A new study from Iowa State University, US, suggests that singing may have certain benefits for people suffering from Parkinson’s disease. These benefits include improving motor function and a reduction of stress.
For the study, the researchers measured heart rate, blood pressure and cortisol levels in 17 participants with the condition before the one-hour singing session.
Study leader Elizabeth Stegemöller, an assistant professor of kinesiology, explains: “We see the improvement every week when they leave a singing group. It’s almost like they have a little pep in their step. We know they’re feeling better and their mood is elevated. Some of the symptoms that are improving, such as finger tapping and the gait, don’t always readily respond to medication, but with singing, they’re improving.”
New Japanese research finds that linalool, a fragrant compound in lavender, can help lessen anxiety by stimulating the nose to pass signals to the brain, not by being absorbed into the bloodstream through the lungs.
World Health Organization (WHO), as of 2015, estimates that 3.6 percent of the global population suffers from anxiety disorders. The number varies from country to country.
Study co-author Dr. Hideki Kashiwadani, of the Graduate School of Medical and Dental Sciences at Kagoshima University, says: “Our study also opens the possibility that relaxation seen in mice fed or injected with linalool could, in fact, be due to the smell of the compound emitted in their exhale breath.”
Nowadays, everyone knows what protein is but only a few of us know for sure how much of it we need to consume. According to government guidelines, average protein consumption should be 0.8g per kilogram of body weight. The next seven signs show you’re not getting enough protein, according to British nutritionists May Simpkin and Rick Hay:
A new research from neuroscientists at UC San Francisco and the Columbia University Irving Medical Center suggests that feeling of anxiety might be connected to the newly identified anxiety cell in the brain. The study was published in Neuron.
The researchers discovered this type of cells in the hippocampus in the brains of mice. The authors of the study believe that these cells also exist in human brains.
One of the senior investigators Rene Hen, Ph.D., a professor of psychiatry at CUIMC, explains: “We call these anxiety cells because they only fire when the animals are in places that are innately frightening to them. For a mouse, that’s an open area where they’re more exposed to predators, or an elevated platform.”
A new study from the University of England finds that exercising in groups reduces stress levels and improves quality of life significantly more than solo workouts.
In the course of the study, the researchers discovered that exercising in a group may reduce stress by 26% in some people compared to those who prefer exercising alone.
Dr. Dayna Yorks of the University of New England College of Osteopathic Medicine says: “The communal benefits of coming together with friends and colleagues and doing something difficult, while encouraging one another, pays dividends beyond exercising alone. The findings support the concept of a mental, physical and emotional approach to health that is necessary for student doctors and physicians.”
