Swimming and its effects on our health
Numerous studies have shown that light-intensity swimming has positive impact on high blood pressure. Light swimming for four or five times a week for about half an hour or three times a week for 20 minutes is ideal for persons dealing with hypertension.
On the other hand, a large number of people, especially young people, have problems with low blood pressure, which is almost harmless, but it can create a lot of inconveniences. Regular moderate swimming can strengthen the blood vessels and deep breathing provides extra oxygen to all the cells in the body. The massage effects created by the resistance of water and improved circulation also eliminated the inconveniences caused by low blood pressure.
A large number of people suffering from asthma experience attacks during exercise and this is a situation which experts describe as exercise-induced asthma. The characteristics of these attacks depend on the intensity of training, the need for air and the specific environmental conditions, making swimming the perfect choice. The breathing technique in the water strengthens the muscles that allow exhaling.
Everyday sedentary lifestyle causes many problems in the spine. Some of these problems are caused by bad posture while others are conditioned by certain defined deformation of the spine like kyphosis, lordosis and scoliosis. According to some stats, 9 in 10 people experience back pain in acure or chronic form and that’s why instructors recommend backstroke style. Butterfly and breaststroke are not recommended because of the large movements in some parts of the spine as well as the position of the neck and head during swimming.
Swimming has a positive effect on physical, mental and social development in children because just like many other sports it involves social contact and companionship. The water is ideal for children because it allows freedom of movement and a sense of lightness which is very important for young children. In addition, swimming allows proper developing of basic motor skills and contributes to the overall development of children. It is especially useful for the lungs and heart. Besides that, swimming has a positive impact on sleep, immunity and the ability of thermoregulation.
Recreational swimming is very effective for the older people too because exercise in old age often has specific limitations and swimming doesn’t come with any contraindications. In other words, people can swim regardless of their age. Swimming makes the heart muscle stronger and because of this muscle strengthening property, swimming also improves breathing, so the cells in the body get more oxygen which is extremely important for the elderly.
In people who have a body mass index higher than 25 or 30, water sports are perfect for reducing body weight. Most of the other physical activities produce great load on the joints. When it comes to swimming, the body temporarily loses its actual weight and the load is significantly reduced. With regard to the density and resistance of water, it is not surprise that people are able to spend large amounts of energy in a short period of time.
