Sleep is the state of unconsciousness wakened by sensual or other stimulus. System and five senses are resting while sleeping. Systems function under coercion with autonomous nervous system. In spite of it, while systems participate in sleep in different rates, sense organs participate in sleeping completely. However, evocable unconsciousness is dominant against stimulus.
Physiology of sleep and significance of sleep
Toxic wastes accumulating in especially nervous system form the sleep. Nervous system inactivates these substances during sleep and rests. Sleeping need is a need eliminating physical and mental tiredness and making us energetic again. Quality of sleep and sleep irregularity is determinant for sleep disorder and sleep problems. Heart beat accelerates while sleeping and tension drops and breathing reduces and becomes deep, body temperature lowers, muscles relax, function of internal organs slow down and nervous system and sense organs rest.
Sleeping deeply varies by the person. Stimulation by sleep is related to the depth of sleep. Sleeping in a place with fresh air, peaceful and little light is more relaxing. Sleep starts when the centers in the brain making us awake become inactive. It continues with yawning due to lack of oxygen, closing the eyes and sleeping. When the centers making us wake up rest reach to the level of evaluating the stimulus, sleep ends and the person wakes up. REM sleep periods, instincts, subconscious and impulse of forward-looking living and doing something have effects on waking up.
Significance of regular sleeping
Sleeping is necessary for the liveliness activity like nutrition. It has the feature of nutrient and energy source for nervous system. Sleeplessness slows down reflexes. For this reason, sleepless people have accidents more. Productivity of sleepless person reduces. Cerebral activities slow down. Ideal and good sleep makes functions of person work better.
Toxic metabolism wastes accumulating in nervous system while sleeping become inactive. Other systems mainly nervous system rest partly or totally while sleeping. For this reason, time of sleep should be sufficient. There is a direct proportional connection between time of sleep and resting. Time of sleep varies by the age. Adults should sleep for 8-10 hours a day. It extends to 22 hours for infants. It is 14 hours for children and 5-6 hours for old people. Patients should sleep longer. Sleeping is a requirement for mental and physical resting.
Sleep disorders include parasomnia with abnormal behaviour while sleeping, nightwalking, sleep terror, insomnia, confusional waking up, eating while sleeping, Ekbom syndrome and sleep-periodical leg movement disorders. Since sleeping is the basic need of the body, reasons of sleep disorders should be determined and treated.
Sleep laboratory evaluations are carried out at Kent Hospital sleep disorders unit for the diagnosis of sleep disorders becoming more and more significant.
