While complete darkness is often recommended for optimal sleep, the reality is that a strategically placed night light can offer several benefits during the night. Far from disrupting sleep for everyone, a subtle night light can enhance safety, reduce anxiety, and even improve sleep quality for certain individuals. Understanding the advantages of using a light can help you determine if it’s a beneficial addition to your bedroom environment.

According to a study published in the Journal of Environmental Psychology on 1st May 2025, a dim light can significantly reduce the fear of falling and improve spatial orientation during nighttime trips to the bathroom. This is particularly relevant for children and older adults who may be more prone to accidents in the dark. The soft illumination provided by a light allows for better visibility without the disruptive effects of bright overhead lights. Furthermore, for individuals who experience mild anxiety or discomfort in complete darkness, a night light can provide a sense of security and comfort, potentially leading to a more relaxed state conducive to sleep.

Dr. Eleanor Vance, a sleep specialist at the Sleep Disorders Centre in London, in an interview on 2nd May 2025, clarified that the key to a beneficial night light lies in its characteristics. “The ideal night light should emit a soft, warm-toned light (amber or red hues are preferable as they have less impact on melatonin production) and be positioned low to the ground to minimize light exposure to the eyes while lying in bed. Bright, blue-toned lights should be avoided as they can suppress melatonin and interfere with the body’s natural sleep-wake cycle,” she advised.

Moreover, a night light can be particularly helpful for parents navigating their child’s room at night for feeding or comfort, or for individuals with medical conditions requiring nighttime navigation. The gentle illumination allows for movement without fully waking the individual or their partner. In conclusion, when chosen and used thoughtfully, a night light is not detrimental to sleep and can indeed offer practical benefits related to safety and comfort during the night. The key is to opt for a dim, warm-toned light source positioned appropriately to create a soothing and safe nighttime environment.
