WE'RE OFTEN TOLD THAT 10,000 STEPS IS THE gold standard for keeping healthy, but where did this number come from-and is it accurate? There's no doubt that boosting your daily exercise levels by walking more brings benefits for your body and mind, experts say.

"Increasing physical activity such as your step count through walking contributes to improved cardiovascular fitness, weight management, improved mood, better sleep and enhanced cognitive function," Lindsay Bottoms, a reader in exercise and health physiology at the University of Hertfordshire in the U.K., told Newsweek. "Walking can reduce the risk of developing chronic illnesses such as dementia, and certain cancers. In some cases, it helps improve health conditions such as Type 2 diabetes." But do we need to hit a certain number of steps daily to reap these health rewards? 

Where the Target Came From

"The 10,000-steps-a-day target seems to have come about from a trade name pedometer sold in 1965 by Yamasa Clock in Japan," Bottoms said. "The device was called 'Manpo-kei,' which translates to $10,000 steps meter.' This was a marketing tool for the device and has seemed to have stuck across the world as the daily step target."

Is It Enough...or Too Much?
