15-minute daily exercise is 'bare minimum for health'
Just 15 minutes of exercise a day can boost life expectancy by three years and cut death risk by 14%, research from Taiwan suggests. Experts in The Lancet say this is the least amount of activity an adult can do to gain any health benefit. This is about half the quantity currently recommended in the UK. Meanwhile, work in the British Journal of Sports Medicine suggests a couch potato lifestyle with six hours of TV a day cuts lifespan by five years. The UK government recently updated its exercise advice to have a more flexible approach, recommending adults get 150 minutes of activity a week. This could be a couple of 10-minute bouts of activity every day or 30-minute exercise sessions, five times a week, for example. Experts say this advice still stands, but that a minimum of 15 minutes a day is a good place to start for those who currently do little or no exercise. The Lancet study, based on a review of more than 400,000 people in Taiwan, showed 15 minutes per day or 90 minutes per week of moderate exercise, such as brisk walking, can add three years to your life
