By changing our time to "daylight" time, we were helped to go to bed earlier which is what we need to do. The hours of sleep before midnight are more valuable. This is what ought to be instructed to people. When we were told it was 10pm, it was only 9pm. So, unknowingly the world helped us to go to be earlier which helped us greatly to experience better lives.
Now the clock goes the other way. When we go to bed at 9pm, it is really 9pm. Don't stay up until 10pm.
It is always a blessing to fly east. When we cross time zones, I try very hard to stay on "my" time zone. This makes it very easy to go to bed early. So early that I have to be careful to not get up too early.
Follow this: West Coast time is 7pm. East Coast time is 10pm. My fellow workers are going to bed at 10 or 11pm. I am going to bed at 7 or 8pm.
My friends are getting up at 7am, I am getting up not at 4am, but at 2am. It makes it very easy when the sun is going down earlier than it would on the West Coast and the whole world around me is going to bed at 7pm my time!!!
Another benefit of not going off of West Coast time? No jet lag!! None at all. Care must be taken to not get up too early. It would not be hard to get up at midnight if I went to bed at 7pm. That would make the work day, 19 hours. But, the truth of the matter is that the hours of sleep before midnight are more valuable and the earlier we go to bed, the less sleep we need. This does not take into account those who are ill or are not living healthy lives. Eating wrong will create sleep problems that will offset the early to bed early to rise law of life.
For any who are having sleep problems, quit eating in the evening. Make your last meal in the afternoon. See if this does not improve the quality of your sleep. The body takes quite awhile to digest food. A late meal of cow or pig will take even longer to digest. The body is working hard and the mind is even effected so that the sleep is disrupted. Try it and let us know how it works for you.
