The phrase "Don't trust your brain after 11:30 pm" has recently gone viral, sparking debate and playful comments among netizens.
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?"
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.
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.
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.
1.Fall asleep instantly
Falling asleep within just five minutes of lying down on a regular basis could be a sign of severe sleep deprivation.
2.Prone to forgetfulness
Lack of sleep can make it harder to form memories and weaken logical thinking.
3.Strong sense of hunger
Sleep deprivation disrupts hormones such as leptin and growth hormones, boosting cravings for food.
4.Physically clumsy
Insufficient sleep can lead to unsteady walking, poor coordination, and frequent mishaps.
5.Easily distracted
Missing highway exits, forgetting to make turns, or struggling to stay focused on tasks may all be linked to a lack of sleep.
6.Tends to speak in clichés
When sleep-deprived, people are more likely to speak unclearly, fall back on clichés, and adopt a monotone voice.
So please, get some proper rest!
