The Significance of Quality Sleep for Health
Let’s discuss the importance of enough sleep for health. Teenagers need a lot of sleep. How much? That depends on the person but usually about nine hours a night – that’s more than adults!
It’s difficult for teenagers to wake up early and to go to sleep early. Often they feel lively at night when adults feel sleepy. Many teenagers have the energy to play computer games until late at night but can’t find the energy to get out of bed in time for school. Is it just laziness or is it something more? That’s because teenagers’ brains produce melatonin (a hormone which makes you sleepy) later. At night our body produces the ‘darkness hormone’ melatonin which helps us to fall asleep. Most adults start to produce melatonin at about 10 p.m. Research has shown that teenagers start to produce the hormone at 1 a.m. In other words, teenagers are being kept awake by their bodies and there is not much they can do about it. The fact that they play computer games and watch television late at night stimulates the brain even more and makes it harder for them to fall asleep. When you see bright lights, your brain stops making melatonin. That means you can’t sleep well.
One thing is for certain – sleep is extremely important for teenagers for several reasons.
- Sleep is essential for the release of growth hormones for physical growth and muscle development.
- Sleep is necessary for good memory and concentration, problem-solving, and decision-making. Teenagers who get enough sleep are more focused during the day. This is particularly important for academic performance or participating in sports.
- Quality sleep is linked to a strengthened immune system and that helps to fight off illnesses and infections.
- Sleep helps regulate hormones, including those responsible for stress, mood, emotions, and appetite.
- Sleep improves overall mental health.
Most teenagers do not get enough sleep. Lack of sleep results in bad moods, irritability, increased stress levels and sometimes depression.
If you have problems falling asleep, you should think about the following:
- establish a a regular sleep schedule
- do not drink chocolate, tea and coca-cola in the evening because they have caffeine and they keep you awake
- do not eat before you go to bed because too much food makes it difficult for your body to relax
- don’t exercise before bedtime
- create a comfortable sleep environment
- minimize screen time before bedtime.
Five Stages of Sleep
Every person goes through five stages of sleep. To feel good we need to go through each stage every night.
During stages 1 and 2 you sleep lightly. It is easy for someone or something to wake you. During stages 3 and 4 you sleep deeply. It is not easy for anyone to wake you. You hear no sounds and see no lights.
Then comes the last stage of sleep. It is called REM (rapid eye movement). This is the stage in which you dream. You breathe more quickly than in the previous stages. Your eyes move rapidly under your eyelids and you dream.
There are all kinds of dreams: good ones, bad ones and nightmares. You need your dreams. You dream more if you have a special problem. Dreams help you solve your problem and give you answers to some questions. Actually, you dream four to six
times during the REM stage. Very often you don’t remember what you have dreamt about.
