You can choose from different treatments from 20 to 55 minutes. It is also possible to combine treatments. At the Hydro Massage You lie on a waterbed that simultaneously massages your body. Next to you hangs a tablet with which you can adjust the intensity of the massage, music and scent. Above you hang red light therapy lamps that boost collagen production (provides a rejuvenating effect). Sounds good, right? When you choose the brain massage, you can choose between a 30 or 55 minute treatment. You lie in a separate cabin on a zero-gravity chair, which brings your brain into a deep, relaxed state—comparable to the restorative effect of deep sleep (theta state). This is due to the combination of vibrations and 4D sounds in the cabin. During this treatment, you catch up on sleep. If you choose the short treatment (30 minutes), it feels like you've had two hours of sleep. Yes, really—it's possible!
