【英语时差8,16】生病了也可以运动？

D: I guess it make sense. It's just I've heard that regular physical activity can strengthen your immune¹ system and help prevent catching² cold and other illnesses. So I figured that even if you’re already sick, doing something physical may help. Y: Well,again it might.But it depends on how sick you are.In some cases, like if you have a fever, working out can tax their body and make the illness worse.So you need rest to regain³ strength. And when they’re coming out of a really bad cold or fever, it’s best to ease back into exercise instead of jumping right back in. D: Thanks for the advise. I'm gonna take my tempreture. Y: Good idea.
