Problem analysis: Hello, you can't rub your navel often, but just rub it properly. Generally, you put your palm on your navel and gently rub it counterclockwise and clockwise four times a day. Long-term persistence plays a great role in increasing gastrointestinal peristalsis, enhancing spleen and stomach function and promoting digestion.

Opinions and suggestions: everything has its limits, and excess will only be harmful. I suggest you don't rub it often, just stick to a proper massage every day, which can promote digestion. I hope it helps you, and I wish you good health.
