It's an honor to see your question and answer it for you.
I read an article not long ago, which is the so-called healthiest schedule. It says, "7: 30: Get up. Researchers in university of westminster, England, found that people who get up at 5: 22-7:2 1 in the morning have a high content of a substance that can cause heart disease, so getting up after 7:2 1 is more beneficial to their health. Turn on the light. Turn on the light as soon as you wake up, which will readjust your biological clock and adjust your sleep and wake-up patterns. Jim, a professor at the Sleep Research Center of Loughborough University? Horn said. Drink a glass of water. Water is the basic substance of thousands of chemical reactions in human body. Drinking a glass of water in the morning can supplement the lack of water at night. "
The article also mentioned the healthiest sleep time: "Sleep at 23:30. If you get up at 7: 30 in the morning, going to bed now can ensure that you enjoy 8 hours of adequate sleep. "
I have implemented it according to the schedule here, and it feels very general. I think this may be caused by individual differences. You mentioned that your biological clock is after six o'clock and after seven o'clock. I think this time is neither early nor late. If you can wake up naturally, it is also good to get up at this time.
As for the drug rehabilitation you mentioned, I have also read the relevant materials. Detoxification time is different in different parts of the body. For example, the liver, the best detoxification time is 1 am to 2 o'clock, while the heart is 1 noon1pm1pm.
Therefore, my suggestion is to plan the daily schedule reasonably according to my physical condition and biological clock. As long as you don't often stay up late and sleep late, you will have a good time.
