A study from the University of Vaasa examines the effects of insufficient sleep on work performance and presents practical methods for identifying and managing its impacts. Employees who suffer from fatigue should enhance their coping skills by scheduling tasks based on difficulty and slowing down their work pace.
Researchers identified a brain signal involved in impaired attentional control from sleep deprivation that could predict worsened athletic performance. Athletes with stronger attention control may be more easily able to overcome the negative effects of lack of sleep and stress on their competitive performances.
Despite severe sleep deficits, insomniac fruit fly mutants exhibit enhanced memory performance through altered PKA signaling in the mushroom body. This finding suggests a complex relationship between sleep and memory functions.

Research reveals that even a single night of sleep deprivation can alter the profile of immune cells, similar to those found in individuals with obesity. This suggests that the immune system is highly sensitive to sleep patterns and may contribute to long-term inflammatory states and increased risk of disease.
A Michigan State University study reveals racial and ethnic disparities in children's sleep patterns, with non-white and multiracial children experiencing more significant variability in bedtime and rise time. The research emphasizes the importance of addressing systemic inequities to promote healthy sleep equity among all children.
A new study reveals that sleep deprivation can inhibit the brain's ability to suppress unwanted memories and intrusive thoughts. Researchers found that well-rested individuals showed more activation in a specific brain region when attempting to suppress memories, while sleep-deprived individuals struggled with this task.
A new study published in PNAS found that sleep deprivation leads to memory control deficits, making it harder to suppress unwanted memories. REM sleep rejuvenates brain regions that support memory inhibition, reducing the likelihood of intrusive memories.
