Vacation
A significant association was found between paid vacation days and the odds of depression among women. For every ten additional days of paid vacation leave, the odds of depression over a decade during mid-adult life was 29% lower. Stronger effects were observed among white women and women with ≥2 children. No association was observed in men.[1]
Twenty-seven percent of the variance of the change of recuperation and 15% of the change of exhaustion could be explained. Recuperation was facilitated by free time for one's self, warmer (and sunnier) vacation locations, exercise during vacation, good sleep, and making new acquaintances, especially among vacationers reporting higher levels of prevacation work strain. Exhaustion was increased by vacation-related health problems and a greater time-zone difference to home, and was reduced by warmer vacation locations. Health-related vacation outcome is significantly affected by the way an individual organizes his or her vacation.[2]
One single short vacation of four nights has positive effects on the well-being, recovery, strain, and perceived stress of middle managers, independent of the mode of vacation. These effects are measurable even 30 days (recovery) and 45 days (well-being and strain) after the end of the short vacation.[3]
