Nature Changes Clinical Outcomes
- Seeing trees from a hospital window altered patients' recovery: less pain, happier mood, and shorter stays.
- Kathy Willis found clinical evidence across medical journals linking nature exposure to measurable health changes.
Brief Nature Views Reduce Stress
- Short visual exposures to natural scenes lower physiological stress markers like blood pressure.
- Experiments compare 90 seconds of forest images versus cityscapes to isolate nature's effect.
Plant Scents Trigger Biochemical Calm
- Specific plant compounds (e.g., pinene, limonene) produce calming biochemical responses even in infants.
- Smelling these compounds triggers measurable clinical calming unrelated to cultural memory.
