- Stress is a natural part of modern life. Caused by traffic, work deadlines, stress at home etc.
- It has been found that exposure to stress early in life may cause vulnerability to stress and anxiety.
- There is a molecular, cellular and structural differences in the brain of someone, with an anxiety disorder.

- Disorders are caused when the brain does not produce enough brainwaves, as they get out of balance due to stress, information overload, or illness etc.
- 1. Voluntary nervous system:
- Sends a message to the muscles for us to respond to sensory stimulation.
- Example – If you see a shark in the water, your first reaction would be to run away as fast as possible.
2. Autonomic nervous system:
- Made up of the sympathetic and parasympathetic nerve branches
- Sympathetic branch – causes arteries that send blood to the muscles to relax in order to increase the blood flow, for allowing a better reaction.
- The stress hormone adrenaline is released into the bloodstream, this helps to put the body into an arousal state to help cope with the challenge.
- Parasympathetic branch – helps regulate bodily functions and relax the body once the stress has passed.
- When these functions are left unchecked, disease could develop.
3. Neuroendocrine system:
- Maintains the body’s internal functioning
- Adrenaline travels through the blood and stimulates the release of the other hormones that affect the metabolic rate and sexual function.
- Signals are sent to the hypothalamus in the brain, where the adrenal gland excrete glucocorticoids, these are hormones that produce the many affects in response to stress.
- This includes storing energy in the blood
- Increasing heart rate
- Delaying the processes in the body that are essential during a crisis – eating, digestion, growth and reproduction.
- Glucocorticoid cortisol, promotes energy replenishment and efficient cardiovascular function.
- Cortisol levels peak in the morning hours just before you wake, and helps to turn on appetite and physical activity.
- Acute stress enhances the memory of past threatening events that increase activity of the immune system, which protect the body from pathogens.
- Glucocorticoids help the body respond to stress.
- Also helps the body with environmental change.
- Thus glucocorticoids are essential for survival.
