Who would have thought that the noise of the hair dryer could hook you! Yes, and a lot. Many become addicts to the noise. Who knows what would think Alexandre Godefoy, the French hairdresser who invented the device in 1890. The hum is monotonous and has a reassuring effect. According to those “addicts”, it isolates the person from the surrounding noises. It has no ups and downs, so it relaxes them and makes it possible to sleep.
The British medical journal of pediatrics “Archives of Disease in Childhood” analyzed the effect of white noises, such as that of the hair dryer, on infants. Two groups of 20 babies each were formed: 80% of them fell asleep within five minutes of sounding.
Other people use their noise when they are nervous. In case of hyperactive people, the sound deeply relaxes them and helps them sleep like babies. They love their continuous and keen frequency. It seems that the frequency which the hair dryer emits exerts a barrier of thoughts.
