Dim night lights and warmer colors are best for children. Results of a small 2018 study suggest that exposure to blue and yellow LED lighting at night affects children more than adults. They can also be practical for children who wake up at the night and want to be able to go to another room. Options with timers can be useful for children who enjoy reading in bed before falling asleep. Night lights may help children feel calm and comfortable, which could allow them to doze off easily and sleep deeply. They may help children who are afraid of the dark to feel relaxed and at ease overnight. Blue and yellow LED lighting can suppress the production of melatonin — the main hormone that regulates your sleep-wake cycle — and reduce tiredness throughout the night in children, which may negatively affect sleep quality. When should I give my child a night light? You can give your child a night light at any age, but you’ll want to pay attention to any safety features that may make specific models more or less suitable for infants and toddlers. For example, you might want to steer clear of night lights with battery compartments that are easy to open. Are there any benefits to night lights for kids?
