In general, we can control voluntary bodily functions like waving our hands, chewing food, standing up, sitting down, and more. However, we usually cannot control involuntary functions like our heart rate, temperature, or blood pressure because these are controlled by our nervous system. This is where the Bio Feedback technique can be used. By learning the technique, we can control bodily functions better. It involves the use of wearable electrical sensors that monitor heart rate, skin changes, temperature, and even brain activity. Because we have visual data of our bodily functions, we can decide how to respond to negative sensations like stress, anxiety, pain, etc. There are many techniques that can be learned, such as deep breathing and muscle relaxation.
