That’s a good question and I’m glad you asked that. Electromagnetic fields are present everywhere around you already. The Hapbee uses very low-frequency waves, much less than a cell phone. Hapbee works because we have mapped out how your brain responds to specific chemicals and replicated those with Hapbee signals. We aren’t introducing anything your body isn’t already used to. We are enabling you to choose when you want to feel your desired mood by giving you control over these sensations. More signals are in development.
