3 Hours Pure 4 Hz Theta Isochronic Tones for Deep Meditation and REM Sleep | Deep Rest & Meditation

3 hours of pure 4 Hz Theta isochronic tones for deep meditation and light REM sleep. No noise, no music, just a black screen (01:00 onwards). WHAT ARE ISOCHRONIC TONES? The term 'isochronic tones' refers to a particular type of audio whose volume is modulated at a regular frequency. The idea is that the brain synchronises its activity to the frequency of the modulation. In this video, 4 Hz is associated with deep states of meditation or light REM sleep. Not as wakeful as 7 Hz, but not so much in deep sleep as 2 Hz. HOW CAN THIS HELP ME? You can use this audio in any way you like, but we recommend using this for meditation sessions and light sleep. HOW DO I USE THIS? Headphones or speakers work well for this audio. We've made the audio with a comfortable listening volume of 15-25% system volume in mind, but as always this varies from device-to-device, including your specific model of headphones, the device you're using to watch this video, and the environment you're in. We recommend that you listen to this audio in a quiet environment, as that is generally conducive to relaxation and good sleep. We've made the majority of this video black for those who aren't on YouTube Premium to help them save battery. If you're on mobile and you have YouTube Premium, you can set the volume to your comfort and then just turn off your screen and continue to listen to the audio. If you're on mobile and you do NOT have YouTube Premium, we recommend setting the screen brightness as low as possible to save battery while listening to the audio.
