You probably have less control over your work environment than at home, but there are still things you can do.
Paint your office
If you can paint the walls, great: choose a color that appeals to you.
- Consider: do you want the atmosphere to be calming or invigorating?
- Then consider which colors produce that effect in you. (Some studies show that red increases heart rate and is thought to be invigorating, while blue decreases heart rate and is thought to be calming.)
