Understanding circadian rhythms and mental health
Our bodies operate on an internal clock known as circadian rhythms, which follow a 24-hour cycle. These rhythms are essential for nearly every process in our body and brain, influencing everything from sleep patterns to mood regulation. Circadian rhythms are shaped by both genetic factors and environmental cues, such as light-dark cycles and mealtimes. When these rhythms are disrupted, it can increase the risk of mental health issues like depression and addiction. Additionally, chronic stress and substance use can further disturb these rhythms, worsening mental health challenges.
While we know these connections exist, much of the current research is based on observed patterns rather than a deep understanding of how these systems interact. Our work aims to bridge this gap by investigating the detailed mechanisms that link circadian rhythms to behavior and mental health. We’re particularly focused on how these rhythms influence behaviors related to stress, reward, and motivation—key factors in disorders like depression and addiction. Using cutting-edge science, including genetics, molecular analysis, and advanced brain imaging, we study these processes at a molecular and cellular level. By uncovering these mechanisms, we hope to discover new approaches for treating mental health disorders.
