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. ** Key Features & Functionality ** • Safe, 100% natural Long-Haul breathing therapy, requiring just minutes a day. • Harness 8 potent techniques for rapid Long-Haul symptom relief and ongoing improvement. • Benefits often noticeable within 24 hours. • Weekly assessments and graphs to measure and track your progress. • Progressive 16-stage guided program with three intensity levels. • Auto-adjusts exercise intensity based on your progress. • Co-created by a Long-Hauler along with leading post-viral research and trials. • Multiple breath counters and countdown timers within a user-friendly interface. • Access to additional Long-Haul resources, guides and tips to ensure you're on the right track. • Daily exercises tailored for morning focus, afternoon energy, and evening relaxation.

Many world-renowned Doctors and specialists recommend the program to their patients: Dr. Neil Nathan MD - Global Renowned Expert in Mold Illness, Founding Diplomate of the American Board of Integrative and Holistic Medicine "The majority of patients that I treat with chronic infections, such as Lyme disease, and chronic environmental toxicity, like mold, develop severe limbic dysfunction. I have found Ashok Gupta's program to be of great benefit in helping these patients to heal. In fact, when patients have become unusually sensitive or reactive, it is mandatory that they start with limbic retraining or they are not likely to make much progress. Hundreds of my patients have reported marked benefits from Ashok’s materials and I strongly encourage their use." Evan Brand, CFMP, FNTP - Functional Medicine Expert, Podcast Host and Author "As a Functional Medicine Practitioner, I've suffered my own series of health challenges. The Gupta Program has been the neuroplasticity piece that was missing from my personal and clinical protocols. I'm recommending literally almost every client we have to take the Gupta Program, especially since I've already seen progress in myself using the course. Change is possible!" Beth O'Hara, Doctorate in Naturopathy - Specializing in Functional Naturopathy, Mast Cell Activation (MCAS) and Histamine Specialist "At Mast Cell 360, the Gupta Program is a part of our core program for those with complex, chronic Mast Cell Activation Syndrome, Histamine Intolerance, Mold Toxicity, and related conditions. It was such a game-changer for our clients, we made it one of the first steps for anyone starting the Mast Cell 360 program. Thank you for offering this amazing program for those who are suffering to help them get their health and lives back!! It is truly a service to the world." Dr. Michael Ruscio DNM, DC Functional Medicine Expert The Austin Center for Functional Medicine “The Gupta Program is one of a kind, helping patients improve their health in a variety of ways and addressing a multitude of ailments.” Dr. Lauryn Lax, OTR, NTP Doctor of Occupational Therapy, Nutritionist, & Functional Medicine. Author. “This program works! The limbic system-immune connection is an often overlooked link in the chronic illness puzzle and a huge game changer in helping patients bust through the ceilings they are hitting in their health. What I love most about the Gupta Program is its holistic nature. It acknowledges all areas of health (physical, mental, emotional, spiritual) so you leave no stones unturned in getting to the root causes of your greatest health challenges."
