about this product.

PRE-ORDER for estimated January 2027 Shipping

The Bia Smart Sleep Mask is a neurofeedback sleep device that monitors brain activity in real time using fNIRS sensors embedded in the mask. It tracks sleep stages throughout the night and uses that data to coach you through them, with the aim of helping you fall asleep faster and spend more time in deep, restorative sleep. In the morning, you upload the night's data to the Bia Sleep App and review detailed sleep stage insights alongside personalised guidance.

Beyond tracking, Bia actively intervenes. Neural Soundscapes — piano, ocean, and noise options — play through built-in speakers and respond to your brain state. A smart sunrise alarm wakes you at an appropriate point in your sleep cycle. For travellers, the Time Shift programme is designed to address jet lag. Guided meditation is also built in. Bluetooth streaming with Auto-Pause means you can fall asleep to your own audio without any manual fuss.

The hardware is engineered with practical wear in mind. The 3D design is fully light-blocking with deep eye pockets, there are no hard components over the ears for side sleepers, and the fabric layers are machine washable via a medical-grade velcro attachment system. The electronics detach cleanly for cleaning.

This is a product for someone serious about sleep quality — whether that is an athlete monitoring recovery, a frequent traveller managing time zones, or anyone who has found standard sleep trackers too passive to be useful. The lifetime app subscription is included.

Bia Smart Sleep Mask with fNIRS brain monitoring sensors, built-in speakers with Neural Soundscapes (Piano, Ocean, Noise), USB-C charging cable, Bia Sleep App with lifetime subscription, customisable mask skin. Features include neurofeedback sleep coaching, guided meditation, smart sunrise alarm, Time Shift jet lag programme, Bluetooth streaming with Auto-Pause, and detailed sleep stage tracking. 100% light-blocking 3D design with deep eye pockets. Engineered for side sleepers with no hard parts over the ears. Machine-washable fabric layers with medical-grade velcro electronics attachment.

how to take it

i.

Charge the mask fully via the included USB-C cable, then download the Bia Sleep App and pair via Bluetooth. Select your programme — neurofeedback, guided meditation, or Time Shift — before bed, put the mask on, and it runs throughout the night without requiring an active Bluetooth or WiFi connection. In the morning, open the app to upload your sleep data and review your insights; to clean, detach the electronics via the velcro attachment and machine wash the fabric layers.

frequently asked.

How does fNIRS brain monitoring differ from typical actigraphy sleep trackers?

Most consumer sleep trackers — wristbands, rings, under-mattress pads — infer sleep stages from movement or heart rate, which is indirect. fNIRS (functional near-infrared spectroscopy) measures changes in blood oxygenation in brain tissue, giving a more direct read on neural activity and sleep stage transitions. It is the same measurement class used in some clinical research settings, applied here in a wearable form.

Does the mask need to stay connected to my phone all night?

No. Once you have selected your programme and put the mask on, it runs independently throughout the night without requiring Bluetooth or WiFi. You connect to the app in the morning to upload your sleep data and access your insights.

Is it genuinely comfortable for side sleepers?

The mask is specifically engineered with no hard components positioned over the ears, which is the main pressure point for side sleepers with most masks. The 3D design with deep eye pockets also means the mask surface does not press directly onto the eyelids. Fit is adjustable for comfort.

When will the Bia ship, and what does pre-order mean for my purchase?

All orders are currently pre-order only, with shipping expected July/August 2026. Check the product listing or contact us directly for the most up-to-date fulfilment information.

What is the Time Shift programme and who is it for?

Time Shift is a built-in jet lag programme designed to help you adjust to new time zones. It is most relevant for frequent travellers or anyone whose sleep schedule is regularly disrupted by crossing time zones. Select it as your programme before bed and the mask uses its coaching tools to support the adjustment.

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
