Swimming is a complete and beneficial sport of Lifeguard course near me for the health of thousands of people. However, when it comes to individuals with chronic asthma, there is a paradox among researchers in the field: while swimming is believed to help asthmatics breathe. It is also known that the high levels of chlorine in swimming pools can be irritating to the airways of these people.
Asthma: what it is and what is its incidence in Brazil
Asthma is a chronic disease that affects the airways or bronchi, organs responsible for transporting air to the lungs. According to data from the Unified Health System (DATASUS) , in Brazil, approximately 350,000 hospitalizations per year are caused by asthma.
This is a dangerous condition as asthma behaves like an inflammatory lung disorder. Therefore, by inflaming the airways, they temporarily narrow and make it difficult for the individual to breathe.
This pathology is responsible for 2.3% of hospitalizations. In the Unified Health System (SUS) and can affect both children and adults. It is even a common disease that starts in childhood. It is estimated that there are about 20 million Brazilians with lifeguard course near me this disease in the country.
Swimming with lifeguard course near me is considered, by sport experts , one of the most complete modalities to be practiced. In addition to moving the upper and lower limbs of the body. This practice has a low level of impact, that is, it has a lower risk of causing injuries to your athletes. Also, this is an effective exercise for weight loss , since it has a high caloric expenditure. Reaching up to 700 calories per hour of swimming.
Benefits of swimming for asthmatics
There are numerous benefits of swimming for asthmatic individuals. Since this activity induces bronchoconstriction in a less severe way than other physical exercise modalities. This swimming effect is thought to possibly result from the high humidity of the air inspired by the water level. Due to the high level of humidity. This reduces water loss through respiration and can decrease the osmolarity of the mucus in the airways.
Furthermore, swimming is practiced in a horizontal position, which is positive for the asthmatic athlete. As it influences the individual’s respiratory route and results in lower airway resistance. Therefore, due to this combination of factors, swimming is commonly indicated for asthmatics. Swimming regularly proves to be a safe and pleasant practice to maintain lung function. Increase aerobic capacity and improve the practitioner’s quality of life.
Risks of swimming for asthmatics
However, there are theories that claim the opposite of what was previously reported. Swimming can worsen the condition of individuals with chronic asthma. Noting the worsening respiratory health of swimmers, the researchers’ current hypothesis is that chemicals found in swimming pools. Such as chlorine and its by-products, have an irritating effect on athletes’ airways.
Therefore, this irritability makes them more sensitive to environmental stressors, such as allergens or infectious agents. This statement is based on biomarker studies that demonstrate that “chloroforming products can cause chronic or acute disruption of the epithelial barriers of the lungs”. As referenced by data from the scientific article by Bernard A, Asthma and Swimming with lifeguard course near me. Weighing the benefits and risks ( Asthma and swimming: weighing the benefits and the risks. J Pediatric Rio J ).
So while there is evidence that chlorine used to clean pools is harmful to asthmatics. Swimming is indicated to relieve swimmers’ airways. Therefore, this relationship is in a paradox. There are those who compare this situation with “the chicken and the egg”. Without understanding who came first and who comes later.
Thus, up to this point, one can only recommend asthmatic swimmers to avoid poorly managed pools. With excessive levels of chlorine in the air or water. So, to identify pools in these conditions, it is important to pay attention to the strong smell of chlorine in the environment and even the irritating effects on the skin. Eyes or airways in contact with the water and environment of the pool.
Always remember to consult your doctor and experts in the field if you experience any discomfort or discomfort. Also, for the best effectiveness of your practice, always be guided by a physical education teacher, physiotherapist or qualified professional.
