A new study has found a link between sleep and mental health, showing that sleep disturbances are prevalent across psychiatric disorders. Dr. Sarah Chellappa says understanding the interaction between sleep and mental health is crucial for developing effective interventions. Those susceptible to mental health disorders often encounter disruptions in sleep and circadian rhythms during their formative years. Insomnia is prevalent in individuals with mood disorders, with up to a third experiencing both insomnia and hypersomnia. Circadian rhythm sleep-wake disorders, such as insomnia, play a role in conditions like BPD, impacting sleep timing and cortisol patterns. The researchers advocate for targeted interventions, as environmental factors have been shown to influence mental health outcomes. This includes making adjustments to school and work schedules or optimizing light exposure throughout the day.
