In the article, “Why swimming is so good for you”, Markham Heid discusses the reasons why swimming is the best aerobic and cardio-vascular exercise (http://time.com/4688623/swimming-pool-health-benefits/) The commentary proves to be a helpful resource by making people aware that swimming has proved to be good for the heart. Without the resistance of gravity, every muscle in the body is working to keep your body healthy while you are swimming. It also helps your breathing by strengthening the respiratory muscles. Heid discusses how a regular swim can help people with arthritis and decrease tightening of the arteries to prevent heart attacks. People with hypertension can lower their blood pressure with a regular swim schedule.
The buoyant quality of floating can help overweight people exercise without as much exertion as regular aerobic exercise. Breathing is also improved when swimming. Unlike running where short, shallow breaths are taken, swimming requires deep breaths released slower, strengthening lung capacity. The lung alveoli become stronger and do not stick together as much. In addition, swimming is a great way to keep the body toned, because all the muscles are used.
Both the lower and upper body are working when swimming, as opposed to running or biking where there is mostly lower body exertion. The benefits to the lower back are also evident, because exercising horizontally counters the constant bending of the back that hampers people who work at a desk. Swimming also helps maintain healthy posture. Thirty minutes of swimming a day is all it takes.
