Ah, a relaxing time after classI feel like eating ice cream today
It was a good ice cream but I don't think I felt good
By now my mom said I have a cold, I should stay in bed to recuperate
After the rest I feel so much better now

The body will become cold resulting from the virus, the body will generate more heat which worsen the condition, thinking the heat will help solve the cold. Which is the positive feedback that the body given to you.

Other system may help to the minority of like circulatory where it help pumping blood. All of this is called homeostasis where the body is trying to maintain balance as explained in the previous lessons.
