High blood pressure, also known as hypertension, is blood pressure that is higher than normal. A normal blood pressure level is less than 130/80 mmHg. The rate of high blood pressure varies by sex and race. About 50% of men have high blood pressure compared to 44% of women The research compared magnetic resonance imaging […]
A new study being presented at this year’s American College of Allergy, Asthma and Immunology Annual Scientific Meeting in Louisville, KY, showed elevated levels of cat and dog allergens, as well as β-D glucans (BDG) and endotoxin on simulated phone models. “Smartphones showed elevated and variable levels of BDG and endotoxin, and cat and dog […]
Regardless of age, adults are advised to do at least 150 minutes a week of moderate intensity activity or 75 minutes a week of vigorous intensity activity, or an equivalent combination. “Our study suggests that walking at least one hour every week is beneficial for people aged 85 years and older. Put simply, walk for […]
Scientists at the Medical College of Georgia looked in the hypothalamus, key to functions like releasing hormones and regulating hunger, thirst, mood, sex drive and sleep, at a population of neurons called the proopiomelanocortin, or POMC, neurons, in response to 10 days of chronic, unpredictable stress. They found the stressors increased spontaneous firing of these […]
A new study from UCLA researchers finds sex-specific brain signals that appear to confirm that different drivers lead men and women to develop obesity. “We found differences in several of the brain’s networks associated with early life adversity, mental health quality, and the way sensory stimulation is experienced. The resulting brain signatures, based on multimodal […]
Researchers from the University of Adelaide and South Australian Health and Medical Research Institute (SAHMRI) compared two different diets: a time restricted, intermittent fasting diet and a reduced calorie diet to see which one was more beneficial for people who were prone to developing type 2 diabetes. Type 2 diabetes occurs when the body’s cells […]
“There’s a dogma in the field that everyone needs eight hours of sleep, but our work to date confirms that the amount of sleep people need differs based on genetics,” said neurologist Louis Ptacek, MD, “Think of it as analogous to height; there’s no perfect amount of height, each person is different. We’ve shown that […]
New research at the University of Massachusetts Amherst zeroes in on the root cause of adverse health effects from disruption of the body’s circadian rhythms, which typically occurs from jet lag and rotating work shifts. “Circadian disruption impacts a lot of things,” says lead author Michael Seifu Bahiru, a Ph.D. candidate in the lab of […]
Using a new way of analysing mortality records, figures from 19 high-income countries suggest that we haven’t yet approached the maximum human lifespan and could see the record start to rise in the next few decades. “We don’t appear to be approaching a maximum limit at the moment,” says the study’s lead researcher David McCarthy […]
Men with high levels of body fat have lower bone density and may be more likely to break a bone than those with normal levels of body fat, according to a new study. Health care providers often assume people with higher body weight have high bone density and are at low risk of fracture, and […]
