When a person exercises, his or her body responds in a variety of ways, according to the Huffington Post. The publication explains that exercise not only helps physical development but also plays an important role in assisting the body in ensuring a person’s mental and emotional health.

According to the Huffington Post, exercise compels the body to operate at heightened levels that strengthen it. The publication explains that a person’s heart begins to immediately beat faster to pump more blood to muscles, tissues and organs during exercise. Blood vessels widen in an effort to enhance circulation throughout the body, while the lungs expand and contract faster, and more deeply, absorbing more oxygen and releasing more carbon dioxide. The working muscles, as the piece states, burn more energy to fuel their contractions helping to develop their strength and resistance.

The increased blood flow that occurs during exercise regimens helps the brain as well, states the article. Brain cells begin immediately to operate at a higher level making a person feel more alert and focused. According to the publication, this helps protect people from diseases like Alzheimer’s and Parkinson’s as well as helping to elevate their emotional mood as a buffer against the onset of depression.
