Research based on a Taiwanese survey of nearly 40,000 people found that better-educated women experience better nighttime sleep, whereas higher education is associated with poorer sleep in men. Social factors such as unemployment, single parenthood, and sex discrimination contribute to these differences.
A survey of 1908 participants with gastroesophageal reflux disease (GERD) in Europe and the US found that nearly half experience sleep problems, impacting work and personal lives. The study suggests that GERD symptoms can be related to other health conditions like depression and anxiety.

A recent study by Fred W. Turek and Joseph Bass found a possible link between sleep disturbances and metabolic syndrome in mutant mice. The research suggests that altered circadian rhythms and hormone regulation, including leptin and ghrelin, may play a role in the development of obesity, diabetes, and cardiovascular disease.
Researchers used a new brain-mapping technique to study the neural connections involved in sleep regulation. The study found that neurons producing orexin, which helps keep animals awake, receive inhibitory signals from sleep-active neurons and reinforcing signals from wakefulness-activated neurons.
A recent study conducted in Norway found that bright Arctic light can trigger migraines in women with aura. The research revealed that nearly half of those with migraine with aura experienced more frequent attacks during the summer light season than during the polar winter season.
A new study published in Arthritis & Rheumatism found that Pfizer's Lyrica significantly reduced pain and improved sleep, fatigue, and other symptoms in patients with fibromyalgia. The study also showed a clinically meaningful reduction of pain in 48% of patients taking Lyrica compared to 27% on placebo.

The research found that individuals with untreated insomnia were 90% more likely to fall, compared to those taking sleep medications. Effective treatment of insomnia can help reduce the risk of falls.
Researchers found that listening to soft music before bedtime improved sleep quality and reduced daytime dysfunction in older adults. The study, published in the Journal of Advanced Nursing, used a technique where participants chose from six tapes featuring soft music and reported significant improvements in overall sleep quality.
A genetic mutation in a previously unknown circadian rhythm gene causes Familial Advanced Sleep Phase Syndrome (FASPS), shifting people's sleep times and daily schedules. Affected individuals live normal lives, but some struggle with being out of sync with the world.
A recent UCSF study has identified a genetic mutation in the casein kinase1 delta (CK1 delta) gene that is associated with familial advanced sleep phase syndrome (FASPS), a rare sleep disorder. The research, published in Nature, also suggests that circadian rhythm variants may contribute to psychiatric disorders such as depression.
Patients with obstructive sleep apnea are at much higher risk of cardiac death during sleep, with peaks occurring between 10pm and 6am. The general population's lowest risk period is actually the most vulnerable time for those without sleep apnea.
