The community recognizes the potential benefits of this practice for mental relaxation, but is strongly divided on its practical feasibility, mainly due to concerns regarding personal safety. From a scientific standpoint, the idea of 'recalibrating the nervous system' through gentle movement and exposure to darkness aligns with the principles of stimulus control therapy, used in behavioral sleep approaches (a method validated by meta-analyses, e.g., Mitchell et al., 2012). Moderate physical activity can effectively help reduce cortisol, but intense exercise right before bedtime is often discouraged because it can increase body temperature. Exposure to natural light (or its absence) plays a key role in regulating the circadian rhythm, although the effect of night walking specifically on sleep remains largely anecdotal rather than clinically proven. In summary, the 'relaxation' and 'disconnection' aspect is supported by the science of stress, but the overall advice is considered a highly contextual individual solution.
