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

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。

Not sleeping at night not only harms one's wallet, but also makes it easy to fall into depression. Impulsive spending, self-doubt, sending messages to ex-partners... Why do some people tend to do "stupid things" at night?

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”？

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.

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。
