Weighted blankets put to the test for ADHD Kids' sleepless nights
NCT ID NCT07588659
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study looks at whether a store-bought weighted blanket can help children aged 5-12 with ADHD who have trouble sleeping. 100 kids will use the blanket every night for 4 weeks, and researchers will track their sleep with a wrist monitor. The goal is to see if the blanket increases total sleep time and helps them fall asleep faster.
