Bía Sleep encourages your brain to transition and stay in a desired sleep state using Neurofeedback. This gentle guidance has a lasting effect as it trains your mind to enter each sleep state faster.
For neurofeedback to work, we use functional near-infrared spectroscopy (fNIRS) to measure brain activity. fNIRS allows us to get a deep understanding of sleep activity, even when you toss and turn, without making contact with the skin. It's the perfect choice for sleep.
Once measured, Bía Sleep plays back your brain activity using bone-conduction audio. This technique is known to help reduce stress by activating a calming sensation. Bía Sleep's Neural Soundscapes has been shown to double deep sleep.
Bía is intended for adults aged 19 and older. Bía Sleep is helpful for individuals who look to establish a healthy brain routine aimed at mastering sleep.
It is important to understand that Bía Sleep is not a medical device and is not intended for diagnosing or treating clinical or mental health conditions. We're focused on helping people sleep by creating cutting-edge technology products intended for general use. If you have, or think you have, a condition, you should speak to your doctor before you use Bía Sleep.
Bía Sleep was created by side-sleepers, for side sleepers.
Bía is made with soft materials that are breathable and light. Since it has no hard parts along the sides of the head, you won't feel any unwanted pressure - no matter the position you sleep in.
Bía Sleep is designed to fit all head shapes, big or small, perfectly. We include an adjustable strap with every purchase. If the adjustable strap is too big or too small, please message us for a replacement.
