Is this trial a fit for you?
✓Likely a good fit
Adults with mild to severe OSA who have started CPAP within the last year and use it regularly, plus those with habitual snoring, without recent participation in OSA-focused physiotherapy.
✕Probably not a fit
Individuals with BMI over 40 kg/m² or significant comorbidities that limit physical activity may not experience demonstrated benefits from this intervention.

What this trial studies
This interventional study explores how habitual daily physical activity relates to sleep quality and respiratory parameters in adults with obstructive sleep apnea. Participants are individuals with mild to severe OSA who recently started CPAP and regularly use it, and who have habitual snoring. The study involves physical activity education as the intervention, aiming to see how increasing daily activity may influence sleep and respiratory outcomes. Exclusion criteria include high BMI, certain medical conditions, and medications that could affect sleep, to ensure participant safety. The trial is conducted at Istanbul Medipol University in Istanbul, Turkey, led by Medipol University with no listed collaborators.
Why it matters
Potential benefit: If successful, participants may experience improved sleep quality and better respiratory function through more favorable daily activity habits.
How similar studies have gone: Previous research suggests physical activity can improve OSA-related symptoms and sleep quality, but evidence on habitual daily activity patterns remains limited.

Inclusion Criteria: * Individuals diagnosed with mild to severe obstructive sleep apnea (OSA) based on laboratory polysomnography (AHI: 5-30 events/hour). * Individuals diagnosed by a pulmonologist within the past year who initiated CPAP therapy no more than 12 months ago and demonstrate regular use. * Individuals with habitual snoring. * Individuals who have not participated in OSA-focused physiotherapy interventions within the past 3 months. Exclusion Criteria: * Body mass index (BMI) \>40 kg/m². * Severe substance or alcohol dependence. * Regular use of sedatives, muscle relaxants, or opioids that may affect sleep patterns. * Pregnancy or postpartum period (\<6 months). * Medical contraindications to physical activity according to American College of Sports Medicine (ACSM) guidelines, such as unstable coronary artery disease or decompensated heart failure. * History of stroke or significant respiratory, neuromuscular, inflammatory, or other disorders causing hypercapnia. * Craniofacial abnormalities, severe upper airway obstruction, or secondary respiratory diseases such as chronic obstructive pulmonary disease (COPD).
