Insufficient Sleep Strongly Predicts Shorter Life Expectancy

A new nationwide analysis shows that getting fewer than seven hours of sleep a night is one of the strongest predictors of shorter life expectancy across U.S. counties. Sleep sufficiency outperformed other behavioral factors—including diet, exercise, and loneliness—with only smoking showing a stronger association.

Insomnia Keeps the Brain Stuck in Daytime Mode

People with chronic insomnia show a delayed and weakened daily rhythm of mental activity, keeping the brain in a more alert, daytime-like state at night. Under tightly controlled conditions, individuals with insomnia failed to show the normal nighttime drop in goal-directed thinking seen in healthy sleepers.

Sleep-Wake Perception Intact in Many With Insomnia

A new study finds that patients with insomnia often retain accurate sleep-wake perception and intact regulatory systems, despite feeling as though they sleep poorly. Using serial awakenings during sleep lab monitoring, researchers found no significant difference in sleep perception between healthy individuals and those with insomnia.

Insomnia Isn’t Just About Sleep, Your Personality Plays a Role

Certain personality traits significantly influence the risk of developing insomnia. People with high levels of neuroticism—a trait linked to emotional instability—were much more likely to experience sleep disturbances.

Shared Brain Circuit Links Insomnia, Anxiety, and Depression

A large brain imaging study suggests that insomnia, depression, and anxiety—often co-occurring—share overlapping brain abnormalities. Researchers found reduced cortical surface area, smaller thalamic volume, and weaker brain connectivity across all three disorders, while each also displayed unique neural patterns.

What Poor Sleep Really Does to Your Brain

Chronic sleep disorders and short-term sleep deprivation affect different regions of the brain, highlighting distinct neural impacts. A meta-analysis of 231 brain studies showed that chronic sleep disorders alter regions involved in emotions and memory, while short-term deprivation primarily affects attention and movement regulation.

Screen Time in Bed Linked to Less Sleep, Higher Insomnia Risk

A new study of over 45,000 young adults found that using screens in bed increases the risk of insomnia by 59% and cuts sleep by 24 minutes. Surprisingly, the type of activity—whether social media, movies, or studying—didn’t make a difference; it was the screen time itself that mattered most.

Sleep-Deprived Fruit Flies Show Sharper Memory via PKA Signaling

Fruit flies with genetic mutations that severely reduce sleep show enhanced performance in olfactory memory tasks, challenging assumptions about sleep’s role in cognition. This paradox appears to be driven by increased protein kinase A (PKA) signaling in the mushroom body, a brain region responsible for memory and sleep regulation.

Poor Sleep Linked to Difficulty Controlling Unwanted Thoughts

Sleep deprivation impairs brain regions responsible for suppressing unwanted thoughts, contributing to mental health challenges. Functional neuroimaging revealed reduced activation in the prefrontal cortex and increased hippocampal activity in sleep-deprived individuals, suggesting memory control deficits.

Lack of Sleep in Childhood Linked to Increased Psychosis Risk

Children who consistently experience insufficient sleep from infancy through early childhood are significantly more likely to develop psychosis as young adults. Analyzing data from the Avon Longitudinal Study of Parents and Children, researchers found that chronic sleep deprivation is a strong predictor of both psychotic disorders and psychotic episodes later in life.
