Effects of a short midday nap on habitual nappers' alertness, mood and mental performance across cognitive domains.

abstract：:Self-reported short or long sleep duration has been repeatedly found to be associated with increased mortality and health risks. However, there is still an insufficient amount of detailed knowledge available to characterize the short and long sleep duration groups in general population. Consequently, the underlying me...
