The 432 Hz frequency is used in music for deep sleep and relaxation. This frequency is considered beneficial for raising positive vibrations and helping to achieve a state of calm and healing. Additionally, Solfeggio frequencies are also useful for balancing and healing. Listening to them at least three times a week for 15 minutes per session can be beneficial.
Remember that music while you sleep works best with Theta waves (3-8 Hz) and Delta waves (0.5-3 Hz). If you prefer not to use headphones, you can also listen to isochronic tones, which do not depend on two separate rhythms3.
