Infants and toddlers who sleep less than 12 hours a day are twice as likely to become overweight by age 3. High levels of television viewing combined with less sleep elevates the risk, especially when children watch TV for two or more hours a day.
A study found that certain parenting behaviors, such as cosleeping and giving food to children after waking, can lead to sleep disturbances later in childhood. These behaviors were associated with bad dreams, short total sleep time, and delays in falling asleep.
A Université de Montréal study found that parents' bedtime behavior has a direct impact on children's sleep patterns. Giving children food or drink after they wake can cause bad dreams, short sleep time, and delays in falling back asleep. Staying with children at the beginning of sleep appears protective against these issues.
A genetic screen revealed that Drosophila mutants with lower arousal thresholds have difficulty staying asleep, likely due to hyperarousability. This finding suggests that changes in arousal threshold may be a common mechanism underlying sleep regulation and is relevant to human insomnia.
A study found that persistent insomnia increased the risk of remaining depressed and achieving less than 50% clinical improvement. Elderly patients with major depressive disorder were more likely to remain depressed if they had persistent insomnia, regardless of treatment type.
A study found that both short and long sleeping times are associated with an increased risk of future body weight and fat gain in adults. Adults who slept less than 7 hours or more than 10 hours per night gained more weight over six years compared to those who slept for 7-8 hours.
A new study published in Sleep confirms that insomnia increases the risk of subsequent depression among young adults. The study, which followed 591 participants over 20 years, found that insomnia was a chronic problem that preceded depression more consistently than vice versa.
Dr. Tracy Rupp won the National Sleep Foundation Young Investigator Award for her work on sleep extension and its effects on performance and task acquisition. She demonstrated that extended sleep has a 'banked' recuperative value, contrary to current thinking.
Researchers found that poor sleep is strongly associated with high levels of psychological distress, depression, anger, and hostility in women. Women who reported longer time to fall asleep had higher levels of inflammatory proteins and insulin.
A recent study published in the Journal of Labor Economics found that television schedules have a larger impact on people's daily routines than natural daylight patterns. The research reveals that Americans' sleep and work patterns are shaped by artificial time zones and TV broadcast schedules, rather than the sun's cues.
Loud snoring with breathing pauses is associated with an increased risk of hypertension, heart attacks, and strokes. Quiet snoring is linked only to an increased risk for hypertension in women. The study found that loud snoring carries a significantly increased risk for cardiovascular disease.
A study published in SLEEP found that children with obstructive sleep apnea (OSA) exhibit abnormal respiratory-related evoked potentials, indicating reduced protective responses to upper airway collapse. This may explain why children with OSA develop the condition despite normal arousals to non-respiratory stimuli.
A study published in the journal SLEEP found that both insomnia patients and normal sleepers define sleep quality by tiredness upon waking and throughout the day. Individuals with insomnia have more requirements for judging sleep to be of good quality, including a greater need for restful nights and fewer allowed awakenings.
A new study published in the journal Sleep reveals that narcolepsy patients have a high prevalence of eating disorders, with half reporting persistent cravings and binge eating. The study also found no correlation between weight gain and binge eating, suggesting metabolic alterations may be involved.
Researchers found that daytime dozing significantly increases the risk of stroke in older adults. Moderate dozing doubled the risk, while significant dozing quadrupled it. The study suggests that sleep problems may be an important and novel stroke risk factor.
A study of nearly 300 preschool children found that those who don't get adequate sleep are twice as likely to suffer injuries. The study suggests that ensuring sufficient sleep can help reduce the risk of childhood injuries.

Research reveals that doctors are reluctant to prescribe sleep aids to patients with depression, anxiety, or mood disorders, except for psychiatrists. However, new guidelines are needed to address this knowledge gap and ensure patients receive appropriate treatment for their insomnia.
A study published in the journal SLEEP found that respiratory disturbances during sleep are remarkably common in healthy individuals, particularly in older adults. The prevalence of breathing irregularities increases dramatically with age, even in those without symptoms or signs of obstructive sleep apnea syndrome.
Researchers found that dreams after 9/11 showed more intense imagery but not longer or more bizarre content, contradicting expectations. The study suggests a link between the traumatic event and increased emotional intensity in dreams.
A study published in the journal SLEEP found that a brief daytime nap (45 minutes) benefits declarative memory performance. The results suggest that there is a threshold acquisition level required for sleep to optimally process memories, and this finding has implications for adults' nightly sleep recommendations.
A study of over 4,000 US adolescents found chronic insomnia can predict somatic and psychological problems in the future. Insomnia is a major public health burden among adolescents, comparable to other psychiatric disorders.
Researchers found that increasing core body temperature improved vigilance, while decreasing skin temperature enhanced wakefulness in narcoleptic subjects. The study used a thermosuit to manipulate skin temperature and hot or cold food/drinks to adjust core body temperature.
A study published in SLEEP found that higher periodic leg movement index (PLMI) predicted less sleep at night in older people with cognitive impairment. The study, conducted by Kathy C. Richards of the University of Pennsylvania, assessed 102 participants and found that PLMI explained 43.6% of the variance in total sleep time.
New research from the University of Wisconsin-Madison found that synapses, nerve cell connections central to brain plasticity, are strong when awake and weak when asleep. This challenges the widely-held idea that sleep is essential for consolidating information through synaptic strengthening.
A 90-minute daytime nap significantly speeds up memory consolidation, with participants showing improved performance in tasks requiring motor skills. This discovery may enable the development of methods to accelerate memory consolidation and create stable memories.
A new study published in the journal SLEEP found that continuous positive airway pressure (CPAP) can effectively treat catathrenia, a rare sleep disorder characterized by involuntary groaning during sleep. The study treated seven female patients with CPAP, resulting in the elimination of the groaning sound in all cases.
A study published in SLEEP finds that zolpidem extended-release improved sleep onset and maintenance, as well as concentration and morning sleepiness in people with chronic primary insomnia. The medication showed sustained benefits over six months, with no evidence of rebound insomnia upon drug discontinuation.
A study found that people with untreated obstructive sleep apnea (OSA) have weakened heart rate recovery after maximal exercise, suggesting an imbalance in autonomic control. This may be an early clinical sign of OSA progression.
A study found that children who don't get enough nightly sleep are more likely to be overweight and have behavioral problems. Sleep duration was shorter on weekends, in the summer, and when bedtime was after 9:00 p.m.
A study using the Transtheoretical Model found that over 60% of OSA patients were at pre-action stages, with less than 30% reporting maintenance. The model suggests that increasing exercise and reducing body mass may be a practical route for managing mild sleep apnea.
The American Academy of Sleep Medicine (AASM) has approved home sleep testing as a tool to detect moderate to severe obstructive sleep apnea (OSA) in select adults. Home sleep tests are recommended for adults between 18 and 65 with high pretest probability of OSA and no comorbid medical conditions.
A study published in the Journal of Clinical Sleep Medicine found an association between short sleep times and obesity in patients with chronic medical problems. The results suggest that adults should aim for eight to nine hours of sleep per night to maintain optimal weight.
Researchers identified two blind individuals with intact non-visual responses to light, highlighting the functional distinctness between visual and non-visual pathways. The study found that short-wavelength blue light induced significant effects on circadian rhythms, melatonin secretion, and alertness in both patients.
A new study published in JAMA found that the sedative drug dexmedetomidine improves intensive care sleep quality and reduces instances of coma and delirium compared to lorazepam. The study showed that dexmedetomidine resulted in 30% fewer patients experiencing coma and an average of four more coma-free days.
