Answer:
The correct answer would be, When you are recovering from common illness.
Step-by-step explanation:
It is good to be in positive energy balance when you are recovering from common illness.
There are two types of energies in a human body. One is positive energy and the other is negative energy. Energy balance is concerned with the activities of the cells in a human body, like what is going in or what is coming out of the cells. When a person is in positive energy balance, more energy is coming in the cells than going out of them. Similarly in negative energy balance, more energy is going out of the cells than coming in them. So when a person is recovering from the minor illness like flu, cold, cough, Positive energy balance plays an important role as it takes in more good energy into the cells than releasing the energy from the body which might be required by the body at the time of recovering from the illness.
