Chronically sleep-deprived people, however, continue to rate themselves considerably less impaired than totally sleep-deprived participants. [57] An indicator of sleep propensity can also be seen in the shortening of transition from light stages of non-REM sleep to deeper slow-waves oscillations can also be measured as indicator of sleep propensity. [98] A 2017 review indicated that older adults do not need less sleep, but rather have an impaired ability to obtain their sleep needs, and may be able to deal with sleepiness better than younger adults. [9][10][11], Primary insomnia is a sleep disorder not attributable to a medical, psychiatric, or environmental cause. Found inside – Page 36Now you know that sleep is controlled by a biological process and that brief awakenings (night wakings) are a normal human sleep, regardless of age. As the name suggests, an innerspring mattress uses a system of connected metal springs, or coils, to support the weight of your body. 18th-century beds in Germany were the first to use feather coverings for added comfort.
