Scientists propose the Mind After Midnight hypothesis, arguing that the brain shifts into a markedly different mode when we stay awake after the biological night begins. During these hours, attention fixes more easily on threats, mood tilts negative and the reward system becomes more impulsive. Together, these changes make harmful actions, such as substance use, self-harm or rash decision-making, more appealing and less inhibited.
The team suggests this night-time “risk mode” is an evolutionary hang-over: in darkness our ancestors needed to react quickly to danger, so the brain prioritized vigilance over careful deliberation. In the modern world, however, that same shift can push tired students, shift workers or anyone lying awake past midnight toward despair or dangerous cravings.
Because most research on sleep focuses on next-day effects, the authors call for dedicated studies of what actually happens in the brain while people are awake at night, especially for groups who must work through the small hours. Understanding these mechanisms, they argue, is essential for preventing night-time accidents, overdoses and suicides.
