Sleep

Recent research found 60% of adults with ADHD experience sleep disorders, often linked to psychiatric comorbidities. Systematic screening could improve understanding and treatment of both sleep and mental health issues in this population.

Recent research found that short, frequent cold-water immersions improved cognitive performance on specific tasks, reduced sleep disturbances, and lowered worry levels, without affecting overall well-being or selective attention.

Reactivating positive memories during sleep weakens recall of negative memories, increases spontaneous positive memory intrusions, and enhances positive emotional judgments, suggesting a potential sleep-based approach for managing distressing memories and improving emotional well-being.

People with dissociative symptoms often have fragmented, incoherent dreams, higher nightmare distress, and more lucid dreaming, suggesting that dream patterns and REM sleep disturbances are linked to a fragmented sense of self.

New research sheds light on why some individuals are more prone to frequent nightmares, pointing to thin psychological boundaries and a trait called nightmare proneness as significant factors.

Children with consistent sleep schedules show better emotional regulation, reduced impulsivity, and stronger social skills. Irregular sleep timing was linked to poorer behavior, but early parenting interventions mitigated these negative effects.

Individuals who consumed psilocybin in a therapeutic context reported modest, sustained improvements in sleep, with baseline sleep disturbances influencing the likelihood of achieving depression remission.

Daytime sleepiness is linked to higher body weight. Men with chronic sleepiness have consistently higher BMI, while women, especially younger ones, gain weight faster when sleepiness increases over time.

Humans evolved to co-sleep, benefiting bonding and safety but with mixed effects on sleep quality. Cultural norms and individual needs influence bedsharing, which varies across life stages, with unclear long-term developmental or health impacts for children and adults.

Northwestern researchers found that a smartphone app using sensory cues significantly increased lucid dream frequency. Participants experienced nearly triple their usual rate of lucid dreams, showing that the Targeted Lucidity Reactivation method is effective outside the lab.

People with insomnia experience heightened morning hyperarousal, especially after poor sleep. This link suggests that improving sleep quality may help reduce daytime hyperarousal symptoms in insomnia.

Daily energy drink consumption among students is linked to shorter sleep duration, poorer sleep quality, and increased insomnia symptoms compared to those who rarely or never consume energy drinks.

A study found that higher stress levels in university students led to increased bedtime procrastination, resulting in shorter sleep duration and lower sleep quality. Bedtime procrastination mediated the link between daily stress and poor sleep outcomes.

Objective sleep data has confirmed that evening types take longer to fall asleep, especially those with a history of depression.
