https://medicalxpress.com/sleep-news/ en-us Latest health news and information about Sleep & Recovery Why are conditions such as chronic stress, depression, cardiovascular disease, fragmented sleep, and aging all associated with a higher risk of dementia? In a new review piece in Science, University of Rochester Medicine neuroscientist Maiken Nedergaard, MD, DMSc, proposes that many of these seemingly different conditions may converge on the same biological problem: disruption of a sleep-dependent brain rhythm that helps clear waste from the brain. https://medicalxpress.com/news/2026-05-brain-night-shift-clearance-dementia.html Thu, 21 May 2026 14:00:12 EDT news698571481 High-resolution data collected across the United States show negligible evidence of adverse health outcomes tied to wind turbine exposure, a study finds. Despite helping to reduce greenhouse gas emissions, wind turbine installations have raised concerns about potential health effects, particularly from infrasound and low-frequency noise emissions. However, the evidence, often based on small samples or self-reported symptoms, remains inconclusive. https://medicalxpress.com/news/2026-05-human-health-unaffected-turbines.html Wed, 20 May 2026 12:20:10 EDT news698497562 A once-nightly oral pill helped control obstructive sleep apnea in a large, Phase III clinical trial presented at the 2026 ATS International Conference. The drug, called AD109, is the first therapy to treat OSA by addressing its underlying mechanisms and targeting the neuromuscular causes of airway collapse. https://medicalxpress.com/news/2026-05-nightly-pill-airway-collapse-obstructive.html Mon, 18 May 2026 07:00:03 EDT news698052901 A healthy brain may help protect thinking and memory skills from the early effects of Alzheimer's disease, a new study has found. Dementia is currently the leading cause of death in Australia and Alzheimer's disease is its most common form—accounting for more than 70% of cases. https://medicalxpress.com/news/2026-05-brain-health-linked-resilience-early.html Fri, 15 May 2026 09:37:19 EDT news698056562 Northwestern University engineers have developed a small, wireless polygraph system you can wear. Unlike polygraphs used in television crime dramas, this wearable version isn't optimized to detect lies. Instead, engineers and physicians designed it to sense underlying stress hidden deep within the body—no interrogation room required. https://medicalxpress.com/news/2026-05-wearable-polygraph-tracks-hidden-stress.html Wed, 13 May 2026 14:00:07 EDT news697824781 An analysis of biological clocks throughout the human body suggests that too few hours of sleep—and too many—may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases. https://medicalxpress.com/news/2026-05-faster-aging.html Wed, 13 May 2026 11:00:17 EDT news697883187 People often describe anesthesia as something that puts a patient in a "deep sleep." An anesthesiologist enters the operating room, and part of their mission is to ensure that the patient is completely unaware of what is happening around them until they wake up, often several hours later. Scientists and doctors have long debated what happens to the brain under anesthetic drugs during a surgical procedure. https://medicalxpress.com/news/2026-05-deep-anesthesia-brain-strange-state.html Wed, 13 May 2026 08:37:48 EDT news697880221 New research from the University of Minnesota School of Public Health shows that teenagers today are getting less sleep than any generation before them. This lack of sleep causes daily fatigue and reduced functioning, alongside long-term health concerns including poor mental health, academic difficulties and chronic disease later in life. https://medicalxpress.com/news/2026-05-today-teens.html Tue, 12 May 2026 12:20:01 EDT news697806362 Humans and other mammals cycle through distinct sleep phases. One of them is easily recognized by the darting motion of the eyes behind closed lids, giving it its name: REM (rapid eye movement) sleep. This is the state in which we experience our most vivid, intense dreams. https://medicalxpress.com/news/2026-05-fish-reveal-distinct-states-eye.html Wed, 06 May 2026 14:00:06 EDT news697287301 Being an early bird or a night owl may be defined by your genetics, but Pitt research published March 16 in The Journal of Physiology suggests that those who rise early may receive some protection against conditions such as type 2 diabetes in return. https://medicalxpress.com/news/2026-04-heart-rhythms-reveal-early-bird.html Tue, 21 Apr 2026 17:40:03 EDT news695996577
