Did you know that sleeping is how your body and mind rests, and restores its energy levels? It is an active state that affects both your physical and mental health. Every night, everyone goes through what is called a sleep cycle. You may be wondering what exactly this is. During the sleep cycle, we go through 5 stages. Theses stages are 1,2,3,4, and REM (rapid eye movement). This means that when you are sleeping, your eyes move in all different directions very quickly, and it happens 90 minutes after you fall asleep. A complete sleep cycle lasts about 90 to 110 minutes. In stages one, two, and three you are in what is called non- REM. It is a very light sleep and you can be woken up within 5-15 minutes. Then stages, four, and REM are the deep stages of sleep. Over the course of a typical night, we cycle through the stages of sleep about five times. You may not be aware, but sleep affects both infants and adults very differently. Throughout our lifetime, the amount of time that we spend each day sleeping declines. When babies are born, they need the most amount of sleep. Each day, newborns need anywhere from 16 to 20 hours a sleep each day. Then, when the child gets to one-year-old up to four years old, they only need about 11 or 12 hours of sleep a day. As the child grows older and older, there sleep time a day decreases. When one becomes an adult, they only need up to eight hours of sleep a night. As you can see, as we get older our bodies change and requires less sleep.
