Purpose in life by day linked to better sleep at night

Having a purpose in life means you are more likely to sleep better at night with less sleep apnea and restless leg syndrome, reports a new study. Cultivating a purpose in life could be drug-free strategy to improve sleep, scientists said. The study participants were older adults — who tend to have more insomnia and sleep disturbances — but researchers said the findings are likely applicable to the broader public. Source

Sufferers of both Type 2 diabetes and sleep apnea could lose eyesight within four years

Patients who suffer from both Type 2 diabetes and obstructive sleep apnea are at greater risk of developing a condition that leads to blindness within an average period of less than four years, new research has found. Source

Babies born to mothers with sleep apnea have higher risk of adverse neonatal outcomes

A new study is the first to demonstrate a higher risk of congenital anomalies and resuscitation at birth in newborns of mothers who have obstructive sleep apnea. Source

Air pollution may disrupt sleep

High levels of air pollution over time may get in the way of a good night’s sleep, according to new research. Source

Untreated sleep apnea in children can harm brain cells tied to cognition and mood

A study comparing children 7 to 11 years old with moderate or severe obstructive sleep apnea to children the same age who slept normally found significant reductions of gray matter — brain cells crucial to most cognitive tasks — in several regions of the brains of children with sleep apnea. The finding points to connections between this common sleep disturbance and the loss of neurons or delayed neuronal growth in the developing brain. Source

Link between sleep, cognitive impairment in the elderly

Daytime sleepiness is very common in the elderly with prevalence rates of up to 50 percent. Caused by sleep-disordered breathing (SDB), a disruption of normal breathing during sleep, these cause recurrent awakenings and subsequent excessive daytime sleepiness. Now a researcher stresses that it is time for physicians to consider the association between these sleep conditions and cognitive impairment in the elderly. Source

Evidence insufficient regarding screening for obstructive sleep apnea

The current evidence is insufficient to assess the balance of benefits and harms of screening for obstructive sleep apnea in asymptomatic adults (including adults with unrecognized symptoms), the US Preventive Services Task Force has concluded. Source

Regulating gasotransmitters could improve care for sleep apnea

Unbalanced signaling by two molecules that regulate breathing leads to sleep apnea in mice and rats. Injection of a substance that reduces production of one of those signals can prevent apneas. This approach may help people suffering from multiple forms of sleep-disordered breathing. Source

Targeted therapy for sleep disorders helps patients with muscular dystrophy

Myotonic dystrophy type 1 (DM1) is the most common adult muscular dystrophy, and many patients with DM1 suffer from various sleep and respiratory disorders. In a new study, researchers found that because there is wide range of sleep problems, treatments do not fit a “one size fits all” model. Source

Sleep apnea immediately compromises blood pressure

A single bout of sleep apnea impacts the human body’s ability to regulate blood pressure, say researchers. Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. The condition can result in frequent periods of decreased oxygen levels in the body, known as intermittent hypoxia. Source
