Chalk dust has made the teacher suffer enough. In addition to the throat, vocal cords are also one of the "fragile" parts of the teacher. Talking too much, drinking too little and inhaling chalk dust are the main reasons why teachers often have pharyngitis. Teachers should pay attention to the scientific use of sound, correct the way of speaking and change chest breathing into abdominal breathing. Pay attention to the volume when giving lectures, and don't speak too loudly or too urgently; Let the vocal cords have a rest during recess; Commonly used warm water and mint buccal tablets to moisten the throat; Eat less irritating foods such as peppers and high-sugar foods such as chocolate, and eat more foods that clear lung and nourish yin, resolve phlegm and dissipate stagnation.
2. Varicose veins
Teachers need to stand for a long time to teach, and the blood column in the vein of lower limbs forms the pressure in the vein, which makes the venous blood not easy to flow back to the heart, but back to the feet, leading to varicose veins of lower limbs. When giving lectures, teachers should alternately transfer their body weight from one foot to the other, always keep one foot at rest and walk slowly; We should make full use of the rest time to exercise our legs and promote blood circulation. Jogging, joint flexion and extension activities and leg massage can all prevent varicose veins.
3. Cervical and lumbar diseases
Teachers work at their desks for a long time, paying high attention and preparing lessons for a long time, which is easy to cause neck muscle tension. After a long time, it will cause chronic damage to the neck muscles and ligaments, and in severe cases it will develop into cervical spondylosis. The waist pressure is several times that of standing, and it is easy to cause lumbar disc herniation after a long time. Therefore, we should try our best to maintain a natural sitting posture, adjust the posture and length of time at work, exercise moderately, have a full rest, and do some exercises such as chest expansion, waist twisting and limb movement.
(1) Strengthening the exercise of the neck and shoulder muscles, and doing the flexion, extension and rotation of the head and upper limbs at work or after work can not only relieve fatigue, but also develop muscles and enhance toughness, thus contributing to the stability of the cervical spine and enhancing the adaptability of the neck and shoulder to sudden changes in the neck.
(2) Avoid the bad habit of sleeping on a high pillow. The high pillow bends the head forward, which increases the stress of the lower cervical spine and may accelerate the degeneration of the cervical spine.
(3) Pay attention to keep the neck and shoulders warm, avoid heavy objects on the head and neck, avoid excessive fatigue, and don't doze off while riding.
(4) Early and thorough treatment of soft tissue strain of neck, shoulder and back to prevent it from developing into cervical spondylosis.
(5) When working or walking, prevent flash and contusion.
(6) Long-term desk workers should change their head position regularly and do neck and shoulder muscle exercises on time.
(7) Pay attention to correct the posture of head, neck, shoulders and back, and don't shrug, talk, or read positively. Keep your spine upright.
(8) Chinese medicine believes that walnut, Cornus officinalis, Radix Rehmanniae and black sesame have the function of tonifying kidney and promoting marrow. If eaten in a reasonable amount, it can strengthen bones and muscles and delay the degeneration of kidneys and joints.
4. mental illness
In people's minds, teachers are like the perfect embodiment of wisdom and morality. Praise for teachers' profession reflects people's reverence for teachers' profession; On the other hand, it also exerts great pressure on the teachers. If this kind of pressure accumulates for a long time, it will easily lead to mental illness. Psychologists believe that psychological exhaustion has become an occupational disease in modern society, and teachers are one of the high-risk groups of this psychological disease. Psychological exhaustion will make them often have negative emotions such as fatigue, irritability, irritability, tension, depression and paranoia. The decrease of sense of accomplishment is accompanied by psychological exhaustion, which will make them depressed, stop pursuing achievements and progress at work and delay their own development. Mental health is also the quality requirement of teachers. Once a teacher bears a heavy psychological burden, it is difficult to meet the needs of teaching.
