Virtual reality glass: Virtual reality (VR), with its immersion and interactivity, offers the possibility to amplify the effectiveness of breathing techniques in promoting mental health by creation of relaxing scenarios and has been successfully employed in promoting relaxation and stress reduction. Virtual reality can turn breathing exercises into an interactive experience that feels more like a fun activity than a tedious task. It consists of VR headset, two touch controllers, glasses spacer with adjustable straps for good vision as follows:
1. Colour Breathing VR program (Box Breathing) :
Patient sit in comfortable position with relaxed both shoulders. Breath in for 4 second, Hold breath for 4 sec, Breath out for 4 sec, Hold for 4 sec, Inhalations and exhalations move a 3D cloud shaped object closer and farther away from the user.
2. LAMINAL VR (Calm): Inhalations and exhalations grow and shrink a 2D circle with bubbles in between, changing in color.
Buteyko Breathing: 1. The ''Control pause (CP)'' breathing test: Hold his nose on the "out" breath, with empty lungs but not too empty and count how many seconds that he can comfortably last before the need to breathe in again.
2. Shallow breathing Sit up straight: breathe air slightly into the tip of the nostrils. Concentrate on calming his breath to reduce the amount of warm air he feel on his finger, try to maintain the need for air for about 4 min.
3. Putting it together Take Control pause:
Reduced breathing for 4 min. Wait 2 min and take Control pause. Reduced breathing for 4 min. Wait 2 min and take Control pause.

Primary outcome measure(s)
Control pause breathing test — 8 weeks It is part of the Buteyko method of breathing exercises and is designed to measure the length of time a person can comfortably hold their breath after a normal exhalation. its normal range is between 0-60 seconds, less than 20 seconds means poor control.
Asthma control test — 8 weeks It was a commonly valuable tool to assess asthma control that typically involves a self-reported questionnaire that evaluates symptoms over the past 4 weeks. It is self reported 5-25 scale. Higher score indicates better control. less than 16 indicates uncolntrolled asthma
Forced Expiratory Volume in one second (FEV1) — 8 weeks FEV1 stands for Forced Expiratory Volume in 1 second. It is a measurement taken during a spirometry test, which assesses lung function. Specifically, it measures the amount of air a person can forcefully exhale in the first second of a forced exhalation. A lower FEV1 reading can indicate an obstruction in the airways, potentially pointing to conditions like asthma. Normal values for % predicted FEV1 are generally 80% or higher of the predicted value. 60-80%moderate, \<60% severe.
Forced vital capacity (FVC) — 8 weeks Forced vital capacity (FVC) is the maximum amount of air a person can exhale after taking the deepest possible breath. It's a key measurement in spirometry, a common breathing test used to assess lung function. FVC helps doctors identify and distinguish between different types of lung diseases, including obstructive (like asthma). FVC can also be expressed as a percentage of the predicted value, with 80% to 120% considered within the normal range
FEV1/FVC ratio — 8 weeks The FEV1/FVC ratio is a calculation used in pulmonary function tests, specifically spirometry, to assess lung function. It represents the proportion of a person's forced vital capacity (FVC) that they can exhale in the first second of a forced expiration, known as forced expiratory volume in 1 second (FEV1). A normal FEV1/FVC ratio is typically above 70% (0.75-0.80), and a lower ratio suggests an airway obstruction
Peak expiratory flow (% predicted) — 8 weeks It refers to the percentage of a person's measured PEF compared to their predicted PEF, based on factors like age, sex, and height. It's a way to assess how well someone is breathing compared to what's expected for them, with lower percentages often indicating airflow obstruction such as asthma. PEF predicted % is calculated by dividing the actual PEF measurement by the predicted PEF and multiplying by 100.
A lower PEF predicted % generally indicates a greater degree of airflow obstruction.
For example, in asthma, a PEF predicted % below 50% may indicate a severe exacerbation.
Anxiety level by Hospital Anxiety and Depression Scale (HADS) — 8 weeks It is a 14-item questionnaire that assesses anxiety and depression symptoms for all participants before and after the treatment program. It has two seven-item subscales, one for anxiety and one for depression. Each item is scored on a 4-point scale, with a maximum score of 21 for each subscale. Scores are categorized as normal (0-7), mild (8-10), moderate (11-14), and severe (15-21) for both anxiety and depression.
