Frequently Asked Questions

What is Nidra?

Nidra captures your brain activity during a 30-minute recording with the headband and creates a custom sleep sound built from your brain rhythm. You play this personalised sleep sound every night to help you unwind into deep, restful sleep.

How is Nidra different from white noise or sleep apps?

Standard sleep apps and white noise machines play the same sounds for everyone. Nidra is different because your sound is built from your own brain rhythm, your brain's own language, translated into sound. It feels familiar to you in a way a pre-recorded track cannot.

Can Nidra help me sleep better?

Nidra is a wellness tool for people who want to wind down and rest better. It is not a medical device and does not claim to treat sleep disorders. If your sleep troubles are severe or persistent, please consult a healthcare professional.

What can get in the way of restful sleep?

Stress, screens, irregular routines and a busy mind can all make it harder to wind down. Nidra helps by giving you a calming, personalised sound to ease into rest.

How long does it take to feel a difference?

Many Nidra users notice changes within the first week of consistent use. Because your sound is built from your own brain rhythm, it's immediately matched to you; there is no adjustment period.

Does my sound file ever need updating?

Your needs can shift over time, with stress, life changes, or as your sleep improves. Nidra allows you to re-record and refresh your personalised sound so it stays matched to who you are now.

Do I wear the headband every night?

No, and this is one of the things that makes the Nidra System different. You wear the Nidra Headband for just 30 minutes, while you're awake and winding down, to record your brain activity.

How does the Nidra Headband work?

You wear the Nidra Headband for 30 minutes while awake. It records your brain activity, the rhythm unique to you, and sends it to the app, which creates a personalised sleep sound matched to your brain.

How long does it take to get my personalised sound?

Once your 30-minute brain activity recording is complete, your personalised sleep sound is typically ready within 24 hours. You'll receive a notification in the Nidra app when it's ready to play.

What phones is the Nidra app compatible with?

The Nidra app is available on iOS (iPhone and iPad, iOS 14.0 or later) and Android (Android 8.0 or later). Bluetooth 5.0 is required to connect the headband.

Is my data private?

Completely. Your data is encrypted end-to-end and used solely to generate your personalised sleep sound. It is never shared with third parties, sold, or used for any purpose other than building your sound. Your data belongs to you.

What happens if the sound stops working as well?

Your needs can shift over time, with stress, life changes, or as your sleep improves. The Nidra app tracks your progress and prompts you when it's time to refresh your brain activity. A new 30-minute wind-down generates a refreshed sound, keeping your sleep solution as current as you are.

How is this different from a white noise app or sleep sounds playlist?

Generic sleep apps play the same sounds for everyone. Your Nidra sleep sound is built from your own brain rhythm, the specific sound matched to your brain, not a template. It feels familiar to you in a way a pre-recorded track chosen from a library cannot. That's the difference between broadcasting and personalisation.

Is the Nidra System a medical device?

No. The Nidra System is a lifestyle and wellness product. It is not a diagnostic tool and does not claim to treat, cure or prevent any medical condition. If you have health concerns about your sleep, please consult a qualified healthcare professional.

What's in the box?

The Nidra System includes the Nidra Headband, charging cable, quick start guide, and access to the Nidra app on iOS and Android.
