Why do I feel higher once I wake myself up than if my alarm or another person wakes me up? – Kaleigh H., age 11, Oklahoma
We've all experienced it: You're in the midst of a phenomenal dream. Maybe you're flying. As you fly through the air, you meet an eagle. The eagle looks at you, opens its beak and – beep! Beep! Beep!
Your alarm goes off. Dream over, time to get up.
Many people – children and adults alike – notice that once they get up naturally, they feel more alert than when an alarm or one other person, similar to a parent, wakes them up. Why is that?
I am a neurologist. One who studies the brain, especially what happens within the brain if you find yourself sleeping. I also care for kids and adults who do stay awake well and need to sleep higher. My research involves working with parents to show their children good sleep habits.
To understand how you can improve sleep, and why waking up naturally helps you’re feeling more alert, you must start by understanding sleep cycles.
Sleep cycle
gave Sleep cycle consists of 4 stages. One of them is REM, which stands for rapid eye movement. The remaining three are non-REM stages. When you sleep, you first go right into a state of sleep called non-REM stage 1.
This is followed by the deeper stages of sleep, called non-REM stages 2 and three. Each stage of non-REM is deeper than the previous one. Then, about 90 minutes after you go to sleep, you enter the fourth stage, which is REM sleep. This is the stage of sunshine sleep where you do most of your dreaming. After a couple of minutes, you fall back into non-REM sleep.

These cycles repeat themselves throughout the night, with most individuals having 4 to 6 cycles of non-REM sleep together with REM sleep each night. As the night progresses, there are cycles of less non-REM sleep and more REM sleep. This is why it will be important to get enough sleep, in order that the body can recuperate. There is enough of both REM sleep and non-REM sleep.
REM vs. non-REM sleep
How do researchers like me know if an individual is in non-REM versus REM sleep? In the sleep lab, we are able to tell by their brain waves, eye movements and the stress of their muscles, similar to the chin. They are measured by placing sensors called electrodes on the scalp, across the eyes and on the chin.
These electrodes pick up brain activity, which varies from waves which might be short in amplitude (wave height) and comparatively fast to waves which might be high in amplitude (a protracted wave) and comparatively slow. There are When we’re awake, the wave height is lower and the waves are relatively fast. In contrast, the waves are louder and slower during sleep.
Non-REM stage 3 has the longest and slowest waves of all sleep stages. In REM sleep, brain waves are shorter in amplitude and comparatively faster, and eye movements are also faster. People need each non-REM and REM phases for a healthy brain, in order that they can learn and remember.
Waking up naturally
When you get up on your personal within the morning, it's often as if you happen to've reached the tip of any sleep phase. Think of it like getting off at a train station. But when an alarm or another person wakes you up, it's like jumping off a train between stops, which may feel jarring. That's why it's good to get up naturally each time possible.
People can actually train their brains to get up at a consistent time every day, which is a natural stopping point. The brain has an internal 24-hour clock that tells whenever you go to sleep and whenever you get up. It belongs to us. Circadian rhythm.
Training the brain to get up at a consistent time
First, it's essential to go to bed at a consistent time that permits you to get enough sleep. If you not sleep late doing homework or taking a look at your phone, it may interfere with getting enough sleep and make you depending on the alarm — or your parents — to wake you up.
Other things that may make it easier to go to sleep at a healthy time include getting physical activity in the course of the day and avoiding coffee, soda or other drinks or foods with caffeine. Physical activity increases brain chemicals that make it easier to go to sleep, while caffeine does the other and keeps you awake.
Second, you must concentrate on the sunshine in your environment. Too much light late within the evening, including from screens, can interfere along with your brain's production of a. A chemical called melatonin Which promotes sleep. But whenever you get up within the morning, you must be exposed to light.
Morning light helps you synchronize or align your circadian rhythm with the surface world and makes it easier to go to sleep at night. The easiest approach to do that is to open your shades or curtains in your room. In the winter, some people use light boxes to simulate sunlight, helping them align their rhythms.
Benefits of a superb night's sleep
sleep routine includes each bedtime and wake-up time and getting enough sleep frequently. It usually means 11th of September hours for school-age children who should not yet teenagers, and 8-10 hours for teenagers.
This will make it easier to perform higher at school, improve your mood, maintain a healthy weight, and promote many other elements of health.
