Sleep medicine is a medical special service devoted to the diagnosis and therapy of sleep disorders and disturbances. Sleep Disorders are widespread and can have significant consequences for affected individuals. Sleep disorders are the changes in sleeping patterns. Symptoms and Signs of sleep disorders include excessive daytime sleepiness, irregular breathing and increased movement during sleep, difficulty sleeping, and abnormal sleep behaviors.
A sleep disorder can affect your overall health, safety and quality of life. With diagnosis, doctors can treat most sleep disorders effectively. Sleep disorders are the conditions that prevent a person from getting restful sleep and, as a result, can cause daytime sleepiness and dysfunction. There are so many different types of sleep disorders. The most important sleep disorders are: Sleep apnea, Insomnia, Restless legs syndrome, Narcolepsy. Insufficient sleep is associated with a number of chronic diseases and conditions such as diabetes, cardiovascular disease, obesity, and depression. Not getting enough sleep is associated with the onset of these diseases and also may complicate their management and outcome.The amount of sleep that a person needs to function in a normal manner depends on several factors, including age. Infants sleep most of the day (about 16 hours); teenagers usually need about 9 hours a day; and adults need an average of 7 to 8 hours a day. Although older adults require about as much sleep as younger adults, they usually sleep for shorter periods and spend less time in deep stages of sleep.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
