Studysummary This study found that individuals with both schizophrenia and obesity showed reduced PER3 gene expression amplitude and lower melatonin levels compared to normal-weight controls, suggesting dampened circadian rhythms linked to irregular sleep. Hair follicle sampling was effective for assessing these molecular rhythms.
