Vacations allow for the natural regulation of three key hormones—cortisol, hunger hormones (ghrelin/leptin), and melatonin—by reconnecting with physiological needs rather than social constraints.

The creator highlights a solid biological reality: the reduction of professional or academic stress leads to a decrease in cortisol, which is confirmed by numerous observational studies on 'holiday well-being.' This phenomenon of 'disengagement fatigue' is also well-documented in stress psychology. Regarding nutrition, the shift to intuitive eating by following one's biological rhythm (rather than imposed social schedules) is supported by the principles of chrononutrition and mindful eating, although evidence of perfect regulation is nuanced by the vacation environment (which is often richer in temptations). The adjustment of melatonin through the elimination of a forced wake-up time is corroborated by chronobiology, which recognizes that respecting the natural circadian rhythm improves sleep quality (studies on sleep-wake rhythms). The advice is therefore generally based on real physiological mechanisms. There is no major exaggeration here; the creator uses accessible terms to popularize the body's capacity for self-regulation. The invitation to maintain these habits after the vacation is a healthy application of lifestyle hygiene.
