How much sleep does a person need?
Individuals vary greatly in their need for sleep; there are no established criteria to determine exactly how much sleep a person needs. Eight hours or more may be necessary for some people, while others may consider this to be too much sleep.
Does the amount of sleep we need change as we age?
Changes in the sleep cycle do occur with aging. Deep or slow wave sleep (Stage N3) sleep declines as we age, while light sleep (Stage N1) increases with age, so that older adults may spend less time in the more restorative stages of sleep and more time in lighter sleep. Older people are also more easily aroused from sleep. While some people believe that older adults need less sleep as they get older, there is no scientific evidence that older people need less sleep than younger adults.
What are and what causes sleep disorders?
Sleep disorders are disruptions of the sleep cycle or the quality of sleep. About 40 million Americans are believed to suffer from chronic sleep disorders, with millions more affected on an occasional basis. Doctors have defined over 70 different types of sleep disorders, but the most common sleep disorders are insomnia, sleep apnea, restless legs syndrome, and narcolepsy.
Insomnia is the perception of poor-quality sleep, including the inability to fall asleep or stay asleep. Because people differ in their need for sleep, there are no fixed criteria that define insomnia. Insomnia is very common and occurs in 30% to 50% of the general population. Approximately 10% of the population may suffer from chronic (long-standing) insomnia.
Zimovane Zopiclone 7.5mg is indicated for the short-term treatment of insomnia and appears to be associated with a very low risk of dependence, rebound insomnia, and withdrawal problems. Nevertheless some individuals do become dependent on zopiclone, and many of these have not experienced substance dependence or abuse previously. The approved data sheet for Zimovane advises no more than 4 weeks continuous treatment, and a maximum dose of 7.5mg (1 tablet) a day.
