How does the miracle of sleep happen?
We know that when brain cells or neurons fire while we’re awake, they release special molecules that attach to other neurons. This is when the magic begins.
These ‘other’ neurons absorb chemicals in the brain that make them sleepy. This means that only part of the brain sleeps which accounts for the “alertness” that’s experienced when we sleep.
While in deep sleep, the brain is still active. We can sleepwalk with our eyes open and have no conscious awareness of our activities. We can learn while snoozing.
Extended periods during the day of brain “laziness” and physical rest won’t make you tired enough to fall asleep because not enough of the special molecules were released.
A key to a good night’s sleep is a balance of both brain and physical activity.
