Purpose of Review <p>The goal of this paper is to describe the process of advocacy for sleep clinicians and researchers. We draw upon our own experiences as sleep advocates and include resources from the literature.</p> Recent Findings <p>While virtually every area of health and well-being is affected by sleep and circadian biology, including cardiovascular and cerebrovascular disease, obesity and metabolism, and mental health, sleep clinicians and researchers are often reluctant to advocate for our field, including communicating the importance of sleep, to lawmakers and other public stakeholders. We discuss the barriers along with rewards of sleep advocacy and present a primer on how to get started as a sleep advocate.</p> Summary <p>Sleep clinicians and researchers can play a critical role in advocating the importance of sleep and circadian biology for human health and well-being. We need to support our clinicians and resources in this endeavor.</p>
