This is a two-arm, double-blind, randomized controlled clinical trial. The randomization list of participants will be generated by an online program (www.random.org). The blind allocation will be carr
2nd moment, after 4 weeks of the beginning of the intervention
3rd moment, after 8 weeks, at the end of the intervention. 50 patients will be included in the trial. 25 intervention group will perform diaphragmatic breathing. This is a breathing exercise in which
Place your hands on your abdomen near your navel Inhale through your nose slowly and deeply, expanding your abdomen that can be felt by your hands
pause for 2 to 3 seconds. Exhale slowly through your mouth, completely emptying your abdomen. The teaching and training of the diaphragmatic breathing technique will be given by a duly trained health

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main primary outcome of the study will be asthma control, determined through a validated questionnaire - the Asthma Control Test (ACT) ;Assess anxiety levels. Anxiety symptoms in children and adolescents will be assessed using the Spence Children's Anxiety Scale -SCAS. ;Assess basal cortisol levels by quantifying cortisol levels in salivary samples.;The severity of the airflow obstruction will be evaluated through the peak flow test, which will provide us with the forced expiratory volume.;Autonomic modulation will be evaluated through analysis of heart rate variability (HRV). Low frequency (LF = 0.04 to 0.15 Hz) and high frequency (HF = 0.15 to 0.40 Hz) spectral components expressed in normalized units (nu) are used, as well as the LF/ HF in milliseconds squared (ms²). The autonomic balance will be assessed by analyzing the HRV collected through the blood volume pulse (BVP) collected at rest and in the lying position during breathing exercise. | — |
