How to stay healthy when traveling occasionally, staying in hotels and eating out?

My situation is similar to yours. My experience is that, first of all, you must have a good physical foundation to adapt to the changing living environment when you are on a business trip. Secondly, let work and life be as close to the original rhythm as possible after the business trip; Finally, drink more water and eat more fruits to prevent excessive internal heat and indigestion. When eating out, eating garlic and vinegar helps to disinfect. It is recommended to take some health care products that can quickly help improve immunity, such as Echinacea from Amway.
