Human Research Coordination

This study is investigating the reproducibility of a 24 hour ambulatory monitor in healthy young adults. It’s a relatively simple study with all the tests done at home. Briefly, you will be asked to wear the blood pressure monitor a total of 2 times. First we will do the consenting procedures and study familiarization (~1 hour). Following consenting, you will be asked to wear an at-home ambulatory blood pressure monitor for two separate 24-hour periods, each period being separated by 4 weeks. During each time you wear the blood pressure monitor, you will also be asked to wear a sleep watch and do overnight urine collection.

You may not be able to participate if:

• Are unwilling or unable to give consent
• Have been diagnosed with any chronic disease (a history of high blood pressure, heart disease, diabetes, cancer, kidney disease)
• Currently take medication that may alter blood pressure
• Have been diagnosed with a sleep disorder (e.g., insomnia, restless leg syndrome, sleep apnea)
• Currently take any supplements or medications for sleep or known to alter sleep (e.g., Ambien, sedatives, melatonin, etc.)
• Currently work night-shift work
• Resting blood pressure >130/80 mmHg
• Body mass index 30 kg/m2
• Currently pregnant or breast feeding (women only)
• Currently use tobacco (≥1 cigarette in the last month)
• Have had a positive COVID-19 test within the past 60 days or have received a COVID-19 vaccination within the past 14 days

You are being asked to participate because:

• You are between 18-30-years-old (women must be premenopausal)
• You have a BMI between 18.5-29.9 kg/m2
• You have a seating resting systolic and diastolic blood pressure < 130 and < 80 mmHg
