It's easy to switch into autopilot mode when you're at work. Connecting with your five senses can bring you back to the present, and you can do this through "mindful eating".
Whenever you drink or eat something, give all your attention to it. Take a look at it, then close your eyes and breathe in its aroma. Notice how it feels in your mouth, and travelling down to your stomach. If you're chewing, listen to the sounds your jaw is making. Savour the taste.
This will put you firmly in the moment, increase your pleasure, and give you a momentary break from focusing on work.
