There is evidence that white noise during development can be detrimental to the auditory system, disrupting the formation of tonotopic maps essential for processing sound frequencies, although it doesn't necessarily disrupt speech patterns permanently.

White noise can enhance learning in adults by modulating brain activity, but it may negatively affect auditory development in infants.

Once the auditory system has established tonotopic maps, background white noise at a low volume shouldn't pose a problem for learning, as it can support a heightened state of alertness and dopamine activation.

Studies show that low-intensity white noise can significantly improve performance in auditory working memory tasks by enhancing neural circuitry activation.

While binaural beats can help some people learn better, low-level white noise may be more effective for enhancing learning by modulating brain chemistry.

Utilizing low-level white noise and binaural beats can enhance brain states conducive to learning and dopamine release, facilitating better information retention.

In the evening, avoid bright artificial lights of any color, especially between 10:00 p.m. and 4:00 a.m., to optimize your sleep quality.

The idea that children should cry it out is misguided; in nature, a crying child is vulnerable and could be harmed, so it's important to respond to their needs.

Creating a dark environment at night is crucial; consider using blackout curtains and reducing light exposure an hour before bed.
