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. [] Key Method 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…

Self-Awakening, Sleep Inertia, and P3 Amplitude in Elderly People
It is well known that sleepiness is sometimes experienced in the afternoon. A short afternoon nap is thought to be effective in reducing sleepiness. However, sleep inertia occurs even after a short
Self‐awakening improves alertness in the morning and during the day after partial sleep deprivation
TLDR
The results showed that self‐awakening improved alertness (assessed by response speeds) by reducing sleep inertia and alleviated daytime sleepiness heightened by partial sleep deprivation.
Electroencephalogram activity before self-awakening
It has been reported that self-awakening, the ability to awaken without using an alarm at a predetermined time, can reduce sleep inertia immediately after awakening. To clarify the
Indoor exposure to natural bright light prevents afternoon sleepiness.
TLDR
Short-term exposure to natural bright light significantly improved afternoon arousal levels, as measured by the Karolinska Drowsiness Test and Alpha Attenuation Test, and could be used in work settings in which napping is not permitted.

The siesta and ambulatory blood pressure: is waking up the same in the morning and afternoon?
TLDR
There is a higher rise of HR and double-product in the morning than after the siesta, which may indicate a lesser increase in cardiac oxygen consumption and, therefore, lesser potential for acute ischemia.
Siesta and ambulatory blood pressure monitoring. Comparability of the afternoon nap and night sleep.
TLDR
The marked decline in blood pressure during daytime sleep suggests that sleep itself, rather than an endogenous circadian rhythm, is responsible for the blood pressure dip observed during both daytime sleep and nighttime sleep.
The siesta in the elderly: risk factor for mortality?
TLDR
A prospective population-based cohort study of 455 70-year-old residents of Jerusalem, Israel, using self-reported siesta at baseline and 6 1/2 years of total mortality data found that the siesta remained predictive of mortality.
Subjective and objective confirmation of the ability to self-awaken at a self-predetermined time without using external means.
TLDR
Results show that many people have the ability to regularly awaken themselves from sleep at a desired time and that such an ability is of practicable utility.
Nocturnal Sleep at a Predetermined Time in Healthy Undergraduate Students
TLDR
It is suggested that psychological stress related to time pressure might influence sleep onset and could have induced spontaneous awakenigs from sleep.
