Buddhist scriptures should be treated separately from life and even health preservation. I think you're asking about routines in life.

1, there is only one iron law of life and health-health.

How to adapt? Sleep at dark and do it at sunrise. Sleep time is determined by the length of day and night in four seasons, such as going to bed early and getting up late in winter, staying up late and getting up early in summer and so on. (See Huangdi Neijing for details. )

However, the hematopoiesis time of human body is from dark to 1: 40 (local time), so it is beneficial to sleep before 1 1: 00 at night.

2. Buddhist scriptures do not take health care as the first element, advocate less sleep and more practice, and don't eat in the middle (as long as you eat a meal before noon a day, you won't eat after noon. )。 We can also see the lifestyle advocated by the Buddha from the daily life of the Buddha recorded in Agama.

Everything is like a dream.
