It is generally believed that people shine their teeth and wash their faces every day, so it is not a big deal! However, perhaps you do not know, it is this little thing, if not handled properly. It can also lead to serious consequences. We often encounter such patients in the clinic, saying that he slept well last night, who knows that in the morning, after shining teeth, washing the face, the waist can not straighten up, and sometimes there will be lumbar pain to one or both sides of the lower limbs radiation phenomenon. It turns out that in the early morning, the body after a night’s sleep, back muscles, fascia, joints, joint capsule and ligaments and other tissues will be in a stiff, stiff state and difficult to move flexibly. At this time, if the waist from lying down and relaxed state suddenly changed to half sitting, half standing, half squatting posture, will be on the lumbar intervertebral disc, lumbosacral joints, ligaments and joint capsule to produce greater shear and pressure, especially the usual lumbar discomfort or back pain, the impact is greater, a little inattention, and can even become the cause of lumbar disc herniation or attack. And most people get up, generally go to the washroom first po” or “wash”, wash often bend down and waist, half standing half squatting, for about half an hour, which is the cause of lumbago after a sudden change in lumbar posture. In order to avoid triggering or aggravating lumbago during the washing action such as shabu-shabu and face washing, besides moving the lumbosacral region slightly when getting up, so that the lumbar region has a period of adaptation from a relatively static state to an active state, the most important thing is to pay attention to the posture when shabu-shabu and face washing. First of all, you should slightly bend your knees and squat, then bend forward and weigh the discomfort of your waist, and when you feel that your waist can bear it, then start to shampoo your teeth and wash your face. If you feel lumbar and sacral pain during washing, you should immediately rest for a while with straight legs and then continue washing. Taking the premise that the lumbosacral pain does not occur, flexible control and improvisation can largely reduce the shearing force of the lumbosacral joints and the pressure on the lumbar intervertebral discs, so as to avoid the occurrence of lumbago or the recurrence of lumbar disease. Secondly, the washbasin should not be too low. When renovating rooms and bathrooms, the average height of family members should be designed according to the corresponding height of the washbasin. Families with conditions, such as two bathrooms, or a bathroom area is large, you can set two different heights of the washbasin to adapt to the different heights of family members wash required. The general principle is that the washbasin rather high, not too low. Because the washbasin is too low will make the lumbar vertebrae bend forward excessively, resulting in excessive shear and load on the lumbosacral area, easy to trigger or aggravate lumbago. Experts pointed out that after waking up in the morning, do not rush to do things, should be the first in the indoor activities of the waist. You can slowly turn two circles, walk while throwing arms, and then bend and stretch and turn a few waist; lower limbs squat, stand up several times; and then double fist or hands pound back, knead waist, pat legs dozens of times. This can improve the blood circulation and limb tension of the whole body in the upright state, and adapt to the upcoming preparations such as washing and toileting before going to work. Some people like to go outdoors first after waking up to move their waist and limbs, and then wash, of course, is also very good, can play the role of “warm-up”. In short, wash up to be smooth, waist posture as a guarantee; half squat chest leaning forward, shabu teeth good mood. Raise the washbasin, wash the waist does not hurt; warm up in advance, the waist more stable.
