Night lights have a pervasive effect on many of us. In our hectic lives, they often signal the end of the day and create a peaceful atmosphere that is conducive to relaxation. Although night lights often invoke feelings of security and nostalgia, they can also be an important security feature. By providing a source of illumination in a dark room or hallway, they can alert us to any potential trespassers. Many people even use them in the bathrooms and bedrooms to ensure there are no surprises in the middle of the night. Additionally, night lights can provide a source of either comfort and/or information which can help us better regulate our circadian rhythms. For example, you may be able to determine the time of day simply by glancing at the night light. Additionally, if you are dealing with insomnia, then a night light may be the perfect way to ensure that you are not disturbed by complete darkness while trying to rest. In conclusion, night lights come in a variety of forms and offer many useful and important benefits. From providing needed safety to helping us better regulate our sleep cycles, they are an invaluable tool in any home-dwellers arsenal. Whether you are looking to create a cozy atmosphere, to protect your home, or to help you rest better, there is no doubt that night lights can provide a helpful service.
