What effects do high levels of thyroxine have on stress and on the body?
What will be an ideal response?
High levels of thyroxine can produce feelings of nervousness or anxiety, insomnia, increased heart rate, increased respiration leading to a sensation of shortness of breath, excessive sweating, diarrhea (due to increased gastric secretions and motility), and feelings of tiredness. The hormone can also amplify the effects of epinephrine, causing persons to experience more intense stress reactions to acute stressors than their normal reactions. Given its longevity and staying power relative to the majority of other stress-related hormones, the effects of thyroxine may explain why some individuals under chronic stress have difficulty returning to baseline levels once they leave a stressful environment. For example, some people have difficulty relaxing even during a one or two week vacation.
