“不要相信晚上11点半后的大脑”上热搜，网友：已经开始后悔了

近日，“不要相信晚上十一点半后的大脑”的话题冲上热搜，引发网友热议。

The phrase "Don't trust your brain after 11:30 pm" has recently gone viral, sparking debate and playful comments among netizens.

有网友表示，一到晚上就做出莫名其妙的决定，不仅疯狂清空购物车，还老想吃东西。天亮后大脑宕机：这我买的？这我吃的？

Some netizens posted online that when night falls, reason often fades. Many find themselves clicking "buy" on overflowing shopping carts while reaching for late-night snacks. By morning, they wake up in disbelief, asking: "Did I really order this? Did I really eat that?"

晚上不睡觉，不仅钱包“受伤”，还容易陷入emo。

冲动消费、自我怀疑、给前任发消息……为什么有的人一到晚上就容易干“傻事”？

生命时报官方微博解释说，这在心理学上叫“深夜效应”：白天大脑分泌的血清素有助于维持情感稳定，深夜这种物质分泌水平会下降，情绪管理能力减弱，负面情绪被放大，容易因情绪波动造成冲动决策。

This late-night behavior is linked to what psychologists call the "mind after midnight" hypothesis. During the day, the brain releases serotonin, a chemical that helps keep emotions balanced. But as night falls, serotonin levels decrease, emotional control weakens, and small worries can feel magnified — often leading to impulsive decision-making.

而且，经历长时间的工作和活动，身体与脑力能量大量消耗，自控力会变差。到了晚上，大脑认知资源近乎枯竭，没有能力做出全面的分析，决策能力大幅下降。

After a long day of work, both physical and mental energies are drained, leaving self-control low. By night, the brain's cognitive resources are nearly exhausted, making critical thinking harder and causing good decision-making to falter.

此外，白天我们被各种社会角色束缚，言行保持着理性；可一到夜里，大家就容易过度关注甚至放大负面感受。

这种持续、反复自我审视会让人在不悦、悲伤中越陷越深，继而做出冲动、失控的选择。

“夜里，当我们的思绪集中在某些问题上时，它们可能会变得黑暗和可怕。但是到了早晨，所有这些又会像梦一样消失。”

如果你不仅晚上容易冲动，在白天也经常莫名愤怒、烦躁，那可能是身体严重缺觉了。

If you notice yourself not only acting impulsively at night, but also feeling unusually irritable during the day, it could be a warning sign that your body is struggling with serious sleep deprivation.

平时出现以下几种表现，其实都是身体释放的“缺觉信号”。

1. 倒头就睡

经常躺下后5分钟内就入睡，可能存在严重睡眠不足。

Falling asleep within just five minutes of lying down on a regular basis could be a sign of severe sleep deprivation.

2. 容易健忘

睡眠不足会导致难以形成记忆，逻辑思维不清。

Lack of sleep can make it harder to form memories and weaken logical thinking.

3. 饥饿感强

睡不够影响瘦素和生长素等激素，增加人们对食物的渴望。

Sleep deprivation disrupts hormones such as leptin and growth hormones, boosting cravings for food.

4. 笨手笨脚

睡眠不足会导致行走不稳、协调性差以及意外频繁发生。

Insufficient sleep can lead to unsteady walking, poor coordination, and frequent mishaps.

5. 更易走神

开车时错过公路出口、忘记转弯，或做事注意力不集中，都可能与睡眠不足有关。

Missing highway exits, forgetting to make turns, or struggling to stay focused on tasks may all be linked to a lack of sleep.

6. 总说陈词滥调

缺觉时，人更易口齿不清、爱用陈词滥调、说话单调。

When sleep-deprived, people are more likely to speak unclearly, fall back on clichés, and adopt a monotone voice.

所以大家一定要好好睡觉哇！大家有没有在晚上做出过“脑袋一热”的决定？来评论区聊聊吧！
