Five Stages of Sleep
The Five Stages of Sleep
We generally think sleep is a simple process even when we are fully aware of the perils of lack of sleep.
Typical sleep passes through these five stages. EEG hints different levels of brain activity during the different stages of sleep.
On the fifth stage the condition reverses, with fast paced brain activities.
We pass through these five stages of sleep five to six times (5-6 cycles of sleep stages) in a typical 6 hour sleep.
It is not OK to wake one up when he or she is in third, fourth or REM stage of sleep.
We generally think sleep is a simple process even when we are fully aware of the perils of lack of sleep.
Typical sleep passes through these five stages. EEG hints different levels of brain activity during the different stages of sleep.
- Stages 1 through 4. The first four stages of sleep shows gradual decline of brain waves, suggesting lesser brain activity. As we reach the fourth stage, our brain activity is almost nil.
On the fifth stage the condition reverses, with fast paced brain activities.
- Stage five –Also known as REM Stage, REM sleep, characterized by Rapid Eye Movements and high levels of brain activities. Brain is highly active during this stage.
We pass through these five stages of sleep five to six times (5-6 cycles of sleep stages) in a typical 6 hour sleep.
It is not OK to wake one up when he or she is in third, fourth or REM stage of sleep.
