Too much or too little sleep may make your body age faster

A study using organ-specific biological clocks found that people reporting fewer than six or more than eight hours of sleep tended to show faster aging across the body. The findings reveal an association rather than causation and suggest that short and long sleep may be connected to late-life depression through different biological pathways.

一项使用器官特异性生物时钟的研究发现，每晚自述睡眠少于6小时或多于8小时的人，往往会出现更快的全身衰老。研究结果显示的是相关性而非因果关系，并表明睡眠过短和过长可能通过不同的生物学途径与晚年抑郁相关。
