课程简介和演讲视频

课程简介
本套课程讲解了睡眠对健康的多重影响。睡眠不足会改变身体的内分泌系统，打破激素的平衡，扰乱大脑对食物的选择和摄取从而引发肥胖，严重影响胰岛素的平衡进而引发糖尿病。不同年龄段的人群有不同的睡眠需求，一般而言，年轻人的睡眠需求高于老年人，但所有成年人都应保证每天8小时的睡眠时间。老年人的睡眠时间减少并不是生理变化的自然结果，而是其他疾病造成的影响，衰老本身并不会降低睡眠需求。常见的睡眠障碍包括失眠、睡眠呼吸障碍、四肢不宁综合症、快速眼动期行为失调，患者需要就具体的睡眠障碍咨询专业的睡眠医生，确诊后有针对性的改善睡眠，进而提高整体的健康状况。不同的睡眠障碍有不同的治疗方式，但认知行为疗法是所有治疗方法的首选，其次是器械治疗、药物治疗以及外科手术治疗。患者应养成良好的睡眠习惯，培养“睡眠卫生习惯”，改善睡眠质量，尽量避免擅自用药和药物滥用。
