the body and relieving tension. "Although many small moves are good for your health, some small moves in your life, such as picking your nose and ears, are harmful to your health." Experts also reminded that. Some people like to pick their noses, which is not only unsightly, but also harmful to health. There are a lot of dirt and germs hidden in the nails, which are hard and sharp. When picking your nose, a little carelessness will lead to nosebleed, bring bacteria into the wound, cause nasal vestibulitis, or red lumps or suppurations at the tip of your nose and nasal sac. It is also harmful to the human body to use hairpins, matchsticks, ear scoops and other tools to pull out the ears. Improper ear pulling can easily cause damage to the external auditory canal, and even lead to swelling, inflammation and ulceration of the external auditory canal, resulting in unbearable earache and affecting mouth opening and chewing. Some people like to pick their teeth after meals, which is also a very bad habit. Tooth picking can damage teeth and gums, leading to gingival atrophy, root exposure, tooth widening, and food residues are easier to stuff in. After a long time, teeth will be sensitive to food and cause toothache.
