3. Provide the right light
People work most productively in daylight. In a home office, you have a say in how you choose your workspace. It should be as bright as possible, preferably near a window, so you can enjoy the daylight. At the same time, you save electricity if you can do without electric lights. During the dark hours of the day and in the evening, when you can’t do without electric light, you should switch to LED lights and replace incandescent and halogen lamps.
