Likewise, to keep its balance, your body needs proper amounts and types of
nutrition, rest, movement, fresh air, and
warmth. Too much of
anything (including food, exercise, and heat) and the wrong types of things (such as polluted air, junk food, and dangerous drugs) also cause stress.
If a physical stress is short term, like missing some sleep on exam night or having an occasional ice cream, the body can usually recover.
