Our application is developed in order to reproduce exercices that will help your body come back to slow breathing, thus increasing CO2 and its protectives effects. Increasing CO2 and stop hyperventilation will help with anxiety, depression and all type of degenerative issue. It will also increase the quality of sleep which will have a direct impact on your regeneration and stabilize nervous system. Hyperventilation Repetitive stress trigger our body to breathe faster due to the emergency response. This is called Hyperventilation. Hyperventilation trigger anxiety which trigger more hyperventilation and all type of degenerative diseases (anxiety, depression, asthma, hypertension, hypothyroidism, gastritis, diabetes and others). Famous Ukranian Doctor Buteyko said : « Hyperventilation is the cause of all diseases of today ». The Application According to numerous studies, healthy people have slow breathing (around 6 per minute). In the preview document for exemple we can read : Slow respiration at 6 breaths per min was found to be optimal for improving alveolar ventilation and reducing dead space in both groups in terms of increased arterial oxygen saturation and ease and sustainability in terms of respiratory effort. Many other studies exist about that, and also several traditional rituals such as old Chinese Taichi where the main goal was to control your breath in order to feel well. The application provides large scale of level depending on your initial situation. If you are high hyperventilating and really anxious begin with low level (12 breaths per minute) and train with that until you feel confident. Then switch to the next level (11 breaths per minute) and continue this process until you reach slow breathing levels (6/7/8 breaths per minute). If your initial level is higher feel free to adapt yourself and train until you can slow your breath again. Sleeping Mode Anxiety is often characterized by over-stimulation of nervous system which can trigger panic attack caused mainly by hyperventilation. Dr. Andrew Weil has developed on the same principle a very helpful breathing technique to fall asleep and reduce stress at night : The 4 7 8 ! The 4-7-8 breathing technique is a breathing pattern developed by Dr. Andrew Weil. It’s based on an ancient yogic technique called pranayama, which helps practitioners gain control over their breathing. The 4-7-8 technique forces the mind and body to focus on regulating the breath, rather than replaying your worries when you lie down at night. Proponents claim it can soothe a racing heart or calm frazzled nerves. Dr. Weil has even described it as a « natural tranquilizer for the nervous system« . The method is simple : Breathe in 4 seconds, Hold breathe 7 seconds, Exhale 8 seconds until you free your mind, relax and sleep.
