This suggests that genetic influences on body weight may be suppressed by adequate sleep duration.
A study finds that sleepiness in college students leads to counterfactual thinking, including thoughts of how others could have done better. Sleepy individuals are also more likely to engage in displaced aggression and plan revenge.
A study of 508 children found a strong association between childhood excessive daytime sleepiness (EDS) and obesity, asthma, anxiety, and depression. Waist circumference was also significantly associated with EDS, suggesting metabolic factors play a role.

A study found that CPAP treatment significantly reduces daytime sleepiness and increases wakefulness in patients with very mild symptoms of obstructive sleep apnea. The treatment also improves quality of life scores, even among those who initially did not perceive a benefit from therapy.
Researchers found that marital instability at 9 months old predicts child sleep problems at 18 months, including difficulty falling asleep and staying asleep. This relationship persists even after controlling for factors such as birth order, parents' anxiety, and infant temperament.
A recent study of over 350 families found that marital instability when children are 9 months old can lead to sleep problems by 18 months. The research suggests that parents should be aware of the potential impact of marital stress on their child's well-being during the first year or two of life.
Approximately 14% of all strokes occur during sleep, preventing patients from receiving timely clot-busting treatment. Researchers estimate that around 58,000 people in the US go to the emergency department with a wake-up stroke each year.

The discovery suggests that the transition to a dark environment may be associated with changes in sleep behavior, potentially due to the need for continuous vigilance to find food.
A longitudinal study suggests that older adults with moderate to severe sleep apnea who experience excessive daytime sleepiness are more than twice as likely to die. The study found no significant increase in mortality risk among those with only excessive daytime sleepiness or sleep apnea alone.
A new internet-based intervention reduced infant and toddler sleep disturbances by 50%, while also improving maternal sleep and mood. The customized sleep profile provided individualized recommendations, leading to significant improvements in sleep quality and duration.
