How Exercise Helps Your Heart

How Exercise Helps Your HeartTUESDAY, May 22, 2018 (HealthDay News) -- You already know that exercise is good for your health and your heart, both to prevent heart disease and, for those who already have a heart-related condition, to make managing it easier. But you might be even more motivated to work out if you better understand exactly how exercise helps. Studies have found two important benefits from exercise. First, it improves cardiorespiratory fitness, or CRF. That's the capacity of both your heart and your lungs to provide muscles with oxygen. It's an excellent indicator of how much you exercise, and is used as a diagnostic tool and even a predictor of future health. Your doctor can order a test to measure your CRF. It typically involves doing a treadmill workout while key vital signs are monitored and...

Commuters: Pedal Your Way to Better Heart HealthTUESDAY, May 22, 2018 (HealthDay News) -- Ditching the car and biking or walking to work just might cut your risk of developing heart disease and even dying from it. So says a new British study that finds a person's risk of heart disease or stroke falls 11 percent and their risk of dying from these diseases falls by 30 percent, just by exercising on their way to work. "Walking, cycling and even using public transport are all more physically active than using the car, so switching to one of these modes of transport can help you be more active and healthy," said researcher Oliver Mytton. He's a clinical lecturer in public health at the University of Cambridge. But Mytton cautioned that this study didn't prove that a physically active commute will lower your risk of heart disease or...

Lifelong Exercise Can Guard Heart Health

Lifelong Exercise Can Guard Heart HealthMONDAY, May 21, 2018 (HealthDay News) -- Exercising may keep you young at heart. Researchers found that people who make regular exercise a lifelong habit appear to slow the aging of their heart and blood vessels. The finding stems from a comparison of exercise histories and heart health among 102 people over age 60. Those who had exercised two to three times a week for at least a half-hour a day for many years had more "youthful" -- that is, less stiff -- middle-sized arteries, the researchers found. Middle-sized arteries supply oxygen to the head and the neck. But study participants who had routinely exercised four to five times per week had more youthful large, central arteries, ones critical to providing blood to the chest and abdomen. "This work is really exciting because it...

Start Exercising to Cut Your Heart Failure Risk

Start Exercising to Cut Your Heart Failure RiskFRIDAY, May 18, 2018 (HealthDay News) -- Attention, middle-age couch potatoes: There's still time to lower your risk of heart failure, a condition affecting more than 5 million Americans. Getting the recommended 150 minutes a week of moderate physical activity can reduce your risk in just six years, according to new research from Johns Hopkins University School of Medicine. On the flip side, as little as six years of sedentary living increases your odds for the condition, which is the leading cause of hospitalization in people over age 65. "In everyday terms our findings suggest that consistently participating in the recommended 150 minutes of moderate to vigorous activity each week, such as brisk walking or biking, in middle age may be enough to reduce your heart failure risk by...

Pools, Hot Tubs Can Harbor Dangerous Germs

Pools, Hot Tubs Can Harbor Dangerous GermsTHURSDAY, May 17, 2018 (HealthDay News) -- Pools, hot tubs and water playgrounds may be synonymous with summertime fun, but they also can be breeding grounds for dangerous germs that could make you violently ill. In some cases, they can even lead to death, U.S. health officials reported Thursday. And of all the outbreaks from waterborne germs between 2000 and 2014, one-third occurred in pools or hot tubs at hotels, the officials said. "We often underestimate what it takes to properly run a pool or hot tub to maintain a chlorine level where it needs to be," said study lead author Michele Hlavsa, chief of the U.S. Centers for Disease Control and Prevention's Healthy Swimming Program. That's why the CDC recommends that public pools -- including hotel pools and water parks -- be run by...
