Do we really want more sleep? A population-based study evaluating the strength of desire for more sleep.
OBJECTIVE
The sleep literature increasingly points to an apparent chronic sleep debt in the general population. We investigated this by examining perceived shortfalls in daily sleep, using more indirect questioning methods.


METHODS
To determine perceived sleep deficits, 10,810 adults completed a simple questionnaire, which avoided leading questions and provided information on sleep length, daytime sleepiness, desired sleep length, a choice of attractive daytime activities in a "free hour", and "stressful lifestyle". From this we assessed whether deficits were reflected by increased daytime sleepiness or opting for more sleep when given attractive waking alternatives. Respondents were divided according to age and sex.


RESULTS
Half of men and women seemed to desire more sleep, but this apparent sleep deficit was not correlated with daytime sleepiness, for any age or sex group. Irrespective of deficit, few people opted for sleep when given waking alternatives. "Stressful lifestyle" was independently related to this sleep deficit.


CONCLUSIONS
Desiring more sleep may also be synonymous with a need for more "time out", as sleep deficit was unrelated to daytime sleepiness but rather related to "stressful lifestyle." Extra sleep may not be the only anodyne for sleep deficit.
