3. What is sleep? What are the stages of sleep? It’s a complex process that has 2 main stages: 1. sleepiness 2. A man is very susceptible to any irritant 3. The process of our organism’s recovery 4. The deepest, the longest and the most useful stage It’s time to wake up!!! I. Slow (deep) sleep II. REM sleep (fast) Our brain is active. We see and remember dreams.

4. How much sleep is enough? Sleep needs vary from person to person… Newborns Preschool children Teenagers Adults ? 16-18 hours 10-12 hours 9 hours 7-8 hours

5. Good!!!Bad… We think and react clearly We rest well We function well We can solve our problems We are more likely to make bad decisions and take more risks We are irritable and our poor behaviour effects our attitude to people The risk of having high blood pressure, heart diseases

6. Go to bed and wake up at the same time Exercise is great but not before bedtime Avoid caffeine and nicotine Avoid alcoholic drinks before bed Avoid large meals late at night Avoid medicines that delay or disrupt your sleep Don’t take naps after 3 p.m. Try to get outside in natural sunlight at least 30’ each day Relax before bed Take a hot bath before bed Have a good sleeping environment Don’t lie in bed awake See a doctor if you continue to have trouble sleeping!!!

7. Sleep, dreams and happiness There’s nothing mysterious or threatening about sleep and dreams. We must see Objective Reality as clearly as possible. Sleep allows us to face every new day with optimized mental and physical resources. Dreams reactivate and refresh our physiological systems. If you want to be happy and free from your frightening dreams, sleep as soundly as you can, forget your dreams and don’t allow them to influence your life!!!

8. Conclusion We can’t do without sleep. Young people need more sleep than elderly ones do (about 7.5 hours). No matter how much sleep you need: if you don’t get enough, you will suffer from the effects of sleep deprivation.
