Better out than in
Don't sweat over sweat... enjoy it!
To sweat is to cleanse; to rid your body of toxins; is to heal; is to cool the body down.
You are guaranteed to kick a looming lurgy if you just sweat a bit!
Get into a sauna, steam room, have a hot bath, go for a run, jump on the bike...
Yes yes yes - go to that Bikram class!
Back in the day when one had a cold or flu one would wrap oneself up in blankets to sleep and literally sweat the badness out.
Better out than in!
Don't forget sweat is your friend.
