Chapter 3 Blog

After reading this chapter I was really astounded by how important sleep is for our bodies. Its because of sleep that we can recover physically and mentally. It helps repair damaged cells and refreshes the body and also repairs our brain and prepares it for the next day. This chapter made me question whether or not we can live without sleep. I've heard that it is impossible to go more than three days without any sleep. Unless people suffer from night terrors or some other psychological disease. Another thing I learned from the chapter was all the sleep disorders that can affect us and what they can do to our brains and ourselves. The last thing I learned was all the cycles that our sleep goes though. I had heard about REM sleep but never knew it was so crucial for our survival.
