男子平均睡眠7小时，却3年2次脑梗！医生紧急提醒……
双语君约 4 分钟据了解，刘先生的作息很不规律：周一到周四，凌晨2点睡、早上7点起；周五经常加班到凌晨3点。但他每到周末就会疯狂补觉，一觉睡到中午12点，下午还要睡午觉。
A 45‑year‑old man in China suffered two strokes within three years despite averaging seven hours of sleep per day. Doctors say the key trigger was a disrupted circadian rhythm — caused by chronic weekday sleep deprivation followed by excessive weekend lie‑ins.
According to a report, the patient, surnamed Liu, was admitted to the hospital following his second stroke. From Monday to Thursday, he went to bed at 2 am and woke at 7 am, often worked until 3 am on Fridays, and then "crashed" on weekends by sleeping until noon and taking afternoon naps.
不少网友看过后有疑问：明明睡够了7小时，为什么会反复脑梗？
浙江省中西医结合医院脑病中心神经内科主任医师赵晶医生指出问题根源：“睡眠从来不是简单的时长加减法，周末强行补觉，看似补齐了睡眠时长，却补不回被破坏的‘生物钟’。生物钟不仅管你困不困，还调控着血压、血糖、激素分泌、免疫功能的节律。”长期混乱的作息，正是导致他反复脑梗的重要诱因。
医生提醒，这不是在补觉养生，是在拿血管开玩笑。
Zhao Jing, chief neurologist at the hospital's brain disease center, explained that sleep is not a simple arithmetic of hours. "Forced weekend catch‑up may add up the total hours, but it cannot restore the broken biological clock," Zhao said. "That clock regulates not just sleepiness, but also blood pressure, blood sugar, hormone secretion, and immune function."
Chronic disruption of this rhythm was a major contributing factor to his recurrent strokes. Physicians warn that such habits are not health‑restoring but essentially "gambling with the blood vessels".
研究发现：周末过度补觉危害大
周末适当补觉能缓解疲劳，帮助身体恢复精力。但周末补觉的时间并非越长越好。据生命时报，美国《预防医学》杂志上的一项研究显示，补觉时间超过3小时，全身炎症风险会明显上升。
Research supports the concern. A study in the journal Preventive Medicine found that extending weekend sleep by more than three hours significantly raises the risk of systemic inflammation, as reported.
清华大学北京清华长庚医院睡眠医学中心主任医师于逢春表示，临床上观察到，长期睡眠少于6小时或超过9小时的人群，代谢综合征、糖尿病及死亡风险通常更高。
科学补觉，牢记这4点
上海中医药大学附属龙华医院脑病科主任医师袁灿兴表示，偶尔熬夜后，合理补觉可以缓解困倦，但要遵循以下原则——
For occasional sleep deficits, there are four principles for safe sleep recovery:
① 午睡别超30分钟
熬夜后，第二天中午安排20～30分钟的午睡，最好在下午1～3点之间。这个时长可让你停留在浅睡眠阶段，醒来后不会昏沉，也不会消耗夜间睡眠驱动力。超过30分钟就会进入深睡眠，醒来反而更累。
A midday nap between 1 pm and 3 pm should stay under 30 minutes to avoid entering deep sleep, which can cause grogginess and disrupt nighttime sleep drive.
② 分多个时段补觉
这个方法适用于轮班工作者，下夜班后先睡3～4小时，然后起床活动、吃饭，再睡2～3小时。这种分段睡眠可模拟夜间睡眠的结构，且能避免单一长段补觉导致的生物钟紊乱。
For shift workers, sleeping 3‑4 hours after a night shift, then another 2‑3 hours after a period of activity, better mimics natural nighttime sleep and reduces circadian disruption.
③ 周末补觉不超2小时
周末比平时晚起不超过2小时。例如平时7点起床，周末最晚9点。超出这个限度会重置生物钟，导致周日晚上睡不着、周一早上起不来，形成恶性循环。
If one normally wakes at 7 am, weekend wake‑up should be no later than 9 am. Exceeding this can reset the biological clock, leading to Sunday night insomnia and Monday morning fatigue.
④ 调整好身体节律
补觉醒来后，尽快接触光照（自然光或光照治疗灯），帮助重置生物钟，减少补觉对节律的冲击。
Upon waking from recovery sleep, exposure to natural light or a light therapy lamp helps realign circadian rhythms and minimizes the impact of shift‑oriented rest patterns.
