Florida International University Study Links Anxiety to Altered Sleep Patterns in Preteens

Miami Fort Lauderdale, FL, September 9, 2026 —

Researchers at Florida International University (FIU) in Miami have identified a correlation between anxiety levels and sleep disturbances in preadolescent children. The study suggests that for highly anxious children aged 10 to 13, the size of their pineal gland may be linked to poorer sleep outcomes.

The pineal gland, a small endocrine gland located in the brain, plays a critical role in the body’s production of melatonin, a hormone essential for regulating sleep-wake cycles. The FIU study observed a paradoxical finding: in preteens experiencing high levels of anxiety, a larger pineal gland was associated with reduced sleep quality and an increased duration of time required to fall asleep. This contrasts with typical biological expectations where gland size might correlate with function or output in a more direct manner.

The specific details regarding the methodology, the exact number of participants, and the precise measurements of pineal gland size were not provided in the summary. Similarly, the timeline for the study’s commencement and completion, or whether further research phases are planned, were not detailed.

The findings highlight a potential area of concern for pediatric health, indicating that anxiety in this age group may manifest in complex physiological ways that impact fundamental functions like sleep. The research team at FIU is based in Miami, Florida. The implications of this link could inform future approaches to understanding and addressing sleep issues in children who experience anxiety.
