In terms of clothes: what clothes to wear in what season (provided that you need to watch the weather forecast every day)

In terms of food:

The simplest: eat less "fat" and eat something light in short.

Advanced edition: making tea (medlar, chrysanthemum, bitter buckwheat, etc. )

Extreme edition: medicated diet (it is recommended to find a professional, such as consulting an old Chinese doctor)

From the aspect of life: it is good to live happily.

From the aspect of travel: it is difficult for anyone to eat enough after walking for a long time. It is suggested that several people go out for a ride when they are free (not necessarily a formal ride, just a small bike)
