Long-term swimming exercise can bring six benefits to the body, but swimming is not recommended in these four situations.

As the weather gets warmer and warmer, many people begin to swim in the swimming pool. Swimming is a good aerobic exercise, which can exercise the muscles of the whole body without increasing the load on the knee joint. At the same time, it can also protect the cardiovascular system and increase the cardiopulmonary function. Let’s take a concrete look at the benefits of regular swimming.

1, limbs get exercise

When swimming, use the strength of limbs to promote the body to move forward, and the waist and abdomen muscles maintain the swimming posture. Therefore, swimming can exercise multiple muscles of the whole body, help shape the body and increase the proportion of muscle tissue.

2. Help to lose weight

Swimming can consume calories better, and the calories consumed by swimming for 60 minutes can reach 400~700 calories. At the same time, the waist, buttocks and limbs can be exercised, which can achieve the effect of losing weight.

3. Improve vital capacity

When swimming, the breathing frequency is matched with the movement, so that each breath is lengthened, the elasticity of lung tissue is increased over time, the vital capacity is expanded, and the risk of lung diseases is reduced.

4. Improve immunity

Stimulated by cold water, the body can easily adapt to temperature changes, improve immune regulation and enhance resistance.

5. Improve memory

Studies have shown that swimming can increase blood flow to the brain, benefit brain health, maintain memory and delay Alzheimer’s disease.

6. Adjuvant treatment of constipation

Sticking to swimming can speed up the peristalsis of gastrointestinal tract and help alleviate problems such as abdominal distension and constipation.

1. Patients with ear diseases

People with tympanic membrane perforation can’t swim, so as to avoid water flowing into the middle ear cavity through the perforation, which will lead to acute otitis media; Deaf people can’t swim either, because the organ that regulates balance in the ear has been damaged, and the balance force is weakened, and drowning may occur when swimming.

2, after drinking, fasting and full.

Alcohol can inhibit the central nervous system and weaken the contractility of the heart. Vomiting, nausea and dizziness may occur after drinking. In addition, drinking can promote systemic vasodilation, lead to a drop in body temperature, and promote energy consumption, and swimming after drinking may cause drowning risk. You can’t swim immediately after a full meal, so as not to affect digestion and lead to indigestion, vomiting or abdominal pain. You can’t swim on an empty stomach, otherwise it will reduce your appetite and weaken your digestive function; It is prone to hypoglycemia and may even drown because of dizziness and fatigue.

3. People suffering from infectious diseases

You can’t swim when you have emphysema, tinea corporis, conjunctivitis or trachoma, as well as liver disease and highly contagious skin diseases, otherwise your condition will worsen. In addition, you can’t swim when your skin is damaged, so as not to cause infection.

4. Patients with severe heart disease and hypertension

When swimming, the heart bears a heavy load and the oxygen consumption of the whole body increases. Patients with heart disease may not be able to provide enough blood because of insufficient myocardial contraction, and may faint when swimming, thus causing accidents. In addition, patients with hypertension have weak vascular elasticity, and dizziness and angina pectoris may occur during swimming.

Tips

In addition to the above groups, women with gynecological diseases should also be cautious. Due to poor physiological condition and weak immunity, forced swimming will make bacteria invade the vagina, thus inducing or aggravating gynecological diseases; Women who are in menstrual period, pregnancy and lactation should try not to swim. In addition, there are 5 to 10 minutes of warm-up before each swimming, such as jumping or running in place, which can prevent cramps during swimming. At the same time, control the swimming time, which cannot exceed 120 minutes.
