Additional Study Information: The Mailman School of Public Health at Columbia University is doing a research study to learn how improving sleep habits affects heart health. We are looking for adults aged 30+ years with no history of cancer or heart disease. To see if individuals qualify for the study, those who are interested in participating will first do an in-person visit and their blood pressure will be taken. Qualifying participants will wear a wrist monitor to track their sleep habits for a week. $25 will be given for completing these screening activities. Individuals who qualify for the study will be invited to participate in the study. Participating in this research study involves 6- 8 study visits over 6 months, a blood draw, wearing a Fitbit wristband for the entire study time, wearing a blood pressure monitor three times for 24 hours each time, attending online and in-person sleep health education sessions, completing questionnaires, and receiving feedback from the study team. Participants will receive up to $525 for research activities (including screening).
