How does your brain wake up from sleep?
How Our Brains Wake Us Up
- One of the systems in the brain that wakes us up is the reticular activating system (RAS) - a part of your brain located just above your spinal column that acts like a gatekeeper or filter for your brain, making sure it doesn’t have to deal with more information than it can handle.
- The RAS can sense important information and create neurochemicals that wake up other parts of the brain. It also keeps you awake throughout the day.
- Once the RAS switch turns on, it can take some time for your whole brain and body to wake up. This is because it takes a few minutes to clear all the “sleepy” neurochemicals from your brain, which is why you may feel groggy when an alarm clock wakes you up.

The lifestyle imbalance
Thomas Edison said that sleep is "a bad habit." Like Edison, we seem to think of sleep as an adversary and try to fight it at every turn. The average American sleeps less than the recommended seven hours per night, mostly due to electric lights, television, computers, and smartphones.
However, we are ignoring the intricate journey we're designed to take when we sleep.
Stage One Sleep
When we fall asleep, the nearly 86 billion neurons in our brain starts to fire evenly and rhythmically. Our sensory receptors become muffled at the same time.
The first stage of shallow sleep lasts for about 5 minutes.

The Enemy of Sleep
Our body will take care of itself if left on its own. It is our mind which is the culprit, running like a motor, inducing low-grade anxiety inside us.
Sleep is not something you have to do, but something which happens naturally to you. If an insomniac forgets that he is an insomniac, he will have a good night's sleep.
