Sleep and Health: Role of Dopamine

Introduction: Sleep is an important part of people’s lives and proper sleep is a prerequi- site for good health. Purpose: The purpose of this chapter is to highlight the importance of sleep in the pro- motion of health, sleep-related patients, and dementia at various stages of the age of the immortal. It also refers to sleeping on Parkinson’s disease and dopamine. Material & methods: An extensive review of the relevant literature was performed via electronic databases (Medline, PubMed, Cinahl and Google Scholar) and Greek and international journals. Results: Sleep is described as a special state of consciousness. It is composed of phases and is characterized as relatively unresponsive to the surrounding area. It is a periodic situation. The fall of consciousness during sleep provides time for the body systems to be reconstructed and renewed. Thus, sleep is a corrective mechanism that contributes to the regeneration of the person’s normal and emotional state. It occurs cyclically, usually once a day. Sleep is divided into two types, known as REM (Rapid Eye Movement), and NREM (Non Rapid Eye Movement). Conclusion: Sleep occupies about one third of our total lifetime and is a very important biological function. Its functional significance is related to the resting of brain function and to the proper functioning of memory and learning.
