"Effective intervention to increase duration of sleep and improve quality of sleep could be an under-appreciated avenue for reducing the risk," study researcher Dr. Li Li, M.D., Ph.D., said in a statement.
Sleep during depressive episodes is characterized by a reduction in SWS, or increased latency to SWS, increased duration of R sleep, shortened latency to R sleep, continuity disturbances, and decreased TST [ 9- 12].
In clinical studies, increased duration and intensity of NREM sleep during illness are associated with an improved prognosis, but occur at the expense of REM sleep [ 11, 13, 18].
This is consistent with our study where LM100 and LM200 significantly increased the duration of sleep.
As test sample decreased latent period (onset of sleep) and increased the duration of sleep, the LM showed dose dependent sedative effects which were statistically significant (p <0.05).
Thiopental sodium induced hypnosis test revealed that all extracts, at the doses of 100 and 200 mg/kg body weight, dose dependently induced sleep at a rapid stage as compared to control and increased the duration of sleep.
Eliminating interns' extended work shifts will increase their duration of sleep, reduce attentional failures, and decrease rates of medical errors as compared with traditional work schedules.
The scale does not include items for increased appetite or duration of sleep, anhedonia, psychomotor agitation or retardation, guilt, or suicidal thoughts [ 20].
Both earplugs and eye masks, and oral melatonin, significantly improved sleep quality, in addition to shorter sleep-onset latency and reduced number of arousals and awakenings; melatonin also increased the duration of REM sleep stage and total sleep time.
All doses of the extracts produced a dose dependent decrease in onset of sleep and increase in duration of sleep.
In agreement PACAP administration in rats increased the duration of REM sleep [73]; however, PACAP-38 [74] administration in healthy controls had no impact on the time spent in each sleep stage, but did modulate slow wave sleep.
