An experience of a lifetime!
This product has changed my life for the better! My job leaves me often stressed and overwhelmed, but since I’ve started using Oxa at work, specifically the 18 Coherent Breaths exercise, I’ve noticed the immense changes it has made to my mood and focus. It’s effortless, immersive, and audibly soothing. Additionally, the shirt seamlessly fits under my work clothes, which is an added bonus!

Tolle App mit vielfältigen Möglichkeiten
Tolle App mit vielfältigen Einsatzmöglichkeiten, z. B. zur Entspannung oder auch nutzbar für Atemtrainings. Habe den Bra auch schon beim Singen getragen, um ein Gefühl zu bekommen wie intensiv der Körper dabei arbeitet.Die App kann sicher dabei helfen noch sparsamer mit dem Atem auszukommen um sich auch beim Singen weiterzuentwickeln.Das neue Schlaffeature ist spannend, bin schon gut in den Schlaf gekommen mit den Übungen. Weiter so, bin gespannt was die App noch an Überraschungen bereit hält.

Game-changer for stress
My job gets pretty hectic, and so I don't have a lot of time. The personalized breathing exercises on the app have really helped me relax and find inner calm everyday, even in short spaces of time. The bra is really comfortable and I barely notice it when I'm wearing it, so it slots into my day seamlessly.I'm feeling a lot more able to handle my stressful day-to-day because of Oxa, and so I highly recommend it to anyone looking for a holistic approach to stress management.

How to wear, use, and maintain Oxa. How is it different, and how it works.

How Oxa helps in reducing stress and improving sleep?

Oxa uses instant audio-visual biofeedback to guide the user through scientifically backed breathing exercises - effective within as little as 2 minutes.
These exercises are often based on resonance breathing (your optimal breathing frequency) - which is now much easier to learn thanks to Oxa's immediate feedback and guidance.

What is resonance breathing?

Resonance breathing is a powerful technique that syncs your heart rate and breathing- hence resonating.

This resonance differs for each person and occurs at breathing paces of 4 to 7 breaths per minute - much slower than the typical 12 to 20 breaths per minute during the day.
When in resonance, your parasympathetic nervous system is activated with each exhale - with an immediate relaxing and comforting effect.

What is the advantage of Oxa versus a smartwatch or meditation app?

The secret lies in the instant biofeedback.
Breathing is like music, where you learn your body's 'notes' and adjust them in real time. Unlike other wearables, Oxa can measure your live (> 200ms delay) breathing and heart activity. With this instant biofeedback, you can learn to use your breathing to get into "resonance" and relax. Oxa leads the breathing revolution at the intersection of Western and Eastern techniques. Interactive and immersive, Oxa is science and data-driven, different from meditation apps.

What is instant biofeedback?

Instant biofeedback assesses your body and mind with less than 200 ms delay - instant in human perception.

This allows you to intuitively learn how your body reacts to both external inputs and internal efforts.

Oxa uses this feedback to teach you various breathing techniques to improve stress management, sleep, and energy, the top one being resonance breathing. As a result, you will achieve an optimal personal relaxation frequency.

Is it comfortable to wear Oxa?

Oxa is comfortable by design and is meant to be worn day and night. The micromodal fabric is natural, light, and stretchable. Think 'high-tech pajamas.'

But don't take our word for it. Here's what our users say about Oxa on TrustPilot:

The app was easy to navigate, making it a pleasant experience. The sports bra was very comfortable, making it easy to wear for long periods of time. - Rocia Valera

The fabric of the bra is soft and comfortable. - Talita

Concerning the band itself, it's very comfortable, and I don't have any issue wearing it on a daily basis. - Hugo YecheGreat tool! Super comfortable and easy to use. Breathe & relax…feeling so much better! -

Is the Oxa app free?

Yes, the Oxa Life app is entirely free. There are no subscription fees or paid content.

Can Oxa be washed?

Yes. After disconnecting the sensor, Oxa garments can be machine-washed at least 100 times at 30°C.
In addition, Oxa comes with a unique washing bag assuring it will stay comfy and neat for a long-time. However, Oxa cannot be tumble dried.

Can I use Oxa during sports?

Oxa was designed for a relaxed, comfortable environment.
While Oxa can also be worn during physical activity (like in the gym or while running), the data will capture your movement and heart and respiratory rate changes.
If you want to exercise with Oxa, we recommend a tight body fit, where the Oxa band is the best choice of garment.
