We have a culture of working long hours - there's almost an unofficial competition as to who can work the most hours, get in first and leave last.
In some organisations there's undue pressure to be seen to be working at all times or your job could be at risk - that means either skipping lunch or eating it at your desk.
One in thirty feel under pressure to eat their lunch at their desk or feel self-conscious if they go out for lunch.
We all need to take more breaks during the day. It doesn't take research to realise that sitting at your desk all day is bad for you. Not only will your posture suffer but keeping still for long periods doesn't help the circulation or concentration.
Take a break from your desk - try a change of scenery and preferably get out and get some fresh air. If you have the option of getting some exercise - then do so, even if it's just a walk around the block.
Eat - and take time to savour what you're eating rather than grabbing a hasty sandwich and dashing back to your desk or skipping lunch completely.
Don't feel guilty. You're entitled to regular breaks in your working day.
You'll be more productive the more breaks you take. The longer you work on one particular task, the less effective you're likely to be.
A happier, healthier and more productive workforce take fewer days off sick and staff turnover reduces, so it benefits the company and reduces costs.
