Why is it said that staying up late regularly can worsen your luck?

Because the night itself is the time for cultivating righteousness and restoring our spiritual energy.

When we sleep, our spirit is more easily able to return to our body.

If you don't rest at this time, your mind and spirit are still wandering outside.

The spirit and mind can be understood as the guardians within our body.

If the guardians are often unable to enter, then uninvited guests will come in.

When uninvited things enter your body, you will develop some虚病 (subtle illnesses).

This illness seriously affects your spirit, your ability to judge things accurately, and your health.

Think about it—would your luck be good?

Therefore, if you want to change your fortune, you need to understand health preservation, and the most basic aspect of health preservation is to go to bed early and get up early.
