** Steady Improvement over 16 Stages **

ReViiV is designed to quickly relieve many common Long-Haul (PASC) symptoms, including Fatigue, Taste/Smell loss, Breathlessness, “Brain Fog’, Muscle/Joint pain, Insomnia, and more. ReViiV uses 5-minute daily breathing exercises, progressively tailored to your needs, to both relieve symptoms and facilitate steady, incremental improvement over 16 stages. Weekly assessments and graphs show your progress along with visual aids, detailed guides, and resources to ensure proper technique.

** Featuring 8 Scientifically Backed Techniques **

Drawing from the latest Long-Haul (PASC) research, as well as respiratory and cognitive-behavioral therapy, ReViiV's effectiveness stems from 8 scientifically backed techniques fused into a highly effective breathing program:

1. 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. Stress Reduction and Mindfulness: ReViiV includes mindfulness techniques to help reduce fatigue, improve sleep, and combat stress, anxiety, and depression.

The Perfect Solution for My Long Covid

I’m glad to see this app available. I did this exact breathing exercise when I had long Covid and within a few days my sense of smell started to return. After about a week or two I was back to normal! Anyone who suffers from long Covid should get this app. Very easy to use as well.
