White noise is the sound of all the frequencies that humans can hear and is at the same intensity, such as a fan or crashing waves.
Around the globe, millions of people are downloading white noise apps in the hope of getting better sleep at night. However, research suggests that they don't work and that they even may make things worse.
One theory is that white noise helps to drown out other bothersome sounds. Another is that listening to the same sound each night may help people to associate it with falling asleep.
Studies show that although there is evidence that people fall asleep sooner, the quality of the evidence was poor. There is also a concern of potential ill-effects of not allowing the auditory system to switch off overnight, although this has not yet been tested.

Researchers found that eating a diet high in sugar, saturated fat, and processed carbohydrates can negatively affect your sleep.
Foods rich in unsaturated fat, such as nuts...
Researchers found that eating more saturated fat and less fibre from foods like vegetables, fruits, and whole grains led to reductions in slow-wave sleep - the deep restorative kind of sleep.
People who consume a high-carbohydrate diet fall asleep much faster at night, but the quality of carbs matters. People who eat simple carbs and sugar tend to wake up more frequently throughout the night while eating complex carbs that contain fibre may help you obtain more deep, restorative sleep. This is because complex carbohydrates provide a more stable blood sugar level.
As people lose sleep, they may seek out more junk food. Healthy adults who sleep only four or five hours a night end up eating more calories and snacking on sweet foods more frequently.
