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 a number of research questions related to sleep and health, including:
- Why do some people experience impaired sleep, both in general and from day-to-day?
- How do associations between stress, emotion, and sleep unfold across time?
- Is inflammation a mechanism linking sleep, stress, and disease?
- How do these associations vary across different populations (e.g., shift workers, racial/ethnic minorities, military personnel, college students)?
To examine these questions, we assess people in their everyday environments, using a combination of non-instrusive surveys and physiological assessments (e.g., actigraphy, salivary biomarkers of inflammation). The goal of our research is to understand the behavioral risk factors that increase susceptibility to sleep disturbance and disease, in hopes of identifying modifiable targets to improve individuals' sleep 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.
