Trouble falling or staying asleep isn't just exhausting—it can harm long-term health. Insomnia increases the risk of depression, dementia, and heart disease, making effective, accessible treatments essential. A recent study found that people who practiced yoga increased their total sleep time by nearly two hours compared to those receiving usual care. In a systematic review and network meta-analysis, researchers analyzed 22 randomized controlled trials involving 1,348 adults with insomnia. They compared 13 different exercise interventions—including yoga, Tai Chi, walking or jogging, and streng... exercise sleep
Read moreEarly-life nutrition influences lifelong health, and excessive calorie intake in infancy can set the stage for obesity, insulin resistance, and chronic inflammation. However, okra, a vegetable rich in anti-inflammatory and antioxidant compounds, may help counteract these harmful effects. A recent study found that rats overfed during infancy became obese and glucose intolerant, but those fed an okra-enriched diet avoided these issues entirely. Researchers raised a group of rat pups in small litters, where each pup had greater access to milk, and another group in normal-sized litters. After wean... diet inflammation insulin resistance nutrition obesity
Read moreCognitive decline—especially among older adults with dementia—can profoundly affect a person’s quality of life and increase their dependency on others. Evidence suggests that environmental exposures influence the risk of dementia. A recent study found that certain household chemicals, widely used for personal hygiene, cleaning, and disinfecting, may pose an unexpected risk for cognitive decline** in older adults. Researchers analyzed data from a large cohort study of adults over 65. They evaluated how frequently the participants used eight common household chemicals, including insecticides, ai... brain aging dementia pollution dental
Read moreFlame retardants commonly used in electronics carry considerable health risks, from carcinogenicity to endocrine disruption. Despite their harmful effects, these chemicals are often recycled into household items, including kitchen utensils, toys, and food packaging. A recent study found that black plastic household products may contain flame retardants, particularly those derived from recycled electronic products. Researchers screened 203 black plastic household products for bromine, a compound used in many flame retardants. They further analyzed products with bromine concentrations higher tha... cancer pollution
Read moreThe blood-brain barrier is a complex set of membranes that allows nutrients and cell signals from the bloodstream to enter the brain while excluding harmful substances. Obesity alters the blood-brain barrier's integrity, eliciting a cascade of adverse effects that influence many aspects of human health. This review describes the mechanisms that drive obesity-induced blood-brain barrier degradation and its effects. ... brain obesity blood-brain barrier
Read moreThe physical stress of marathon running can promote exercise-induced muscle damage, reducing muscle force production, elevating blood cytokines, and driving systemic inflammation. Consequently, despite having high cardiorespiratory and neuromuscular fitness, marathon runners are susceptible to lower extremity muscle injuries, cardiac dysfunction, and arrhythmia, particularly as running intensity escalates. A recent study shows that supplemental omega-3 fatty acids ameliorate some of the harmful effects of endurance running. The study involved 24 male long-distance runners. Half of the runners ... exercise heart disease omega-3 inflammation muscle
Read moreSedentary behavior, whether during leisure time or work, increases a person's risk for chronic disease and premature death. "Exercise snacks" – brief periods of intense exercise conducted throughout the day – may counter some of the harmful effects of sedentary behavior. This review describes the science supporting the use of exercise snacks to bolster cardiorespiratory fitness in sedentary adults. ... exercise metabolism mortality cardiovascular exercise snacks
Read moreEnvironmental exposures influence the integrity of the blood-testis barrier. Biological barriers play important roles in protecting tissues and organs from harmful environmental exposures. Examples of such barriers are found in the brain, retina, placenta, skin, and testes. Authors of a 2021 review describe the blood-testis barrier and enumerate compounds that may influence the barrier's health and function. The blood-testis barrier is composed of Sertoli cells, a type of epithelial cell that provides support to the seminiferous tubules, the site of spermatogenesis. Sertoli cells are polar...
