A new study shows that too many people are working at for from in o of off on over through to their lunch hour. Not taking a proper lunch break is unhealthy. It can make people sick, so then they need time at for from in o of off on over through to work. The study is at for from in o of off on over through to the Chartered Society at for from in o of off on over through to Physiotherapy (CSP) in the U.K. It interviewed at for from in o of off on over through to 2,000 people about what they do at for from in o of off on over through to lunch at work. Twenty per cent of the workers said they did not take a lunch break. They worked through their lunch hour. Half at for from in o of off on over through to the people took a break but ate their lunch at for from in o of off on over through to their desk and surfed the Internet, answered e-mails or went at for from in o of off on over through to Facebook. One in five people left the workplace at for from in o of off on over through to lunch to go shopping or get some air, while three per cent went at for from in o of off on over through to the gym. The CSP told companies they should encourage all staff to take a regular lunch break. It said workers needed to get more exercise at for from in o of off on over through to work so they do not get ill. CSP spokeswoman Karen Middleton said: "Full-time workers spend a significant bulk at for from in o of off on over through to their week at for from in o of off on over through to work or travelling at for from in o of off on over through to and at for from in o of off on over through to it. Finding ways to build in time to do at for from in o of off on over through to least 30 minutes of moderate intensity physical activity, five times a week, can be a challenge." She warned that when employees get sick because they do not take breaks, companies lose money. She said: "It is at for from in o of off on over through to everybody's interests to find ways to tackle the enormous problem at for from in o of off on over through to f inactivity…and we would encourage people to take responsibility at for from in o of off on over through to their own health."
