Is this trial a fit for you?

Likely a good fit

Probably not a fit

Women without sleep disturbances, those unable to perform diaphragmatic breathing, or those with exclusions may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study will enroll women aged 25–35 with PCOS who have poor sleep quality and sleep-related symptoms. Participants will perform diaphragmatic breathing exercises along with lifestyle advice to see if sleep improves over time. Sleep quality and related symptoms will be assessed using standard scales such as the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Fatigue Severity Scale. The trial will exclude individuals with certain medical conditions or those currently using sleep medications to isolate the breathing intervention effects.

Why it matters

Potential benefit: If successful, participants may experience better sleep quality and reduced fatigue.

How similar studies have gone: Previous research suggests breathing exercises can improve sleep in various populations, but data specific to PCOS are limited, making this approach relatively novel in this group.
