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.
