Enhancing wakefulness -
A peak in wakefulness occurs in the evening a few hours before usual bedtime for a person on a normal, daytime activity schedule. This can be experienced as enhanced alertness in the early evening, even after being awake for long periods.

For example, a consistent sleep schedule is important. Try to go to bed and wake up at the same times each day, even on weekends and holidays.
Making your bedroom more sleep-appropriate and comfortable can also help. Take steps to keep it dark, cool, comfortable, and quiet, such as the following:. Developing a pre- sleep routine can also help prepare your body and mind for sleep.
This routine should include relaxing activities, such as:. Avoid loud noises, bright lights, glowing computer screens, and other stimulating things before bedtime.
Since stress often causes sleep deprivation , efforts to reduce stress are also important. For example, consider:. Prioritize self-care by eating a well-balanced diet, getting regular exercise, and making time for activities you enjoy.

How Well Do You Sleep? Health Conditions Discover Plan Connect. Sleep and Wakefulness. Medically reviewed by Raj Dasgupta, MD — By Amber Erickson Gabbey — Updated on May 26, Participants were screened based on their snoozing habits and were required to snooze 2 or more times per week.
The study involved 2 waking conditions in a counterbalanced order: snooze and no snooze, with participants maintaining their habitual sleep time. The snooze condition involved participants hitting snooze every minutes for 30 minutes before their final waking, while in the no snooze condition, participants woke abruptly without snoozing.
Participants underwent cognitive tests, mood assessments, and cortisol measurements upon waking and 40 minutes later. Sleep architecture was monitored using polysomnography. During the specific minute period prior to final waking, snoozing induced several sleep architecture changes compared with the no snooze condition.
Snoozing resulted in less sleep time, more arousals, and lower sleep efficiency. Participants in the snooze condition experienced more stage N1 sleep and less REM sleep. Notably, no participant experienced slow-wave sleep N3 during the snooze period. Cognitive performance improved with time awake, indicating sleep inertia.
Snoozing reduced the inertia effect, with participants performing better on arithmetic speed, episodic memory, and cognitive conflict cost in the Stroop test. However, these effects disappeared after 40 minutes. With snoozing, there was no effect on working memory or behavioral adjustment in the Stroop test.
Cortisol levels increased with time awake, but snoozing did not significantly influence cortisol response. Snoozing had no substantial impact on cognitive performance, sleepiness, or mood during lunchtime or in the afternoon.
These findings suggest that snoozing, despite altering sleep architecture, might mitigate sleep inertia temporarily, improving certain aspects of cognitive performance upon waking, but the benefits diminish relatively quickly. According to the results, snoozing for 30 minutes in the morning had minor effects on overall sleep but helped avoid waking up from deep slow-wave sleep.
While snoozing didn't significantly impact sleep or the mood of individuals, it appeared to be beneficial in reducing sleep inertia, and potentially enhancing cognitive function immediately after waking up. This suggests that snoozing might serve as a strategy to alleviate grogginess upon waking and improve cognitive performance right after getting out of bed.

Recent studies not only confirm the beneficial role of sleep in memory consolidation, but also point to a specific role for sleep slow waves. Thus, the implementation of methods to enhance sleep slow waves without unwanted arousals or lightening of sleep could have significant practical implications. Here we first review the evidence that it is possible to enhance sleep slow waves in humans using transcranial direct-current stimulation tDCS and transcranial magnetic stimulation. Since these methods are currently impractical and their safety is questionable, especially for chronic long-term exposure, we then discuss novel data suggesting that it is possible to enhance slow waves using sensory stimuli.
