The night lights were once considered by many a miracle. Who can explain such an effect? But since then, scientists have found that night lights can have more profound effects than just creating a romantic atmosphere. Night lights can provide a sense of security, especially for children. In addition to providing illumination, night lights also provide a sense of safety to children in unfamiliar and sometimes scary environments. A night light helps a child to orient him or herself and to discover information during the night. It also helps keep nightmares away. Moreover, night lights can help alleviate the problems commonly associated with irregular bedtimes, such as school performance or insomnia. Although the jury is still out on this, recent studies have suggested that a night light can improve a child's sleep cycles by providing enough light to keep the child from becoming overly exhausted during nighttime hours. Finally, night lights could provide vital warning signals in the event of a fire or other emergency. Night lights can also deter burglars, as they typically don't like to lurk in the shadows. Ultimately, night lights are more than just a novelty. They can help provide a sense of comfort and safety for children. Their effects also go beyond the teenage years, making getting a good night's sleep easier for adults, as well.
