Not only relying on prescriptions or health supplements, scientists have discovered new benefits of sound for human health. Discover the wonders of sound in everyday life!

The magic of sound

Sounds have color                 

Although invisible, sound actually has distinct colors, such as white, pink, red, blue, purple, gray, black, brown. This name refers to the difference in energy levels after each octave of the emitted frequencies, which is the name for the noises that are widely used in life. Among them, white, pink and brown noises are noises that are beneficial to life.

White noise is a harmony of different sounds with frequencies of 20 – 20,000Hz emitted at the same time. It can be imagined as a musical synthesis of familiar sounds such as: the sound of rain, the sound of waterfalls, the hum of air conditioners, hair dryers, the static of radios… That is why this noise is often used to overwhelm other noises, helping the nerves to be less sensitive to outside sounds. In particular, this noise is really useful for people with insomnia at night. In addition, this sound is also used to help children cry less, reduce stress and sleep better. Also created from a similar frequency to white noise, pink noise is said to have a more balanced and natural sound. In a recent study, pink noise was found to be more effective than white noise in inducing sleep, promoting deep sleep and enhancing memory. Played at a lower frequency, brown noise is a “rougher” sound than pink noise, like the roar of a river or strong wind, helping listeners relax, focus and improve their mood. Different people respond to different types of noise. You can find these noises in natural noises, or artificial noises such as phone apps and recordings available on the internet.

The effects of music

We all know music as a tonic for the spirit, but music has much more potential than that. During World War II, some doctors used music to treat patients, to ease their pain and dispel the fear of war. This not only changed the patient’s condition, reducing the pain signals transmitted through the spine, but also helped improve the inflammation of the wound, leading to a decrease in mortality. In fact, using different types of music can help us improve our current life and health:

Reduce fatigue

Music can make physical activities more enjoyable, make exercise time pass faster than usual, reduce fatigue, increase nerve stimulation, create physiological relaxation responses and improve motor coordination. In addition, music reduces muscle tension and improves body movement and coordination. For patients with movement disorders, music plays a role in developing, maintaining and restoring physical function during rehabilitation.

Helps work efficiently

People’s ability to perceive images, including letters and numbers, is improved when listening to classical music. Music can also eliminate fatigue caused by physical activity or fatigue symptoms caused by monotonous work. However, choose soft ballads because listening to too much pop and hard rock can make you restless.

Improve health

After undergoing surgery, patients are often told to listen to music to bring about a comfortable state of mind, helping the wound heal faster. Music helps reduce pain in situations such as childbirth, speeds up metabolic recovery after stress, and recovers faster after strenuous exercise. This is because music helps increase metabolism and reduce lactic acid levels during and after exercise. Focusing on a favorite tune will also reduce pain by distracting the focus from the wound.
