Night lights have been around since ancient times. In the past, people used candles and oil lamps to light their homes at night. Today, the night lights have evolved into various forms, from regular lights to energy saving LED lights. Night lights provide a soft, comforting and reassuring atmosphere to any dark room. Many parents install night lights in childrens bedrooms for practical reasons. They are perfect for making them feel secure when they are suddenly awakened in the night, or for providing just enough light to make downstairs trips to the restroom a bit easier. In addition, the lights provide safety for children, serving as a deterrent to possible intruders who might try to break in. Night lights can also serve as mood lifters. To those who are having difficulty sleeping due to depression or anxiety, night lights can be a great way to calm down and make their bedroom more inviting. Having a nightlight in the room helps to keep away feelings of loneliness and fear in the dark. Night lights also have many practical uses. They are ideal for late-night snacking, helping you see where to place the food youre looking for in the pantry. They also make it easier to look for something youve misplaced while cleaning. Whether its for safety or utility reasons, the night light is a staple in any home.
