Simple leg exercises can reduce negative effects on heart and blood vessels

Did you know how beneficial are simple leg exercises while lying down? A sedentary lifestyle can cause an impairment of transportation of blood in the body which in turn may increase the risk of diseases in the heart and blood vessels.

Health News:   Performing  Simple leg excercise can make a huge change and prevent such problems, a new study reveals.

Earlier work has demonstrated that prolonged sitting for up to 6 hours results in a decline in both blood flow to the limbs and in our larger arteries’ ability to widen to accommodate increased blood flow. This is the first study to show that sitting for just 10 minutes is sufficient to reduce blood flow to the legs and impairs the function of small blood vessels supplying muscles in the leg.

This paper also highlights a reduction in the function of small blood vessels when lying down. However, this study suggests that we might be able to reverse this impairment to some extent by performing some simple leg exercises when lying down in bed or on the sofa.

The effects of sitting on blood circulation have been attributed to blood passing more slowly through arteries while sitting. The researchers aimed to find out whether these reductions were caused by sustained sitting, or whether 10 minutes would be sufficient to have a negative effect.

Eyes can provide early sign of Parkinson’s disease

Turns out, eyes play a crucial role for people with Parkinson’s disease.

People with the disease gradually lose brain cells that produce dopamine, a substance that helps control movement. Now, a new study has found that the thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of such brain cells.

Study author Jee-Young Lee said, “Our study is the first to show a link between the thinning of the retina and a known sign of the progression of the disease — the loss of brain cells that produce dopamine.”

Lee added, “We also found the thinner the retina, the greater the severity of the disease. These discoveries may mean that neurologists may eventually be able to use a simple eye scan to detect Parkinson’s disease in its earliest stages before problems with movement begin.”

The study involved 49 people with an average age of 69 who have diagnosed with Parkinson’s disease an average of two years earlier but who had not yet started medication. They were compared to 54 people without the disease who were matched for age.

Researchers evaluated each study participant with a complete eye exam as well as high-resolution eye scans that use light waves to take pictures of each layer of the retina. Researchers found retina thinning, most notably in the two inner layers of the five layers of the retina, in those with Parkinson’s disease.
