Fear and anxiety lead to stress. When you are stressed, adrenaline drips into the system. When you live like this long-term you do great physical harm to your body.
Forced to remain in situations that produce stress, your metabolism changes. The human body is simply not constructed to constantly operate on emergency power. Long term exposure to high levels of adrenaline leads to disorders such as hypertension. Over-exposure can lead to loss of appetite, insomnia, fatigue, loss of libido, irritable Bowel Syndrome and a general decline in health.
Adrenaline harms our immune systems, contributes to heart disease and helps in the development of cancers. A long-term study of 400 male and 200 female executives—people who routinely operate under high levels of adrenalins—showed that the men suffered more heart problems and the women more cancer than people who had less stressful, anxiety-causing jobs.
