1.衣领松。人的颈部有影响血压变化的压力感受器官,位于人颈部两侧甲状腺上缘血管搏动处,黄豆大小、呈卵圆状的组织,医学上叫“颈动脉窦”。衣领太小或领带扎得过紧,可能会压迫到这个敏感的部位。因为颈动脉窦接近体表,所以对外来的刺激相当敏感。当它突然受到机械性压迫或牵拉时,便会产生心血管反射,使血压下降、心跳减慢,导致脑部血液的暂时减少或中断而发生晕厥。故高血压病人衣领要宽松,不要扣得太紧,最好不结领带。2.裤带松。冬季衣服穿得较多,裤带容易系得紧,但太紧会导致腹腔压力
Loose collar Human neck pressure changes affect the pressure receptors, located in the upper neck of the human neck on both sides of the thoracic artery beat, soy size, oval-shaped tissue, medically called “carotid sinus.” The collar is too small or tie too tight, may oppress to this sensitive part. Because the carotid sinus is close to the body surface, it is quite sensitive to external stimuli. When it suddenly under mechanical compression or traction, it will produce cardiovascular reflex, so that blood pressure, heart rate slowed, resulting in a temporary reduction or interruption of blood in the brain and syncope. Therefore, the collar to patients with loose blood pressure, do not buckle too tight, it is best not to tie. 2. belt loose. Winter clothes to wear more, easy to fasten the belt tight, but too tight can cause abdominal pressure
