Calmness. Focus. A strong immune system. These are all benefits that come with being in nature, something usually not found in the office workspace. To spruce up an office that might otherwise be dull and sterile, a firm in Lisbon has added 1,000 plants of varying sizes to create a space that not only looks vibrant, but also helps to purify the air and dampen background noise. On top of that, research shows that such a workplace can help to improve productivity and morale. If you work at home, consider adding plants to your office to create a livelier, healthier workspace.
