It is with particular interest that I introduce the work of Viorela Popescu, PhD, Lecturer at the Bucharest Academy of Economic Studies (Department of Physical Education and Sport), a study which brings to the attention of readers the significance of passive resting among young university students aged 18 to 20, in supporting the recovery of the body following sustained physical or intellectual exertion. The aim of this book is to assess the level of awareness among students at AES regarding proper hygienic practices that contribute to the maintenance of optimal health and the improvement of physical condition. The empirical research is grounded in the central hypothesis that, despite nighttime sleep being the primary mode of recovery, students often do not attain adequate rest - neither in terms of duration nor quality. Although young students may be theoretically aware of the importance and role of rest after exertion, particularly through sleep, in practice they struggle to observe the recommended duration necessary for effective recovery. The author emphasizes that both the quantity and quality of sleep are vital for restoring the human body to an efficient and functional state.
