Solfeggio Frequencies for Sleep

Aug 24 2022 • 6 min read

If you’re looking for some healing sleep music to help you drift off, solfeggio frequencies are worth checking out.

Solfeggio frequencies relate to specific sounds that promote mind and body health. These frequencies incorporate tones that date back centuries and include sacred music and chants.

They were rediscovered in the 1970s by Dr. Joseph Puleo, a physician, and researcher. During his research, he discovered six measurable tones using mathematical numeral reduction. These tones were found to aid healing and balance out the body.

Thanks to Puleo’s work bringing the solfeggio frequencies back into public awareness, many scientists after him have discovered more evidence about the positive effects these frequencies can have.

They are even thought to stimulate the conscious and subconscious mind, helping to promote vitality and heal the mind, body, and spirit.

Solfeggio Frequencies: What the Science Says

The biochemist Dr. Glen Rein studied music’s effects on the human body in 1988. He wanted to learn how music affected DNA.

He studied four types of music with varying frequencies - Sanskrit chants, Gregorian chants, rock, and classical. By studying the rate of UV light absorption, which is critical to healthy DNA, he could assess how each type of music affected the body.

The Sanskrit and Gregorian chants increased UV light absorption by 5 - 9 % and were shown to have the most healing, positive effect. Classical music only increased UV absorption by tiny amounts, and rock music harmed the DNA by decreasing UV light absorption.

This research shows that sound frequencies can positively and negatively affect health and wellbeing. And this has led the way to sound therapy being used to manage a range of concerns such as reducing stress, lowering cholesterol, managing pain, lowering blood pressure, and improving sleep health.

Are There Any Negative Effects When Using Solfeggio Frequencies?

There have been no reported adverse side effects from listening to solfeggio frequencies. Even if you don’t like a particular frequency, it will not harm you.

If you are worried, consider working with a sound healing practitioner who can choose the correct frequencies for your goals and talk you through each session. A practitioner will use a mix of vocals and instruments such as tuning forks and gongs.


Each solfeggio frequency has a unique and uplifting effect that anyone will benefit from. This type of music can help rid you of low vibrations and negative energy and help remove emotional blockages that may be holding you back.

Incorporate solfeggio frequencies into your daily activities such as walking, reading, cleaning, meditation, or reading a book. And, when you want to drift off into a peaceful sleep, the 432 Hz and 528 Hz can be played as part of a healthy bedtime routine.
