What Is sleep?
Until Quite recently, scientists ’believed that sleep was a simple, resting state, but it isntaskt 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.
What are the different stages?
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 ittasks 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. Why do we need sleep?
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 dontaskt 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.
How much sleep do we need?
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.
REM = rapid eye movement
Tips for getting a good night’s sleep
You should try to go to sleep and wake up at the same time every day. This helps your body to get into a routine. Avoid drinks like cola and coffee before bedtime - they contain caffeine that keeps you awake.
Don’t exercise or watch scary movies just before going to bed. This will wake your body up too much and you might find it difficult to fall asleep.
Have a calming bedtime routine, such as having a warm bath or reading.
