If you feel you’ve been unproductive and sluggish at work, try adding some plants to your office setting. Plants are said to make indoor workplaces healthier, calmer and improve productivity. Besides enhancing office decor, plants enhance employee well-being and air quality. Studies have also shown that plants can combat ’sick building syndrome’ in which toxins from furniture, carpeting, wall coverings and other office decor are linked to ailments, ranging from upper-respiratory problems to eye irritations, allergies, colds or viruses.
