Dept Into Sleep?
Filed Under jurnal online
Sleep debt is the cumulative effect of not getting enough sleep. A large sleep debt may lead to mental and/or physical fatigue. There is debate in the scientific community over the specifics of sleep debt.
There is debate among researchers as to whether there is such a thing as sleep debt. The September 2004 issue of the journal Sleep contained dueling editorials from two of the world’s leading sleep researchers: David F. Dinges and Jim Horne. A 1997 experiment conducted by psychiatrists at the University of Pennsylvania School of Medicine suggested that cumulative nocturnal sleep debt affects daytime sleepiness, particularly on the first, second, sixth, and seventh days of sleep restriction.
Sleep debt has been tested in a number of studies, most notably by Klerman and Dijk through the use of a sleep onset latency test. This test attempts to measure how easily someone can fall asleep. When this test is done several times during a day, it is called a multiple sleep latency test (MSLT). The subject is told to go to sleep and is awakened after a short period of time to determine the amount of time it took to fall asleep.
However, one does not have to go to a sleep clinic to try this experiment; a home process has been considered: it involves relaxing quietly and alone for a short amount of time. If the feeling of sleep comes fairly easily, one is considered to have sleep debt. Some also suggest that the quality of sleep can have an effect on the level of one’s sleep debt.
The Epworth Sleepiness Scale (ESS) is among the tools used to measure potential sleep debt. Specifically, the ESS; created by Australian researchers, is a simple eight item questionnaire with scores ranging 0-24.
A January 2007 study suggests that saliva tests of the enzyme amylase could be used to indicate sleep debt, as the enzyme increases its activity in correlation with the length of time a subject has been deprived of sleep.
Ps: So, if you think sleep debt is something dangrous. You need to alert about that now. If not, you just wasting your life and might be affect your family.
