This practice session focuses on understanding neurotransmitters and their impact on the body. Switching, which can affect testing accuracy, can be tested through muscle strength, hair pull test, and touching switching points. Different types of switching, such as left-right, up-down, and front-back switching, can lead to opposite responses and learning challenges. Factors causing switching include diet, stress, emotional factors, and exposure to EMFs. Balancing neurotransmitters can be achieved through various methods like holding the umbilicus and rubbing the corresponding switching point, lifestyle factors (diet, sleep, exercise, stress management), positive addiction, meditation, gratitude practices, and integrative medicine. It is important to discuss medications for neurotransmitter imbalances with a doctor, while natural methods can support balance. Additionally, preparing for dental procedures involves rubbing points and using deep breathing techniques, and alternative options like Cologuard exist for colonoscopies.
