Free radicals are inflammation's primary cause.
Scientists and medical researchers cite free radicals as the primary cause of inflammation. This means that inflammation occurs in cells due to free oxygen radicals that occur when blood stagnates due to poor metabolism.
Free radicals are caused by blood circulation disorders, and blood circulation disorders are caused by stress hormones that stiffen all smooth muscles. Why are you stressed? Is it because your thoughts and environment do not match the information input to your brain? Naturally, the brain thinks more, and brain cells require more oxygen. The body takes deep breaths, but the chest narrows, and the brain cells do not receive enough oxygen to meet their needs.
If you take deep breaths without your chest and body relaxing, your chest will become stressed. The entire human body becomes rigid, strong stomach acid and stress hormones are secreted, and all smooth muscles, including blood vessels and bronchial tubes, shrink. What happens when smooth muscles shrink? Blood stagnates. What happens when blood stagnates? Active oxygen is produced. This vicious cycle causes inflammation in cells.
