Can a good Night's sleep tame asthma in urban children?
NCT ID NCT05420766
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 2 times
Summary
This study looks at how changing sleep time affects the immune system and breathing in urban children with asthma. Researchers will ask some children to go to bed 90 minutes later for a week, while others keep their usual bedtime. They aim to understand if short sleep worsens asthma and if catching up on sleep helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could reveal how sleep changes affect asthma control, pointing toward better sleep-based management strategies.
- What could go wrong
- This is an observational/behavioral study, not testing a new drug. Results may not lead to immediate treatments, and individual responses to sleep changes vary.
