Night lights has a long history in many cultures. The use of candles, oil lamps and lanterns at nighttime is an ancient practice. Lighting techniques must have been developed very early in the history of human evolution. For example, the ancient Egyptians are believed to have been among the first to make and use light sources during the night. Night lights have persisted in modern times, particularly in areas with low levels of natural lighting or when there is an extended period of darkness. For example, in polar regions where days may be very short during the winter, lighting is used to keep fear and depression at bay. Night lighting can also be used to create a certain atmosphere, for example in restaurants or cafes – lighting can be used to create romantic or homely ambience. Night lighting has a number of other practical uses. For example, safety lighting can be used to lighten up dark areas or pathways. Lights also provide a means of orientation, allowing people to find their way around in the dark more easily. Notably, night lighting offers many health benefits as well. The human body has an internal clock that is largely determined by exposure to light. So, realigning our body clocks to follow the suns natural rhythms is beneficial to our overall health and well-being. Light exposure can also improve mood and reduce anxiety and depression. Night lighting can also help to ward off nocturnal predators and secure homes. In conclusion, night lighting has a long history, and has many practical benefits in both traditional and modern society. Used safely and responsibly, night lights can improve our quality of life in many ways.
