Everyone sleeps. As a fundamental activity, sleep consumes roughly one-third of our lifetimes and can overpower all other needs. Research on normal sleep led scientists to recognize sleep disorders including insomnia, or difficulty falling asleep, and sleep apnea, which causes breathing to stop for extended periods during sleep.
Due to our high-paced lifestyles, we lack the time to get the sleep we need. Sleep deprivation has measurable negative effects on physical and mental health. If you haven't had a good night's sleep, you're likely to pay for it. If not addressed, the sleep debt you incur over time can result in serious physiological damage.
You should wake up refreshed in the morning without the use of an alarm clock and feel energetic all day.
