Sleep at different ages
Here, you are in light stage sleep, which means that you're somewhat alert and can be easily woken. Stage Two: During this stage, which is also fairly light, the brain produces sudden increases in brain wave frequency known as sleep spindles. Then brain waves slow down. You won't experience any eye movement or muscle activity. At this point, it becomes a little harder for you to be awakened, because your body becomes less responsive to outside stimuli.
The brain produces even more delta waves and you move into an even deeper, more restorative stage of sleep next. It's most difficult to wake up during this stage.
