Acute Muscle Pain and Sleep in Insomnia vs. Healthy Sleepers

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers compare sleep patterns in adults with clinical insomnia and matched healthy sleepers after a controlled bout of exercise designed to cause temporary soreness. Sleep is tracked with wrist activity monitors and daily sleep diaries, before and after soreness. The goal is to see if acute muscular pain changes sleep quality and duration differently in those with insomnia versus healthy controls.
