What is the latest research for sleep debt?

"The study was [researched in the Journal of the American Sleep Association]. After evaluating the study [through peer-review methodologies], we found some results that were inconsistent with the previous studies. It was the first time, for an extended study, we had to test multiple statistical analysis methods. When we tested the statistical analysis techniques [with SPSS], we were only able to find two groups of experiments that had a significant difference. In all the experiments involving a group, only one of them had a significant difference. We were also able to conclude that in a couple of experiments, we could not detect the difference, at all." - Anonymous Online Contributor

Unverified Answer

How serious can sleep debt be?

"Moderate sleep deprivation was associated with poorer executive function, but not with major depressive episodes nor poorer health. It can be concluded that sleep debt has a limited impact on mental health. Data from a recent study was based on the [NEURODNET-2] database, and other studies may reach different conclusions." - Anonymous Online Contributor

Unverified Answer

What is the average age someone gets sleep debt?

"When sleep debt was analyzed using age, age 5 accounted for 38.8% of the sleep debt. This is not necessarily surprising, given that sleep debt affects teens very early while they are transitioning into adulthood. There was a small effect of age 7, which was probably an artifact of the age 9 data being from individuals who were very close to their age of sleep debt. From 9 to 11, 11.6% of the sleep debt was accounted for by age 11. Because sleep debt is likely to affect youth much later in life, as well as early childhood, this is likely to have a large effect on older generations as well." - Anonymous Online Contributor

Unverified Answer

Have there been any new discoveries for treating sleep debt?

"Since the introduction of the first benzodiazepine derivatives, there had been very few effective hypnotic medications for sleep debt. Because of the development of the [benzodiazepine hypothesis], scientists began to search for a medication which would be effective for sleep debt. Benzodiazepines were thought to inhibit REM sleep and therefore lead to a'recovery effect' which was shown to be wrong because in the 1950s [benzodiazepines were used for anxiety and pain. Therefore, benzodiazepine sleep-inducing effects in the human body were really a side effect. The benzodiazepines were not effective in treating sleep debt and they were even harmful for it. The benzodiazepine hypothesis is disproven." - Anonymous Online Contributor

Unverified Answer

Does treatment improve quality of life for those with sleep debt?

"In a recent study, findings showed that the quality of life and sleep parameters improved in the study group in spite of the high sleep debt. Moreover, the high improvement in the parameters of QOL and sleep show the positive influence of the prescribed treatments on those with sleep debt who are suffering from insomnia." - Anonymous Online Contributor
