There is one simple guideline to follow in creating a healing environment : look for ways to reduce stress in the environment. This is based on research from the field of psychoneuroimmunology that shows how emotional stress  impacts our bodies in multiple ways. It does this because our brain and our nervous, endocrine, and immune systems are constantly interacting. An impact on one system reverberates throughout the others.
Choose a private room if it is an option. Noise is a major contributor to stress and there is growing evidence that the infection rate is lower when patients are cared for in single rooms.
Here is a list of other suggestions that you can try:
Eliminate Environmental Stressors:
Work with the Staff:

You probably have more control over your work environment than at the hospital, but there will still be restrictions. 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.)
If you can choose the furniture, great. You can consider the color there, too. Often, even if you can't choose anything else, you can select your chair. If you have an ergonomics expert available, enlist help in choosing the most comfortable chair for you—otherwise do some research about the available chairs (often the web has good data).
If you can't choose your wall colors or furniture, don't worry, there are still things you can do.
Finally, consider setting a positive intention for your interactions in the space-that you will act according to your highest principles while in the office—and watch to see how it unfolds in the months after you do so.
You have the most control of your environment at home, of course, but even there you will encounter limitations-the needs and preferences of the other people in your house, the cost of making changes, the layout of the house itself.
One way to start is to choose a room or corner that you can make into a healing space. If you already have a favorite place that you can use, wonderful. If it has good natural light and a view of the outdoors, even better.
Then consider what activities you find most healing and adapt the space to them. Do you love to read? Move a comfortable chair and good light into the space. Do you meditate? Perhaps a water fountain would help you relax and focus. You might even find that your healing space is a workbench where you build or fix things, and organizing your tools and providing good light is what you need.
As with other spaces, consider your inner environment as well. Realize that optimism, hardiness, self-efficacy, and a sense of control are linked to good health and that they can be learned and practiced. Set a positive intention for your interactions in the space.
