Reducing noise is part of providing a comfortable environment. Many hospitals have reduced overhead paging systems, provided carpeted hallways, and chosen sound-absorbing construction materials to moderate noise and reduce stress. Color is also important in healthcare design. Research shows that warm and somewhat muted colors reduce stress. Natural wood and sunlight are used to depict warmth.

The hospital's wayfinding program operates both outside and in. A Matter of Taste Hospital patients surveyed by the Journal of the American Dietetic Association felt that the smell, taste, and appearance of their food had a profound effect on their wellness. Some hospitals have a kitchen near the patient rooms, where fresh-baked cookies and breads are served to patients and visitors. This provides a homelike aroma and eliminates the antiseptic odor. Zale Lipshy University Hospital in Dallas, has taken this theory to heart.
