The Purring Song of Cats | The Happy Sound That Lifts Your Spirits

The purring sound of cats helps regulate breathing and improve sleep quality. A study published in the journal "Animal Behaviour" in 2019 by the University of Cornwall in the UK found that people who hear cat purring have more regular breathing and more stable heart rates. The researchers recruited 20 healthy adults to participate in the study, asking them to listen to recordings of cat purring or white noise for 30 minutes before bedtime.
The results showed that participants who listened to cat purring not only had more regular breathing and more stable heart rates, but also experienced better sleep quality. Researcher Filipa Denis believes that the low-frequency vibrations of cat purring can stimulate the parasympathetic nervous system, thereby relaxing the body and improving sleep.
