Night Lights are a popular phenomenon all over the world. Unlike the bright daytime sun, the night lights create an atmosphere of calm and serenity that appeals to many people. Night Lights come in a variety of shapes, sizes, and colors. Some are designed to be decorative, while others are designed to provide a practical purpose. Decorative night lights can be found in nearly any color, and can be shaped like stars, hearts, or other designs. For practical purposes, night lights are often used to provide safety and security in a room; they provide just enough light to help draw attention to doorways, stairwells, and other routes by which danger may enter a room. The relaxing effects of night lights are both psychological and physiological. Studies have shown that in dark rooms, the hearts and minds are conditioned to relax, allowing for an improved quality of sleep. This improved sleep quality leads to better physical and mental health, as well as a feeling of well-being. The popularity of night lights is well-deserved. Not only do the benefits to sleep quality and improved safety make them a valuable addition to home and office decoration, but their aesthetic beauty and calming effects make them a welcomed addition to any living space. From small, subtle night lights to large, brightly-colored decorative pieces, the night lights are sure to add a touch of beauty to any space.
