Publisher's Synopsis
Sleep deprivation is a typical rest issue that can make it difficult to nod off, difficult to remain unconscious, or make you get up too soon and not return to rest. You maybfeel tired when you wake up. Sleep deprivation can sap your energy level and state of mind, as well as your wellbeing, work performance and personal satisfaction.
How much rest is sufficient changes from one individual to another, but most grown-ups need seven to eight hours every evening.
