Until quite recently, scientists believed that sleep was a simple, resting state, but it isn’t like this at all! When we sleep, our body temperature drops, our heart rate and other bodily functions slow down, but our brains stay very active. There are four different stages of sleep that repeat every 90 to 110 minutes. Stages N1 and N2 are light sleep and we can easily wake up. In stage N3, we sleep more deeply, and it’s harder to wake up. Some people may also sleepwalk or talk in their sleep. The last stage is REM sleep. Our eyes move around, our brain is very active, and we have a lot of dreams. While we sleep, our brain sorts through information, replaces chemicals, repairs cells, and solves problems. Lack of sleep seriously affects our mind and body. When we don’t rest enough, we may feel grumpy, forgetful and unable to concentrate. Lack of sleep can also affect our immune system. Over a long time, it may cause depression and personality changes and eventually even shorten our life. It’s different for everyone, but on average, babies need 16 to 18 hours of sleep, teenagers about 9 and adults about 7 to 8.
