Pressure on different areas of the foot are proven to stimulate blood flow.
A good foot massage is loved by all, but researchers at the University of Stirling in Scotland have found that reflexology exercises on the balls of feet increased flood flow to the heart, making a foot massage a heart-healthy exercise as well.
The study found that different points of the foot act as a "map" to chart blood flow to different organs, increasing blood flow throughout the body. Many foot problems can be eased by reflexology, including osteoarthritis and bunion relief. However, most medical science research has not linked foot health to cardiovascular well-being until these tests were run. Jenny Jones, Ph.D., stated that she wanted "to research and better understand why this one area of the foot – the upper left ball of the sole – had an effect on the heart."
According to The Telegraph, practitioners mostly agree with the link between heart health and reflexology, used in extremities like the hands and feet. There were two studies done to compare those who were suffering from cardiac heart failure and coronary heart disease, both of which proved these exercises to be safe for those suffering from those ailments.
