NCT ID NCT05656768
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how sleep and your internal body clock influence blood pressure at night. Researchers will monitor over 1,400 participants using a constant routine protocol—staying awake in a dim room for over 24 hours—to measure melatonin, body temperature, and blood pressure. The goal is to better understand why nighttime blood pressure varies, which could lead to improved prevention or treatment of hypertension.

If successful, this could help explain why some people have high blood pressure at night and point to new ways to manage it.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test any therapy, and results may not lead to immediate changes in care.
