A study by King's College London found that babies introduced to solid foods early slept longer and woke less frequently at night compared to those exclusively breastfed for six months. This research challenges current government advice, which states that starting solid foods won't make babies more likely to sleep through the night.
A randomized clinical trial found that early introduction of some solid foods, accompanied by continued breastfeeding, resulted in small but significant improvements in infant sleep. The study also showed that the timing of introducing solid foods may influence infant sleep patterns.
A recent study published in the European Respiratory Journal found that obstructive sleep apnea is associated with changes to brain structure similar to those seen in early-stage dementia. The study suggests that screening for OSA and treating it could help prevent dementia in older adults.
Two studies presented at EULAR 2018 found that sleep problems predict the onset of chronic widespread pain and are associated with chronic pain in adolescents. Sleep difficulties, fatigue, and anxiety were identified as key predictors of chronic pain.
A study of 829 adolescents found that both short sleep duration and poor sleep efficiency are associated with increased abdominal fat deposition and cardiometabolic risk. In contrast, longer sleep duration and higher efficiency were linked to reduced waist circumference, lower blood pressure, and improved HDL cholesterol levels.

Researchers at Rockefeller University discovered that glial cells play a crucial role in regulating sleep and movement in worms, offering new insights into the neuroscience of sleep. The study found that glial cells help counteract the inhibitory effect of a specific neuron on movement.
Researchers found stroke patients took longer to fall asleep, had poorer sleep efficiency, and were more prone to errors during the day. The study suggests sleep problems in stroke patients are due to psychological strain, pain, and reduced physical activity, highlighting the importance of good sleep for recovery.
Researchers at Duke-NUS Medical School have identified CK1 as the priming kinase that 'switches on' the biological clock's phosphorylation process, shedding light on circadian rhythm regulation. This discovery may lead to treatments for circadian clock disorders and improve sleep-wake cycles.
Researchers found that sleep spindles, brief bursts of brain activity, are linked to memory reactivation and improve retention. The rhythmic pattern of spindles may help segregate memories, preventing interference between them.

Researchers found that just one simulated night shift altered levels and time-of-day patterns of over 100 proteins in the blood. These disruptions can lead to higher diabetes rates and decreased energy expenditure, highlighting the importance of timing treatments around the circadian clock.
A new study from the University of Illinois found that mothers who don't get enough sleep or have poor quality sleep are more likely to engage in permissive parenting with their adolescents. Mothers who receive adequate sleep, on the other hand, are less likely to be permissive and report better parenting behaviors.
Researchers analyzed human plasma proteins over time, identifying 30 proteins regulated by the circadian clock and affecting cancer, immune function, and metabolism. Circadian misalignment altered glucose homeostasis and energy metabolism pathways.
Chronic short sleep duration, independent of extended wakefulness, results in vigilant performance impairments, with attention lapses increasing fivefold and reaction time doubling. Participants on restricted sleep schedules worsened over time, suggesting they cannot adapt to chronically insufficient sleep.
A randomized placebo-controlled study found that CPAP treatment significantly lowered resting heart rates during the day and night in patients with OSA and prediabetes. The effects were comparable to those of beta blockers, which block stress hormones and raise heart rates.

Scientists found that brief sleep arousals are triggered by wake-promoting neurons' electrical noise, which is affected by body temperature. Higher temperatures may lead to fewer and shorter arousals, potentially increasing the risk of Sudden Infant Death Syndrome (SIDS).
Experiencing rude behavior at work is linked to insomnia symptoms, but taking mental breaks can improve sleep quality. Employers can encourage programs aimed at reducing workplace incivility.
Researchers detected periodic movement in tree branches and leaves, revealing a previously unknown water transport mechanism. This discovery suggests that trees are pumping water and may have shorter or longer sleep periods than previously thought.
The American Academy of Sleep Medicine advises against using medical marijuana to treat sleep apnea due to unreliable delivery methods and insufficient evidence on its effectiveness and safety. Effective treatments like CPAP therapy are available from licensed medical providers.
A new study found that individuals with tetraplegia and sleep apnea have distinct responses to airway narrowing, leading to increased risk of sleep disruption. This knowledge can inform targeted therapies for those affected by the condition.

A study of over 10,000 infant deaths found that many were caused by unsafe sleep positions or environments. Licensed childcare providers were more likely to follow safe sleep guidelines than babysitters, relatives, and friends. The researchers urge parents to educate anyone caring for their children on safe sleep practices.
