1 Inha University Unit 3 Public Health: Sleep

2 In today’s class we are going to look at how sleep disorders affect people.

3 One of my favorite sleep disorders is sleep paralysis. In Korean it is known as Gawee Nulim.

4 The scientific explanation of sleep paralysis is simple: (1) Your brain goes into REM sleep. (2) Your body chemically shuts down your muscles so that you don’t move while you are dreaming. (3) You wake up in the middle of an REM cycle and your muscle and brains are still disconnected.

5 Simple enough. But what’s interesting is that most people who experience this feel an evil presence in the room when this happens. Many people in fact claim to see a dark shape behind them when it happens. Nobody ever reports a positive feeling or presence when this happens.

6 In cultures all around the world, people attribute this dark presence to be a demon, ghost or evil spirit that presses on a persons chest and steals their breath. In Korea, for example, it’s a ghost. In Turkey, it’s a Djinni. In Eastern Canada it’s an old hag (evil witch).

7 In hundreds of cultures around the world people report spirits, demons, creatures, goblins, succubi and ghosts sitting on people and strangling them.

13 Last class, I asked you to write a summary paragraph on the characteristics of happy people.

14 Topic The lecturer discusses the common characteristics of happy people. Psychologists have examined the characteristics of happy people. The lecture covered the characteristics of happy people.

15 Supporting Sentence + Details One important characteristic of happy people is family and friends. Studies have shown that happy people tend to have strong connections with family and friends and make time to spend with them.

16 Supporting Sentence + Details Another characteristic of happy people is religious beliefs. Believing in something bigger than themselves helps people find meaning in their lives.

17 Supporting Sentence + Details Setting goals is a third characteristic of happy people. Happy people tend to establish goals for themselves in their work and personal lives around things that are interesting or use their strengths.

18 Supporting Sentence + Details Surprisingly, having lots of money is not a characteristic of happy people. As long as someone has enough money to provide the essentials for life, having more money did not bring extra happiness.

19 Supporting Sentence + Details High education is also not a characteristic of happy people. Studies have shown that people with low education are just as happy as people with high education.

20 Supporting Sentence + Details Finally, youth is another feature that was not a characteristic of happy people. In fact, research has shown just the opposite, that people aged years old tended to be happier than people aged

21 In short, there are characteristics of happy people that can be identified, but they are not always the characteristics that you might guess.
