When the body experiences stress, cortisol and adrenaline are released. These chemicals are suppose to be triggered primarily during survival situations. Currently, many people have a hard time getting away from stress which causes these chemicals to be released too frequently which is toxic for the body. As cortisol and adrenaline levels increase frequently, health complications can occur which is why stress is the leading cause for many illnesses such as diabetes.
