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.
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 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 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.

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.
A study suggests that honey is more effective than over-the-counter cough medicines in relieving children's coughs and improving sleep during colds. Honey was found to yield the greatest improvement compared to no treatment or dextromethorphan, an over-the-counter medication commonly used for children's coughs.
A study found that buckwheat honey provided better relief of nighttime cough and sleep difficulty in children than no treatment or dextromethorphan, a common cough suppressant. The study showed honey reduced the severity, frequency, and bothersome nature of nighttime cough from upper respiratory infections.

The Lancet seminar highlights the need for a collaborative approach to prevent SIDS, emphasizing the importance of campaigns like placing infants on their backs during sleep. Other risk factors include maternal smoking, soft bedding, and bed sharing, while room-sharing without bed-sharing has been shown to reduce SIDS risk.
A five-year longitudinal observational cohort study found that anxiety is strongly associated with sleep disturbances. Those who experience severe life events are more likely to develop sleep disturbances, especially if they already have a predisposition to anxiety.
Researchers found that African-American college students reported poorer sleep quality, slept less time, and took longer to fall asleep compared to whites. These findings suggest that ethnic differences in sleep quality may be linked to higher blood pressure risk and 'blood pressure dipping',

A study published in JCSM found that 58% of OSAHS patients reported ever using complementary and alternative medicine (CAM) therapies, with a high interest in future use. This highlights the importance of considering CAM options for these patients and underscores the need for further research on their effectiveness.
A new self-completed instrument, the Cleveland Adolescent Sleepiness Questionnaire (CASQ), measures excessive daytime sleepiness in adolescents. CASQ scores are positively correlated with age and display convergent validity with other surveys, showing promise as a valid measure for clinicians and parents.

The American Academy of Sleep Medicine offers tips to help children sleep better, including establishing a consistent bedtime routine and creating a relaxing environment.
A large-scale study of 2,889 older women found that poorer sleep is associated with worse physical function during the day. Women who slept less than six hours per night walked slower and took longer to complete daily activities. Maintaining good sleep hygiene is crucial for optimal daytime function in older adults.

The study also discovered that living in an inner city was associated with increased risk of short sleeping, while non-urban areas were linked to reduced risk of long sleeping.
A study published in SLEEP found that adolescents who used their cell phones after bedtime were more likely to experience tiredness the next day. The researchers, led by Jan Van den Bulck, discovered that frequent phone use increased the risk of tiredness, with those using their phones daily being up to 5 times more likely to feel tired.
Pregnant women exposed to passive smoking experience sleep disturbances, including subjective insufficient sleep, difficulty initiating sleep, short sleep duration, and snoring. The study also found that pregnant women who smoke experienced similar sleep issues, as well as excessive daytime sleepiness and early morning awakening.
A study published in the SLEEP journal found that work time has the largest reciprocal relationship to sleep time, with respondents working longer hours sleeping less. The study analyzed data from over 47,000 participants and found that travel time was also an unexpected factor affecting sleep.
Researchers at Cornell University have created a mathematical model to describe the internal clock in living beings, which regulates sleeping and waking patterns. The study proposes that an extra protein may be necessary for the circadian cycle to extend over 24 hours.
A new study reveals that restless legs syndrome is common and troublesome in children and adolescents, occurring more frequently than diabetes and epilepsy. The condition, characterized by sensations in the legs, affects nearly 2% of US/UK children aged 8 to 17, with a significant proportion experiencing moderate to severe symptoms.
A study by Louise Hawkley and John Cacioppo found that loneliness accumulates over time and contributes to increased stress, chronic inflammation, and poorer sleep quality in older adults. The researchers also discovered that lonely individuals exhibit a heightened state of arousal and are less likely to seek help when stressed.
A recent study published in PLOS Medicine found that a free mass distribution program increased ITN use among Kenyan children from 7% to 66%. The high rate of adoption was consistent across different family income levels. The researchers argue that making ITNs freely available is crucial for achieving high levels of use and saving lives.
Researchers at Rutgers University are studying the connection between thyroid hormones and sleep. The study aims to identify how thyroid hormones affect brain structures during sleep and wakefulness.
