Research presented at the European Society of Cardiology congress indicates that moderate weekend sleep recovery may reduce the risk of hypertension. A study from Korea University involving approximately 40,000 adults found that sleeping slightly longer on weekends resulted in a 6% lower probability of developing high blood pressure. For physically inactive individuals, the benefit reached up to 9% when sleeping an additional 1 hour and 27 minutes.

However, researchers cautioned that excessive sleep—defined as sleeping more than four hours longer on weekends than on weekdays—is linked to an increased risk of hypertension due to circadian rhythm disruptions. 

Related psychological research suggests that mental well-being is also heavily influenced by the ability to achieve psychological detachment from work during vacations, as continuing professional duties during time off can diminish regenerative effects.
