Nap duration during night shifts and blood pressure health

Official title: Effects of operational naps on blood pressure and performance among night shift workers

Funded at University of Pittsburgh at Pittsburgh · NIH-11508492 · Data updated 2026-11-12

A Phase II study will test how long night shift naps should be to restore normal blood pressure patterns and maintain safe performance, while considering caffeine use, for night workers.

Who could benefit from this research

Could help

Night shift workers, including healthcare workers and public safety personnel, who experience sleep disruption.

Less likely to help

Individuals who do not work night shifts or do not experience sleep-related BP changes may not benefit.

What this research studies

Night shift workers often have disrupted blood pressure dipping, which can raise cardiovascular risk. This study tests different nap lengths during night shifts to see which duration best restores normal BP dipping and minimizes lapses in psychomotor performance, all while tracking caffeine use. The research uses a crossover design to compare nap doses within the same participants, aiming to identify a safe and effective nap window. Results could guide workplace policies for healthcare workers and public safety personnel who rotate through night shifts.

Why it matters

Potential benefit: If successful, findings could lead to better nap guidelines that support heart health and safer performance for night workers.

How similar studies have gone: Previous data suggest short naps can impact BP and performance, but optimal duration in night workers needs confirmation in a controlled study.
