Low Level Physical Activity Benefits Knee Osteoarthritis

It’s well known that increasing the time spent doing moderate intensity physical activities has wide ranging benefits on health. Guidelines recommend 150 minutes a week of moderate to vigorous physical activity. What about those unable to engage in moderate or vigorous physical activities due to health issues? Could light physical activity work too?

A study by professor Dunlop et al. looked at the effects of physical activity in people with knee osteoarthritis or risk factors for knee osteoarthritis. As well as finding benefits to moderate activity, they found that spending more time doing light intensity physical activities reduced the risk of onset and progression of disability due to osteoarthritis. They concluded that “an increase in daily physical activity time may reduce the risk of disability, even if the intensity of that additional activity is not increased.”

Breathing Exercises Help Treat PTSD

A study by Seppala et al, published in last month’s issue of the Journal of Traumatic Stress, looked into the effects of yogic breathing on war veterans with post traumatic stress disorders (PTSD). They found that after the course of controlled breathing exercises the test subjects had reductions in PTSD scores, anxiety symptoms, respiration rate, startle signs and other hyperarousal symptoms. The benefits were still present 1 year later. It’s thought that the breathing exercises help balance the autonomic nervous system.
