About Oxa Reconnect with your body 2 In today’s world, many people are losing their connection to their bodies as they are constantly put under pressure and exposed to mental stress. Oxa allows you to reconnect with yourself using an ancient link between body and mind: your breathing. “Life with Oxa” is all about giving you the resources you need to give your life a breath of fresh air. [1] Oxa allows you to monitor and influence your nervous system with the aim of improving your well-being. Oxa leverages a proprietary biofeedback app powered by next-gen smart garments and precision technology to help you influence your autonomic nervous system. That is the part of your nervous system that controls involuntary bodily functions like breathing and your heart beating. [1] Oxa allows you to reconnect with yourself by strengthening the link between your body and mind through conscious breathing. As a result, Oxa can help relieve everyday stress, sharpen your focus and improve your sleep quality. What can you do with Oxa? With Oxa, you can monitor your physiological parameters and state in real time, observe their past and future trends, and understand the long-term impact of your everyday activities on your health. Oxa technology 3 [Animated renders of e-components + sensor to explain the technology] Smart garments Oxa’s technology consists of state-of-the-art e-textile components and sensors that are seamlessly integrated into a comfortable, modern shirt or bra you can wash. The connected garment communicates with an exclusive app that guides you while keeping your data anonymous and secure. It is a powerful tool putting you in the driver’s seat on your health journey. Oxa bras and shirts are made with a breathable, comfortable fabric with a lovely soft texture and plenty of stretch. Biosensors 4 Lung activity: Oxa uses proprietary technology to measure your breathing depth and rate in real time. Heart activity: our very own state-of-the-art dry adhesive electrodes detect complete heart activity via an electrocardiogram (ECG) from which the heart rate (HR) and heart rate variability (HRV) are extracted in real time. Resting HR and HRV are key indicators of the level of stress the nervous system is under. By monitoring lung and heart activity together, Oxa provides a powerful framework for measuring the activity of the parasympathetic nervous system, which relaxes your body after periods of stress. Skin temperature: a highly accurate built-in infrared sensor detects the skin surface temperature by measuring heat radiation. Accelerometer: the sensor is equipped with an accelerometer which provides information on your movements and position. [image: 001_warning-icon.png] [3]Important safety information Oxa is not a medical device. Please note that Oxa is not designed to diagnose, treat, cure or prevent diseases or medical conditions. The information and guidance in the Oxa journey are provided for informational purposes only and should not 5 be used as an alternative to advice given by physicians or other health professionals. You must always consult a physician if you have any questions regarding a medical condition or any changes you wish to make to your activity or sleep based on information or guidance from Oxa. If you do decide to make any changes to your sleep or activity based on information or guidance from Oxa, you do so entirely at your own risk. It is important to always remain sensitive to your body’s responses. For example, if you feel pain, fatigue or discomfort that is unexpected, repeated or long-term as a result of making changes to your sleep or activity, it is recommended that you speak to a physician before continuing. Information and guidance from Oxa may be interpreted differently if your physiological functions and responses are significantly different than the average physiological functions and responses due to medical conditions or rare natural differences. The Oxa system uses passive electrodes, which do not pose a health hazard. They are biocompatible and do not cause irritation. If you experience any redness or skin irritation due to the electrodes being in contact with your skin for an extended period, remove Oxa immediately. Skin rashes may be caused by friction between the garment and the skin. If any symptoms last for longer than two or three days after you stopped using your Oxa product, contact a physician. If you, or anyone who intends to wear Oxa, have an epileptic condition, consult a physician before you use Oxa. If you experience any of the following symptoms during use – dizziness, altered vision, eye or muscle twitches, loss of 6 awareness, disorientation, involuntary movement, or convulsions – discontinue use IMMEDIATELY and speak to a physician. Hyperventilation in power breathing is only suitable for people who are generally healthy. If you have any ongoing health conditions — or if you suffer from anxiety — please consult your doctor before practicing hyperventilation. If you are pregnant, don’t practice hyperventilation. Long breath holds could harm your baby. The Oxa sensor complies with Directive 2014/53/EU and meets the FCC Radio Frequency Radiation Exposure…
