While we often walk for heart, lung, and bone health, walking also promotes the health of our kidneys. These bean-shaped organs play a vital role in nutrient absorption and waste filtration. A walking routine keeps kidneys functioning properly and reduces risk of kidney stones, recurring urinary tract infections, and chronic conditions leading to kidney disease. When you exercise, you help your kidneys by:

• Sweating to the oldies. No matter what music accompanies your workout, physical activity causes you to perspire, which helps the kidneys eliminate toxins from your bloodstream.

• Speeding it up. Belgian researchers have found that exercise makes kidneys work faster to filter and excrete waste.

• Keeping it in check. Walking 30 minutes a day, five days a week helps maintain healthy blood pressure, cholesterol levels, and blood glucose — which affect kidney health.

A regular walking routine offers a multitude of benefits, including helping to keep your kidneys working in top form.
