Walk, work, and eat at a relaxed pace.
Take a short break after meals to relax.
If possible, go outside at least once per day and notice the simple things such as the weather, scenery, etc.
During the day, whenever you remember, notice and tension in your body (jaw, neck, diaphram, shoulders, etc.). Breath deeply and gently stretch and relax any tense areas.

Take breaks during the workday to relax.
Wear comfortable and loose clothing when possible. Take off your shoes when you can.
