“…In specification, the experimental task of vigilance reaction is relatively bald, such tasks may easily induce the subjects who didn't take LTN to desire sleep, and the result is that their performance is worse than the subjects who took LTN. Hayashi et al also took for that nap could reduce human sleepiness and enhance vigilance [7,8,12]. However, as for short-term memory and arithmetic calculation, these tasks' mental workload are relatively overload, the subjects who didn't take LTN weren't easily to stimulate sleepiness, and the result is that their performance are the same as those who took LTN.…”

“…In the countries which have the custom of siesta such as Latin America and Spain, people take a nap to avoid the hottest part of the day 4) . Even in the countries which do not have the custom of siesta, a short nap (i.e., "power nap") is recommended to reduce afternoon sleepiness 5,6) . Many studies have indicated that psychomotor vigilance performance and subjective sleepiness improve after a short nap [5][6][7][8] , suggesting napping as an effective measure to maintain productivity and safety at work.…”

Self-Awakening Prevents Acute Rise in Blood Pressure and Heart Rate at the Time of Awakening in Elderly People

Self-awakening, waking up at a designated time decided before sleeping, could prevent failure in the blood circulation vessel system such as heart attack, acute increases in heart rate or blood pressure upon waking. Previous research showed that anticipatory changes occurred in heart rate prior to awakening from a short nap by means of self-awakening for young participants. However, the effects of self-awakening remained unclear for elderly people. The present study examined the effects of self-awakening on heart rate and blood pressure in a short afternoon nap (20 min) among the elderly. Nine participants [74.1 (SD = 5.01) years old] underwent both self-awakening and forced-awakening conditions. In the self-awakening condition, it was revealed that blood pressure gradually increased before the scheduled time of awakening, and that heart rate did not show a rapid increase at arousal. In contrast, forced-awakening induced acute increases in both heart rate and blood pressure. These results suggest that self-awakening facilitates a more smooth transition from sleep to wakefulness via autonomic activation before the time of self-awakening.

“…This may be explained by the fact that they had taken a nap for about 90 min during the daytime. A daytime nap of less than 20 min is known to have a substantial effect on decreasing fatigue [10][11][12] . As stated above, because home-based workers work at home, under their own management, the opportunities to take a nap when necessary appear to be an advantage in reducing fatigue.…”

Actual Conditions of Work, Fatigue and Sleep in Non-Employed, Home-Based Female Information Technology Workers with Preschool Children

We conducted a study on time budget and fatigue feelings over a two-month period of 12 non-employed, home-based female workers using computers (mean age 35.2 yr). All of them had at least one preschool child. The actual amount of work done by these women and the related effects on the fatigue feelings and sleep were investigated. The results showed that the work done was characterized by involving many night hours, irrespective of the day of the week. The degree of subjective fatigue was not dependent on the number of hours worked, but affected by the time at which the work of the day was completed. This tendency was notable after one o'clock in the morning when the work was completed. Those who followed such a work pattern took daytime naps, although a quality of the subsequent nighttime sleep taken might be poor. They took a nap around 14:00 but not around 19:00. The sleep strategies were thus shown to be affected by home-based work. A need is suggested to support these workers in adjusting work time distribution and taking sleep patterns adapted to individual conditions.
