Swimming has become a standard sport in summer, and lying in a cold pool in summer is a great pleasure in summer! In addition to the comfort of cooling, swimming has several unknown benefits. Let’s take you to know about the benefits of swimming and related taboos today ~
Four benefits of swimming:
Step 1 lose weight
Swimming is one of the most effective ways to lose weight. Experts’ experiments show that the heat consumed by staying at 12 degrees Celsius for 4 minutes can only be consumed in 1 hour on land at the same temperature. The reason for such a big difference is that the density and heat transfer of water are greater than that of air, so regular exercise in water can gradually consume more fat and shape a more perfect posture.
2. It is beneficial to the recovery of chronic respiratory diseases.
Swimming can exercise the respiratory muscles such as pectoral muscle, diaphragm muscle and intercostal muscle, thus improving the ventilation function of the lungs and improving the efficiency of breathing. Proper swimming exercise is beneficial to the rehabilitation of patients with chronic respiratory diseases.
Step 3 strengthen your heart
As a horizontal exercise, swimming can not only make all parts of the body bear the same gravity, but also balance blood circulation and strengthen the heart.
Step 4 soothe joints
Different types of swimming movements can exercise the joints of the body. In addition, because the water has buoyancy when swimming, the legs are free from supporting the weight, and the main joints of the thighs can be relaxed and relieved.
Although swimming is good,But there are still a few points to pay attention to..
1. It is not advisable to swim for a long time.
The swimming duration should not exceed 1.5-2 hours. Because people stay in the water for a period of time, the blood flow on the body surface expands, and the skin turns from cold to warm. However, once they stay in the water for too long, the skin will gradually appear goose bumps and chills, which will have a certain impact on health.
2. It is not advisable to eat immediately after swimming.
Because swimming consumes a lot of fat and calories, there will be some hunger after swimming. However, eating immediately after swimming will increase the burden on the stomach and intestines, which will easily lead to gastrointestinal diseases for a long time. Therefore, you should rest for 1 hour before eating.
3. Patients with otitis media, dermatosis and acute conjunctivitis should avoid swimming.
There are a lot of bacteria in the swimming pool. If people with the above diseases swim again, it will not only make the original condition worse, but even spread the disease bacteria in the swimming pool, causing infection to others.
4. Pay attention to cleaning after swimming.
After swimming, you should take a bath or dry your body with a towel immediately, then drop Chlorella or boric acid eye drops on your glasses and clean up nasal secretions. If there is water in the ear, you should use "jumping on the same side" to discharge the water, so as to avoid the eardrum injury caused by hand digging.
