(Q004) Jamie tells her doctor that she has been feeling a little down lately. The doctor responds by saying, "I think you should start exercising. Research finds that people can improve their mood and help them feel stronger and healthier by exercising for as little as minutes a day."

"... Research finds that people can improve their mood and help them feel stronger and healthier by exercising for as little as 10 (ten) minutes a day."

Explanation:

Researchers have found that exercising for as little as 10 minutes a day can be enough to improve our mood. Exercising releases endorphins, a type of "feel-good" chemical that helps reduce anxiety and depression. We feel more energized physically and mentally by exercising even if not for a long period of time. As a matter of fact, while 10 minutes a day are enough to improve our mood drastically, there is a ceiling as to how much better we can feel. Research has shown that exercising for many hours a week does not make a difference in happiness levels.
