After 2 a.m., our ability to think rationally collapses, pulling us toward catastrophic thinking; therefore, one must go to sleep because decisions made at this hour are systematically bad.

Research surprisingly supports the underlying idea behind this advice. In 2022, researchers led by Dr. Elizabeth Klerman (Harvard) formalized the "Mind After Midnight" hypothesis in a theoretical review based on observational data. This hypothesis suggests that nocturnal wakefulness, being out of sync with our biological clock, impairs information processing and emotional regulation, fostering negativity and impulsivity. However, the absolute tone claiming that every decision after 2 a.m. is necessarily bad is an amusing exaggeration drawn from a television series. Furthermore, this strict 2 a.m. threshold has no universal biological basis, as lucidity depends primarily on chronotype (early bird or night owl) and accumulated sleep debt. Nevertheless, prioritizing sleep over rumination when faced with dark late-night thoughts remains an excellent rule for a healthy lifestyle.
