These changes can be applied to any room in the house. Start with the floor. If you don't have a carpet, add a throw rug that is soft to the touch. Don't use bright lights in the room. Use soft, small lamps or a floor lamp.
Low lighting makes the room cozier.
When decorating the room, use soft, pale colors, such as pastels to keep the mood calm. If you want to add bright colors, use them as accessories, such as pillows or on the throw rug. To add space to the room and open it up, hang a mirror on the wall or add a floor mirror in the room. Have nature sounds, such as the ocean or rain playing in the room. Water is supposed to be a symbol of positive energy.
