Night lights have been around for centuries. They have been used to light up shadowy streets and create a feeling of safety in homes. However, they also have a more beneficial purpose beyond this. Night lights can help to affect the quality and duration of sleep. Studies have shown that even the smallest amount of light in a dark room can affect the sleep of a person. Light has the tendency to reduce the amount of deep sleep and increase the amount of light sleep. Furthermore, sleeping in a completely dark room helps people rest more easily and have an overall more restful sleep experience. Thus, the presence of a night light provides a subtle amount of light without causing too much disturbance of sleep. A dim light source like a night light can reduce night time awakenings caused by fear of the dark, help children to adjust to sleep in their own rooms and encourage night breastfeeding in case of infants. Whether you require a night light for safety purposes or for helping to ensure a good nights sleep, they are a helpful addition to many homes. They can provide a subtle but significant amount of light and can be a comforting companion for those who are scared of the dark.
