Can White Noise Help Your Baby Get Better Sleep?

How White Noise Machines Help Babies Sleep Better

White noise machines are designed to mask disruptive background sounds like conversations, traffic, or even household noises that might interrupt your baby’s sleep. But they do more than just cancel out noise—they mimic the sound environment of the womb. Inside the womb, babies are surrounded by rhythmic, continuous sounds, such as the whooshing of blood flow and the gentle thumping of the mother’s heartbeat. These familiar sounds can create a calming, secure atmosphere that helps soothe your baby, encouraging longer and deeper sleep.

For parents struggling with a fussy or overtired baby, white noise can serve as a valuable sleep aid by helping your little one relax and settle into sleep more easily. Many parents find that white noise helps establish a sleep routine, as it becomes a comforting cue signaling that it’s time for sleep.

I’ve Heard Conflicting Advice About Sound Machines—What Should I Believe?

Yes, there’s a lot of mixed advice out there! While some parents and pediatricians strongly advocate for white noise machines, others have raised concerns about their use. A widely discussed 2014 study found that some white noise machines could exceed the recommended noise level for infants in nurseries, which is set at 50 dBA. All 14 machines tested in the study were found to surpass this limit when played at their highest volume settings.

However, it’s important to remember that the key factor here is volume and proximity. White noise machines can be beneficial when used safely and correctly, much like any other baby product.

Does That Mean You Shouldn’t Use a White Noise Machine?

Not at all! Baby sleep experts agree that white noise machines can be extremely effective for helping infants sleep better, as long as they are used carefully. Here are a few safety tips to keep in mind:

  1. Positioning: Keep the machine at a safe distance from your baby’s crib—at least 7 feet away is recommended. Avoid models that attach directly to the crib.
  2. Volume Control: Ensure the machine is set to a low volume, ideally below 50 dBA. You can use a smartphone app to measure sound levels to ensure it stays within the safe range.
  3. Time Limits: Limit the exposure to white noise. Some experts suggest using the machine only for the duration of naps and nighttime sleep, rather than running it continuously.
  4. Monitoring: Periodically check the machine to ensure it’s not too loud or too close to your baby. Over time, your baby might not need white noise as much, so you can gradually reduce its use as they grow.

Conclusion: Is White Noise Right for Your Baby?

Ultimately, the decision to use a white noise machine comes down to personal choice and professional advice. If your pediatrician gives you the green light, white noise could be a helpful tool to improve your baby’s sleep. Just remember, like any tool, it’s all about using it wisely to ensure your little one’s safety and comfort. With proper use, white noise machines can help soothe your baby, giving them (and you!) the restful sleep you need.
