Babies sleeping to the sound of a hairdryer is generally not very harmful.
Babies listen to the sound of the hair dryer to sleep is generally a habit, but the hair dryer is too loud, too close to the baby’s ears, blowing into the baby’s ears, may affect the baby’s sleep quality.
If the baby cries when listening to the sound of the hair dryer, it may be that the sound is too loud and the baby is afraid of the sound, so do not give the baby to listen to the sound of the hair dryer, so as not to scare the baby and have adverse effects.
It is suggested that other ways can be taken to let the baby fall asleep is safer, such as listening to soft music for the baby, children’s songs, etc., which is safer, but also allows the baby to have better sleeping habits.
