冬天,人们的被子加厚,有人甚至盖上两三层的大厚被,这种做法不仅影响睡眠,更会对呼吸道造成伤害。冬天开窗少,氧气含量相对小,厚棉被压在胸上,会造成轻微的缺氧。厚棉被灰尘多,几层被的灰尘吸入呼吸道,对呼吸道黏膜造成一定的影响,尤其是气管炎和肺气肿患者,这种铺盖方式容易引起疾病复发。 In winter, people’s quilts are thickened. Some people even cover two or three layers of thick and thick beakers, which not only affects sleep, but also harms the respiratory tract. Fewer windows in winter, the oxygen content is relatively small, thick cotton is pressed on the chest, can cause slight hypoxia. Thick cotton is dusty, several layers of dust inhaled into the respiratory tract, respiratory mucosa have some impact, especially in patients with tracheitis and emphysema, this method of bedding easily lead to disease recurrence.
