Keep your desk tidy ~ If you are anything like me my desk tends to get untidy at some point throughout the day, but I always take the time at the end of the day to neaten up and place items in their designated places.
Take enough breaks ~ take the time to stand and stretch and walk away from the computer screen to rest your eyes.
Get outside ~ sit outside and enjoy the sunshine. Make some time for you by flicking through a magazine, reading a chapter from the book you are reading. Catch some vitamin D which is important for the health of your bones.
Take time to eat and enjoy your lunch ~ Just like working outside the home you need to allocate time for lunch. Are one of those people that eat lunch while working? I do sometimes but I always try to eat lunch away from the office. Make yourself something healthy to get you through the afternoon.
