Light can do a lot more than just make things visible, especially in a tense environment. A warm, diffused glow from a well‑placed lamp can soften the corners, reduce harsh shadows, and give a patient a sense of stability. If you use a cooler hue and direct it at a relaxed angle, it helps lower the eye strain that makes people feel on edge. So yes, the right lighting can be as soothing as a good dose of medicine when you’re trying to calm a mind as well as a body.
