It causes recurrent episodes of wheezing, dyspnea (difficulty breathing), chest tightness and coughing, particularly at night or early in the morning. These symptoms are usually associated with an obstruction widespread, but variable, airway, which is reversible either spontaneously or through treatment.
The physical activity is viewed with some caution by some health professionals, but when properly oriented is beneficial to patients with the disease, since these exercises help in correcting the posture, improvement of respiratory mechanics, and the effectiveness of ventilation, facilitating the passage of air, respiratory keeping everything in good condition and causing the individual create more resistance, providing reserves to withstand the crisis.
The physical activity also prevents asthma to reduce the possibility of a crisis, there are some tricks, as a good warm up (which should be of low intensity at the beginning) and an adequate relaxation after exercise, the adaptation of the duration and intensity of exercise on the severity of the particular case, and the avoidance of allergens and protection from the cold. You always have to breathe through your nose, so that the air maintains a high moisture content before entering the airways. It is also recommended before exercise to avoid the suspicion or diagnosis of a respiratory infection.
Be careful and avoid too intense activities. Asthma can also be induced by exercise, resulting in an asthma attack (coughing, wheezing or chest feeling “tight”). Over 80% of people with asthma may manifest these symptoms during or after exercise. Generally, symptoms appear shortly after the onset of physical activity and worsen in 15 minutes later. Wich should stop immediately the practice of the physical exercise.
Activities that involve short periods, such as volleyball, gymnastics and baseball are generally well tolerated by people with asthma. The exercises with long periods such as soccer, basketball, jogging should be avoided. Although swimming is a sport of strong resistance, it can also be practiced by most asthmatics.
