嗜睡症;过度嗜睡:一种以白天过度困倦、睡眠时间异常延长或即使睡了很久仍感到疲惫为特点的睡眠障碍。(也可泛指“过度睡眠”的状态;医学语境更常指疾病。)
/ˌhaɪpərˈsɑːmniə/
I was diagnosed with hypersomnia last year.
我去年被诊断为嗜睡症。
Even after ten hours of sleep, his hypersomnia made it hard for him to stay alert during meetings, affecting his work performance.
即使睡了十个小时,他的嗜睡症仍让他在会议中很难保持清醒,影响了工作表现。
来自希腊语构词:**hyper-**(“过度、超过正常”)+ **somn-**(与“睡眠”相关,见于 somnolent 等词)+ -ia(表示“状态/疾病”的后缀)。合起来就是“过度睡眠/嗜睡的状态”。
