Minority and Low-Income Sleep Gap May Be Tied to Disproportionately Higher Disease Prevalence
Sleep Review

Minority and low-income communities face a sleep gap that could potentially be driving higher disease prevalence, according to a journal article in The Lancet Neurology.  Lead author Girardin Jean-Louis, PhD, addresses how sleep disparities may impact health in minority communities. People in these groups face higher risks of cardiovascular disease, diabetes, high blood pressure, and other chronic conditions, and lack of sleep may help drive these disparities. “Black and Latino people in the US sleep around 30 to 60 minutes less [per night] than white people,” says Jean-Louis, who directs ..read more

Students sometimes pull an all-nighter to prepare for an exam, but research has shown that sleep deprivation is bad for your memory. However, University of Groningen neuroscientist Robbert Havekes, PhD, has discovered that what you learn while being sleep deprived is not necessarily lost; it’s just difficult to recall.  Together with his team, Havekes found a way to make this “hidden knowledge” accessible again days after studying while sleep-deprived using optogenetic approaches and the human-approved asthma drug roflumilast.  The study, published on Dec. 27 in the journal Current B ..read more

Sleep Apnea Tied to Low Bone Mineral Density
Sleep Review
by Alyx Arnett
6d ago
Obstructive sleep apnea (OSA) may be linked to low bone mineral density in adults, which could have implications for orthodontic treatment, according to a study led by University at Buffalo researchers. The study was published in November in The Journal of Craniomandibular and Sleep Practice. The findings are crucial for individuals with sleep apnea, as low bone mineral density is an indicator of osteoporosis. In addition to increasing the risk of fractures, low bone mineral density also impacts oral health, causing teeth to become loose and dental implants to fail, according to senior author ..read more
