Welcome to the Sleep and Health in Everyday Life (SHEL) Laboratory in the Department of Psychology at UNT. The SHEL-Lab was founded in 2019 by principal investigator Dr. Danica Slavish.
In the SHEL Lab, we investigate several research questions related to sleep and health, including:
- How do daily stressful and emotional experiences impact sleep?
- Is irregularity in sleep a unique correlate of disease?
- Is inflammation a mechanism linking sleep, stress, and disease?
- How do these associations vary across different populations (e.g., shift workers, racial/ethnic groups, military personnel, college students)?
To examine these questions, we assess people in their everyday environments, using non-intrusive surveys and physiological assessments (e.g., actigraphy, salivary markers of inflammation). The goal of our research is to understand the structural and behavioral risk factors that increase susceptibility to sleep disturbances, in hopes of identifying targets to improve individuals' health and well-being. We also strive to promote transparency of our research methods by using the open-source statistical software R and by making our data publicly available on Open Science Framework.
