Unit 6

In this unit we learned about different ways there are to learn and the 5 stages of consciousness. one of them being sleep. the stages of sleep being:

·         Stage 1-kind of awake and kind of asleep , only lasts a few minutes and you usually only experience it once a night, brain produces theta waves

·         Stage2- this follows stage 1 sleep and is the baseline of sleep, this stage is part of the 90 minute cycle and occupies approximately 45- 60 % of sleep, more than theta waves, slow sleep spindles= short burst of rapid brain waves

·         Stage 3 and 4- slow wave sleep, you produce delta waves, viral for restoring the body’s growth hormones

·         Stage 5- REM sleep- rapid eye movement, brain is very active, drams usually occur, body is paralyzed, from REM you go back to stage 2

This video goes into the five stages and what you feel during the five stages:

 

The following video goes into a sleep disorder, insomnia,  where a person has continued difficulties going to sleep. this video goes into how insomnia is diagnosed and even how it is treated.

I enjoyed this unit, because I have always been very interested in dreams and what the body experiences while asleep one of the most interesting stages to me is REM sleep. Which is when dreams usually occur and the body becomes paralyzed so that the body does not act out the dream. I always wondered how this worked and now thanks to this unit I do.
