Chapter 3 Blog

From this chapter I learned about different levels of awareness, sleep, and other things that can effect the mind and the way it works. The levels of awareness affects me because it is important that I know what level of awareness I am at and know what I am doing. Sleep of course has a huge affect on me, and it has shown me how sleep is affected by cycles and the brain. It has also shown me how important sleep really is to us. People are on a kind of biological clock, it can be thrown off easily, but it is important that people are able to be on schedule with their biological clock. Sleep can affect happiness, concentration, slower reactions and thinking time, and many other functions necessary to people. Something I found surprising was how active the brain really is when we sleep. Most people assume that when we go to sleep, everything just kind of shuts down. This chapter showed that our brain is sending out different waves at different amplitude and frequency. There's really nothing I disagree with in the chapter, it all makes sense to me.
