{"abstract":"This article explores the relationship between sleep and mood, highlighting sleep's essential role in physical and mental health. It explains that insufficient sleep negatively impacts mood, leading to increased irritability, stress, and anxiety, and impairs concentration. The article details three key mechanisms through which sleep influences mood: regulating emotions by producing and processing mood-related hormones and neurotransmitters like serotonin; consolidating memories and processing emotions, which aids in making sense of experiences, coping with negative emotions, and developing positive emotional regulation; and reducing inflammation, a factor implicated in mental health disorders such as depression and anxiety. The text concludes by noting a strong link between sleep deprivation and mood disorders, observing that individuals with depression and anxiety often experience sleep problems, and those with insufficient sleep are more prone to developing these conditions.","abstract_source":"gemini_generated","authors":["Jona Claudio"],"date":"2023-11-13","doi":"10.5281/zenodo.10116859","id":2240,"issue":1,"journal":{"issn":"xxxx-xxxx","name":"Akademika: Educational Learning Anthology"},"pdf_sha256":"a58cc80436baa9d5f040232a5e9512bfbb28dd8c9bb643a0a9c31b77b547c6e0","schema":"scimatic-article/1","title":"The Relationship between Sleep and Mood","volume":1}
