A recent study links adolescent sleepiness to future crime rates, with sleepy teens more likely to commit crimes by age 29. The study suggests that poor daytime attention and social adversity may contribute to the relationship between sleepiness and crime.
Research from the University of Pennsylvania and University of York found that teenagers who self-report feeling drowsy mid-afternoon are 4.5 times more likely to commit violent crimes a decade and a half later. The study also links daytime sleepiness with poor attention and brain function, which can lead to criminal behavior.

A study published in eLife reveals that a single nerve cell named ALA coordinates an organism-wide response to sickness, causing sleepiness by releasing FLP-13 and other neuropeptides. Researchers found that FLP-13 triggers sleep by turning down activity in nervous system cells that help keep organisms awake.

Researchers found that brain cells in specific columns cycle independently between active and inactive states during both sleep and wake. This cycling is linked to improved attention and response to external stimuli.
A study published by The Menopause Society confirms electro-acupuncture's effectiveness in reducing hot flash severity and improving sleep quality in breast cancer survivors. Electro-acupuncture has been shown to affect neurotransmitters associated with sleep, such as serotonin and melatonin.
Researchers at Concordia University have designed a new software solution called Hypnoguard to safeguard laptop data while the computer is in sleep mode. The system uses encryption and password-based authentication to protect critical data from unauthorized access.
A new study found that parental confidence in helping children get enough sleep is positively associated with child sleep duration. Additionally, higher parent sleep duration was also linked to increased child sleep duration, suggesting that addressing insufficient sleep among children may require family-based interventions.
Researchers discovered that flies slept more after consuming larger meals, with protein and salt promoting sleep. The study suggests that 'food coma' might be a natural adaptation to maximize gut absorption of essential nutrients.
Scientists have found that protein and salt in food can drive post-meal sleepiness in fruit flies, leading to longer naps. The study used a system to measure feeding and sleeping behaviors of individual flies, revealing that larger meals result in longer sleep periods.
Research by QUT's Centre for Accident Research & Road Safety - Queensland found that driver distraction and sleepiness account for approximately 25% and 20% of road crashes respectively. Younger drivers are more vulnerable to these risks due to their developing sleep-wake systems.
Research found that short and poor quality sleep were associated with a lower risk of developing kidney failure, while higher sleep fragmentation increased the risk. Patients who experienced daytime sleepiness also had a higher risk of death during follow-up.
Biochemists from Trinity College Dublin have discovered indolepyruvate, a metabolic by-product of trypanosome activity, which may offer possibilities for developing anti-trypanosome drugs. Inhibiting its production could be key in fighting the parasite, which causes sleeping sickness and kills millions in sub-Saharan Africa.
A recent study published in PLOS ONE found a significant association between increased smartphone screen-time and lower sleep quality. Over 650 adult participants recorded their daily screen-time using a smartphone application, revealing that longer screen-time periods were linked to poorer sleep quality and less sleep overall.
Researchers found people with early Alzheimer's disease have different daily patterns of activity than those without the disease, spending less time in moderate-intensity activities. Customized interventions targeting morning physical activity may help improve sleep and slow cognitive decline.
A new UCL study found that mismatched light and heat levels can cause major disruptions to body clock function, leading to behavioral changes and molecular signals. The research suggests that a moderate time lag between light and temperature causes the clock to break down, with significant effects on behavior.
Researchers at Brown University have developed a new interactive sleep app, SleepCoacher, that uses sleep analytics to provide personalized recommendations. The app guides users through self-experiments to find the most effective recommendations for improving their sleep.
