To remain calm and focused, prioritize getting sufficient sleep, and if you have had a poor night's rest, avoid externalizing your thoughts (complex conversations, decisions, social interactions) as much as possible.

The first point regarding the importance of sleep for emotional and cognitive regulation is widely supported by scientific consensus, notably through meta-analyses showing that sleep deprivation impairs impulse control and mental clarity. The second point is an interesting approach related to managing cognitive load. Observational studies and research in cognitive neuroscience confirm that fatigue reduces our ability to regulate our emotions and social reactions ('reactive amygdala' effect), which makes complex interactions more taxing. The idea of limiting cognitive output after a poor night is a mental energy management strategy consistent with the concept of a limited 'cognitive reservoir.' This advice is therefore based on real physiological mechanisms, although practical application obviously depends on an individual's life obligations. It is not an absolute truth, but a pragmatic recommendation to protect one's mental well-being during periods of biological vulnerability.
