First notebook entry: Wake up my life! WAKE UP MY LIFE! I cannot believe that is true! I was doing an interesting study on our sleep. It was just a verification experiment. During the first night of the experiment, I woke up three times. I insisted a strong thought that I must woke myself before four o’clock on that next morning, which lead to the result that I naturally awake respectively at 2:00, 4:00 and 5:30. This time I fall asleep at 23 p.m., which I cost six hours and a half on my sleep. And things went similarly to the first night. I still fall asleep at 23 p.m., but a slight difference happened to me that I only woke up two times. Thus, also at 4:00 and past 5:30. I was amazed at the easiness when I got up. Last week I was sufferring in feeling hard to get up every morning, when I slept during 23 p.m. to 6 a.m.. Now I know the very problem is just the extra 30 minutes I overslept. I become aware of my sleep duration on my bed. Doctor Kacper M. Postawski said there are sleep circles happens multiply in the duration of people’s sleep and each one of these circles takes about 60 to 100 minutes. We can divide the whole duration into 6 or 7 segments and the more close to dawn the more time Rapid Eye Movement sleep takes up.In other words, the less time deep sleep we can enjoy and we are more likely to wake up. That’s just the reason of that people are more likely to wake up on the morning. So now I can WAKE UP MY LIFE! To work hard during others’ sleep, we can easily get up at 5:30 or even 4:00 to do some reading,listenning and jogging I like. And because of the uselessness fill in the too much circles in our sleep, we can definitely abandon them and it has little impact on the active and efficient work during the day.
