A study found a link between children's and parents' sleep problems, with mothers more susceptible to daytime sleepiness due to their greater responsibility for responding to child sleep issues at night. Parents need to recognize that their children's sleep disorders can take a toll on them, affecting quality of life.
A recent study published in the journal SLEEP found that treating insomnia is far less costly than ignoring it, with costs ranging from $924 to $1,143 for six months prior to treatment. The study suggests that addressing insomnia can lead to significant cost savings for individuals and employers.
A study of patients with type 1 diabetes and healthy individuals found that only one patient with T1DM woke up in response to hypoglycemia, compared to ten healthy control participants. The researchers also discovered that increases in plasma epinephrine concentration preceded polysomnographic signs of wakefulness.
A new communication protocol, SCP-MAC, has been developed to optimize energy efficiency for wireless sensor networks, reducing monitoring time from 2-3% to under 2 minutes per day. This improvement enables sensornets to watch wildlife or oilfields with longer-lasting batteries.

Parents and teens can improve school performance by following recommended sleep habits.
A Northwestern University study found that getting inadequate sleep increases the risk of being overweight in children. The five-year study, conducted on a nationally representative sample of 2,182 children aged 3-18, suggests that even an extra hour of sleep can reduce a child's chance of being overweight.
A new study reveals that African-American and poor children are more vulnerable to the effects of sleep disruption on their cognitive function, with poorer performance on school-related tests. The study suggests that health-related disparities between different groups of American children have important consequences.
A new study published in Child Development found that children who sleep more have lower BMI measures and are less likely to be overweight five years later. Sleeping an additional hour reduced young children's chance of being overweight from 36% to 30%, while it reduced older children's risk from 34% to 30%.
A new study published in the journal Sleep reveals that parasomnias are common and frequent in children. Pediatricians should actively involve parents in identifying symptoms and taking an active approach to helping their child overcome a sleep disorder. Home videos and sleep diaries can be useful tools for classifying parasomnias.
A study by Chiara Cirelli and colleagues shows that the quality and intensity of wakefulness affect slow-wave activity (SWA) during subsequent sleep. High exploratory activity during wakefulness leads to increased brain-derived neurotrophic factor (BDNF) expression, which in turn affects SWA.

He found that even highly fit athletes experience cardiac fatigue under such conditions, with the heart pumping less blood at the end of the race compared to the beginning.
Sleep disturbance in the elderly is associated with decreased memory, impaired concentration, and impaired ability to function. Geriatricians recommend addressing sleep problems through lifestyle changes, such as keeping a diary to track sleep patterns, and trying daytime walks and environmental adjustments to improve sleep quality.
Researchers have discovered that sleep improves memory consolidation by strengthening recently learned word pairs and making them more resistant to interference. The study found that sleep benefits declarative memory, a type of memory linked to the brain's hippocampus, particularly when faced with competing information.
A study found that diphenhydramine hydrochloride did not improve infant sleep or parents' happiness with their children's sleep. Parents who took the medication experienced no significant difference in nighttime awakenings or parental satisfaction with their child's sleep.
A new study by Georgetown University Medical Center found that diphenhydramine, a widely used antihistamine, has no benefit in helping infants and toddlers sleep. The study involved 44 children aged 6-15 months and showed only 1 out of 22 children improved sleeping after using the drug.
Researchers found that severe hot flashes are associated with chronic insomnia in postmenopausal women. More than 81% of women with regular severe hot flashes reported symptoms of chronic insomnia, including difficulty falling asleep and non-restful sleep.
Researchers found a significant association between hot flashes and insomnia in midlife women, with severe hot flashes increasing the risk of chronic insomnia. The study suggests that treating hot flashes may be an effective way to improve sleep quality in these patients.
A study found that ROZEREM was effective in promoting sleep and did not cause lingering effects the next day. The medication was associated with a decrease in time to fall asleep compared to placebo.
Researchers found that serotonin increases the amount and quality of sleep in fruit flies, even improving sleep in mutant flies with sleep deficits. The discovery highlights a potential link between serotonin's role in learning and memory and its effect on sleep.
A study of 321 Finnish parents found that both active and passive TV viewing were associated with shorter sleep duration and increased sleeping difficulties. High levels of passive exposure to TV, especially adult-targeted programs, were strongly linked to sleep disturbances.
A large study of 68,183 middle-aged women found that those who slept 5 hours or less per night were more likely to experience major weight gain and become obese over 16 years. The researchers didn't find a link between sleep duration and physical activity levels.
A Mayo Clinic study reveals that comas are often grossly misrepresented in movies, with inaccurate depictions of patients' appearances and care. The researchers propose solutions to improve accuracy in film portrayals, including collaborations between screenwriters and neurologists.
Researchers found that melatonin improved sleep efficiency during non-natural sleep periods, but not during natural sleep cycles. The study used 36 healthy young adults who took melatonin supplements to aid sleep at irregular times.
Patients with severe sleep-disordered breathing have a higher prevalence of arrhythmias, particularly atrial fibrillation and nonsustained ventricular tachycardia. The study found that individuals with SDB are more vulnerable to nocturnal cardiac arrhythmias and sudden death.
