In a new study Dr. Farrah Kheradmand and their team discovered that exposure to ultrafine particles alters the function of immune cells in the lungs, disabling their natural defense mechanism against tumors. They found that ultrafine particles change the cell’s primary energy source, creating new byproducts in the lungs. Accumulation of the new byproducts can […]
A new study from the Smidt Heart Institute at Cedars-Sinai shows there is a gender gap between women and men when it comes to exercise. Investigators analyzed data from 412,413 U.S. adults utilizing the National Health Interview Survey database. Participants between the time frame of 1997 to 2019 — 55% of whom were female — […]
People who tend to view stressful situations as a threat are more likely to experience health and wellbeing problems, both mental and physical, than those who see them as a challenge, according to new research. The research explored stress appraisals, health and wellbeing of 395 sport performers through an online survey. The researchers believe the […]
A new study by researchers at University of Limerick in Ireland and at Iowa State University has demonstrated the impact resistance exercise training can have in the treatment of anxiety and depressive symptoms. The researchers said there was “exciting evidence” that resistance exercise training may be an accessible alternative therapy to improve anxiety and depression […]
Increases in symptoms of depression are associated with a subsequent increase in body weight when measured one month later, new research from the University of Cambridge has found. Research has suggested a connection between weight and mental health but the relationship is complex and remains poorly understood, particularly in relation to how changes in an […]
Scientists have identified a protein in the visual system of mice that appears to be key for stabilizing the body’s circadian rhythms by buffering the brain’s response to light. Scientists have long known that most living things have a circadian “clock,” a set of biological rhythms that operate on about a 24-hour cycle and that […]
New research indicates that the eating disorder anorexia nervosa is associated with being an early riser, unlike many other disorders that tend to be evening-based such as depression, binge eating disorder and schizophrenia. Previous research has suggested a possible connection between eating disorders and the body’s internal clock, or circadian clock, which controls a wide […]
In Finland, there is a clear increase in the number of sick days taken due to depression, anxiety and sleep disorders in October and November, whereas the number of absences is lower than expected between June and September. In late autumn, the number of sick days taken is almost twice as high as in the […]
Elevated levels of air pollutants are associated with bone damage among postmenopausal women, according to new research. The effects were most evident on the lumbar spine, with nitrous oxides twice as damaging to the area than seen with normal aging. Previous studies on individual pollutants have suggested adverse effects on bone mineral density, osteoporosis risk, […]
A new study has tabulated the toll from two decades of wildfires on air quality and human health in the continental U.S. The authors report that from 2000 to 2020, the air has worsened in the western U.S., mainly due to the increase in frequency and ferocity of wildfires causing an increase of 670 premature […]
