How can I improve my immunity? It's best to eat and exercise, I get colds when it's windy and I can't get better, I have to be on the computer all day!

To go out and exercise more! And drink some bone broth! That's what I usually do! You can also try toad oil from wild female forest frogs in the Changbai Mountains! Medical research has found that toad oil has the effect of enhancing immune function, anti-fatigue, lowering blood lipids, nourishing skin, and slowing down the aging process, which is a good tonic for the human body. And it is also the wild forest frog oil in Changbai Mountain! The nutritional value is quite high!
