Nasal Breathing: ReViiV promotes nasal breathing 24/7 to increase the efficiency of your lungs, improve oxygen intake, reduce fatigue, and help restore taste & smell. 2. Prolonged Exhalation: By emphasizing long exhales, ReViiV aims to reduce breathlessness, relax your body, improve your sleep, and improve lung function. 3. Diaphragm Activation: ReViiV encourages deep 'belly breathing' to improve your lung function, reduce fatigue and shortness of breath. By stimulating the nervous system, it also reduces stress and anxiety, enhancing well-being. 4. Oxygen/CO2 Regulation: ReViiV aims to improve your lung capacity and balance the levels of oxygen and CO2 in your body by fostering the Bohr Effect, helping to alleviate symptoms like fatigue, breathlessness, and ‘brain fog’. 5. Regulated Immune System: ReViiV's breathing exercises are designed to keep your immune system in check, reducing inflammation and other immune-related symptoms often seen in Long-Haulers. 6. Olfactory Re-training: ReViiV incorporates specific exercises that can enhance your sensitivity to smell and taste, especially useful for Long-Haulers. 7. Breath-Holding: When you're ready, ReViiV introduces daily breath-holding exercises to help your body adapt to higher CO2 levels, improving overall body efficiency. 8.
