Exercise thwarts high blood pressure.

For people with high blood pressure, exercise can be the most important lifestyle change they can make, researchers say. Yet two-thirds of doctors don’t take the time to tell their patients with high blood pressure about the importance of exercise and physical activity, a new study finds. “Patients do follow physician recommendations to exercise when instructed to, and patients who follow exercise recommendations tend to have lower systolic blood pressures than those who do not,” lead researcher Dr. Josiah Halm, a hypertension specialist at the University of Wisconsin School of Medicine and Public Health, told HealthDay. The findings are published in the summer issue of Ethnicity & Disease. For the study, Halm’s team collected data on 17,474 people who participated in the Third National Health and Nutrition Examination Survey. Among these people, 4,686 reported having high blood pressure. The researchers found that only slightly more than one-third of the people with high blood pressure said their doctor had told them to increase physical activity as a way of bringing down their blood pressure. Yet, 71 percent of patients with high blood pressure saw a drop in their blood pressure when they increased their physical activity, which means that they listened when doctors told them to exercise more, according to the report. “Non-pharmacological methods, such as exercising, are important in improving blood pressure control on a population level as this study looked at the cross-section of the U.S. population,” Halm said.

Black Americans need more sun.

There is a growing body of scientific and medical research suggesting that concerns about skin cancer may have been exaggerated and that most Americans, especially African Americans, actually need greater exposure to sunshine and the valuable vitamin D it helps to produce, reports EURWeb. The most recent in a series of studies was released on Tuesday by the prestigious Johns Hopkins University in Baltimore. The researchers used data from the Third National Health and Nutrition Examination Survey to conclude that not getting enough of the so-called “sunshine vitamin” appears to increase the risk of an early death by as much as 26 percent. Johns Hopkins cardiologist Dr. Erin Michos said low levels of vitamin D appear to “confer an increased risk of dying from any cause.” For African Americans, Jean Mayer of the Human Nutrition Research Center on Aging at Tufts University in Boston concluded in an earlier report: “Vitamin D insufficiency is more prevalent,” especially for Blacks living in the North. “Most young, healthy Blacks to not achieve optimal” levels of vitamin D from sunshine,” he says. That’s mostly because the natural pigment protection African Americans have against harmful ultra-violet rays reduces vitamin D absorption in North American environments, researchers say.  Studies show the sunshine vitamin offers a broad range of health benefits including boosting bone and muscle strength to offering protection against both cancer and diabetes. But Michos said more clinical studies were needed before that conclusion could be definitively made. Meanwhile, in 2007 a team from Creighton University in Omaha, Neb., found that the lower the levels of vitamin D in a woman’s body the greater is the risk of her developing breast cancer.
