We had 7 hours and 23 minutes of daylight today here in Denmark. It’s dark when you go to work, and it’s dark when you head home. That means it is even more important at this time of year to use your lunch break to get some light and fresh air.
Don’t just stay at your desk and just eat a sandwich. Or even worse, eat whatever is still available in the vending machine or the snack cabinet. If you don’t believe it matters, find some kind of productivity metric and track your morning and afternoon. It can simply be how much time you spend on each application on your computer. Do one week with lunch at your desk, and one with a short walk outside. Compare. You’ll find that your afternoon in the week with lunch at your desk will show way more YouTube, social media, and aimless procrastination.
