This observational study is looking at how different body rhythms, like your sleep, heart rate, and menstrual cycle, are connected in young women. Researchers will monitor your movement, sleep, heart rate, oxygen levels, gut health, and light exposure over 28 days. They want to understand how these different cycles interact with each other and with your body's natural 24-hour clock (circadian cycle). The main goal is to measure your stride time (how long it takes to take a step) after 28 days. You can join if you are a woman between 18 and 30 years old with a regular menstrual cycle. The study is currently unclear on its recruitment status and does not involve any specific interventions or drugs.

Study design

This is an observational study with 20 planned participants. It is not testing a specific drug or treatment.

What's involved

You will wear devices for 28 days to track various body measurements. You will also provide saliva samples twice for 7 hours and two blood samples during those times, plus daily urine samples.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, stride time, is measured at 28 days. It is not specified if there is follow-up after this point.
