Old people often say that there are "three things to sleep, three things to do and three things to eat" in autumn. What the hell does that mean?

After washing your hair, you can't go to bed until it is dry;

Don't stay up too late, and don't stay up late to play at night;

Can't sleep on the ground, it's wet.

Three don't do:

Don't take a cold bath;

Don't overeat;

Do not do strenuous exercise;

Third, eat:

Warm food: mutton, pepper, etc.

Eat dampness-removing food in autumn to pave the way for winter;

Dandelion can diminish inflammation and dispel fire.
