A Detailed Study of Different Stages of Sleep and Its Disorders – Medical Physics

Abstract

After laborious work in day or night, different parts of our body get tired and require a complete rest; just like the machines running continuously for long time are switched off to prevent overheating, which may cause firing also. Sleeping is a process associated with closed eyes which gives a complete rest for our mental and physical activities except for the functioning of some vital organs like heart, lungs, and process like blood circulation, digestion etc. The duration of sleep is not a constant throughout the period. It depends on different factors like age group, type of hard work, diseases associated with human beings etc. In the present study we have discussed in detail about the different stages of sleep, mechanism of sleep, diseases related to sleep disorders and remedial treatments.
