You wake up at 3 am because this is the time you shift from a deep sleep into a lighter sleep. If you go to bed at 11 pm, by three in the morning you're mostly out of deep sleep and shifting into longer periods of lighter sleep, known as REM.
Even though noradrenaline technically causes the brain to wake up more than 100 times a night, we do not think of it as waking up. "Neurologically, you do wake up, because your brain activity during these very brief moments is the same as when you are awake.
Your central circadian clock, located in your brain, tells you when it is time for sleep. Other circadian clocks are in organs throughout your body. Your body's internal clocks are in sync with certain cues in the environment. Light, darkness, and other cues help determine when you feel awake and when you feel drowsy.
Two internal biological mechanisms–circadian rhythm and homeostasis–work together to regulate when you are awake and sleep. Circadian rhythms direct a wide variety of functions from daily fluctuations in wakefulness to body temperature, metabolism, and the release of hormones.
“Heavy sleepers should look for alarm clocks with extra loud settings, adjustable volume levels, no-snooze button, vibrating functions, and bed-shaking capabilities to help wake them up,” Dr. Harris says.
In October of 2017, Wyatt Shaw from Kentucky fell asleep for 11 days. He was just seven years old and doctors ran several tests with no conclusive explanations.
These four sleep stages are called non-rapid eye movement (non-REM) sleep, and its most prominent feature is the slow-wave (stage IV) sleep. It is most difficult to awaken people from slow-wave sleep; hence it is considered to be the deepest stage of sleep.

There are four likely culprits behind your low energy: your sleep need is more than eight hours, you're getting less sleep than you think, you've got sleep debt to pay back, or you're out of sync with your circadian rhythm.
If you are struggling to wake up in the morning, it's important to rule out medical conditions such as sleep apnea, narcolepsy, and chronic fatigue syndrome. However, if you have been diagnosed with one of these conditions, your inability to get out of bed may be related to your diagnosis.
And while the occasional long sleep is generally nothing to worry about, oversleeping several days a week could be a sign that something more serious is going on.
Turn down your stress levels
Stress is also why you want to sleep but your brain won't stop talking to itself. That's because when the mind is under pressure, it releases a hormone called cortisol, which is also what the body uses to wake you up in the morning.
A sound that starts relatively quiet and calm and gets progressively loud and energizing is most effective, Giordana says. “Rather than just literally pulling them from sleep into the wakeful state, you're sort of gently escorting them into the wakeful state,” Giordano says.
Without a doubt, the winner of 'The World's Loudest Alarm Clock' title, and part of the Sarabec catalogue of loud alarm clocks, is the Sonic Bomb. It boasts an excessive alarm that can be set up to reach 113dB if necessary.
