Lack of Sleep in Teens Linked to Higher Suicide Risk

Teenagers who sleep less or experience frequent night awakenings are significantly more likely to attempt suicide later in adolescence, according to a major longitudinal study. Researchers analyzed data from more than 8,500 teens and found that poor sleep at age 14 predicted suicide attempts by age 17, even after accounting for other mental health risk factors.

This shows two people sleeping. One has a clock in the background, the other has a brain and other organs in the background, implying poor sleep may harm health.

Irregular Sleep Linked to 172 Diseases

In the largest study of its kind, researchers linked irregular sleep patterns to elevated risk for 172 diseases. Using objective sleep data from actigraphy devices worn by over 88,000 people for nearly seven years, the study found that erratic bedtimes and poor circadian stability were among the most damaging traits.

Hitting Snooze Disrupts REM Sleep

Despite expert warnings, hitting the snooze button is a common part of many people’s morning routines. A large global study analyzing data from over 21,000 individuals found that snoozing occurred in 56% of sleep sessions, with heavy users snoozing for up to 20 minutes each morning.

Why OCD, Tics, and ADHD Keep You Up at Night

People with obsessive-compulsive spectrum disorders (OCSDs), chronic tic disorders (CTDs), and ADHD often suffer from significant sleep disturbances, and a new review suggests that disruptions in the cortico-striatal-thalamo-cortical (CSTC) pathway may be the reason why. The review highlights how dopamine and GABA dysregulation in CSTC circuitry contributes to both poor sleep and the disorders themselves, suggesting a bidirectional and additive relationship.

Poor Sleep Linked to Brain’s Waste-Removal Breakdown

A new study reveals that poor sleep in older adults disrupts the brain’s glymphatic system, responsible for clearing harmful waste and toxins. Researchers found that compromised sleep quality leads to dysfunction in this crucial system, potentially increasing risks for memory decline and cognitive impairments.

Dogs with Dementia Suffer Similar Sleep Problems to Humans

A new study found that dogs with dementia suffer similar sleep disruptions as humans with dementia. Using EEGs, the researchers found that dogs with advanced dementia had more sleep disruptions and slept less overall than dogs with normal cognitive function. The findings could help with early diagnosis and intervention for dogs with cognitive decline and could establish them as models for Alzheimer's disease.
