We have all heard that we should walk 10,000 steps per day, but to improve our health, we don’t even need to walk that much. In a new study published in the journal Nature Medicine, researchers at Vanderbilt University had over 6,000 participants over the age of 40 wear activity trackers at least 10 hours a day. They then analyzed data from the participants medical records for years. They found that people can improve their health in many ways by walking and moving more. Diabetes, sleep apnea, high blood pressure, diabetes, depression, and reflux showed benefit to getting more steps in, usually around 8,000 to 9,000 per day. Overweight participants who walked 11,000 steps per day, or just over five miles, cut their risk of developing obesity in half.
