睡眠过少或过多可能加速身体衰老

哥伦比亚大学研究团队发表的一项研究表明，睡眠时间过短或过长都与身体多个器官的加速衰老密切相关1。该研究分析了英国生物样本库约50万名参与者的数据，运用23个生物衰老时钟对17个器官系统进行评估，发现最优睡眠时长为每天6.4到7.8小时1。

研究显示，睡眠不足6小时与抑郁症、焦虑症、肥胖、2型糖尿病、高血压、心脏病和心律不齐等多种疾病相关1。同时，短睡眠和长睡眠（超过8小时）都与慢性阻塞性肺病、哮喘、胃炎和胃食管反流病等疾病存在关联1。哥伦比亚大学瓦格洛斯医学与外科医学院放射学助教授温俊豪（Junhao Wen）参与了这项研究1。该成果已于2026年8月24日发表在《自然》期刊上1。

Researchers at Columbia University have found that both insufficient and excessive sleep are associated with accelerated aging across multiple organ systems. The study analyzed 23 biological aging clocks encompassing 17 organ systems in approximately 500,000 participants from the UK Biobank, revealing that the lowest aging rates occurred in individuals sleeping between 6.4 and 7.8 hours daily 1.

Short sleep duration—defined as less than six hours per night—was linked to depression, anxiety, obesity, type 2 diabetes, hypertension, heart disease, and cardiac arrhythmias 1. Both insufficient and excessive sleep, exceeding eight hours nightly, were associated with chronic obstructive pulmonary disease, asthma, gastritis, and gastroesophageal reflux disease 1. The research, led by Junhao Wen, an assistant professor of radiology at Columbia University's Vagelos College of Physicians and Surgeons, was published in Nature on August 24, 2026 1.
