| Just some personal observations here. I have read that most software breakthroughs occur around 1:00 AM and have found this to be true in my personal experience. In the military I worked in a shop which was manned 24/7. Normally the shifts were 8:00 AM - 4:00 PM, 4:00 PM - midnight, and midnight - 8:00 AM. One month they changed to two shifts, 8:00 AM - 8:00 PM and 8:00 PM - 8:00 AM. The next month they moved everybody to the other shift. I worked each of the 3 normal shifts for several months each. For me the most difficult was midnight - 8:00 AM because of the difficulty sleeping in the daytime in a noisy barracks. I found that for me the best way to cope with this was to work a shift, stay up all day, and work another shift, after which I would sleep for 12 hours. In civilian life I worked normal 8-5 jobs and it has always been difficult for me to get to sleep and wake up early. One time I worked a normal shift, worked through the night with no interruptions, and worked the next shift. I was able to accomplish more in that time than I normally would have in two weeks. Now that I am retired I go to sleep when I am tired and get up when I wake. There is no discernible pattern to it. It is much easier to stay up later than it is to get to sleep earlier. The easiest way to adjust to a new sleep pattern is to stay up later, delaying sleep until it has moved to the desired time. You can move it by two to four hours a night this way. Trying to sleep earlier you can only alter your sleep cycle by about half an hour a night. |
