Traveling to Lijiang, I now have symptoms such as nausea, vomiting, bloating and general weakness. How can I relieve this disease?

I come from Lijiang. Lijiang has strong ultraviolet rays, low air pressure and thin air at this season. Stay out for a long time, so it is when you go home. Don't bask in the sun, even if your back is to the sun. Eat more fruits. It is best to get up in the morning and go for a walk outside. Don't eat chocolate or anything like that. Strenuous exercise will only aggravate your reaction.
