c) ‘To be effective, stress management techniques must target both the physical and the psychological aspects of stress.’
Consider the effectiveness of physical approaches to stress management.
Stress management is an attempt to cope with the stress response through reduction or elimination. It is based on changing the individuals perceived ability to cope with the stressful situation or reducing the physiological stress response (‘fight or flight’ response); this can be physiologically or psychologically based.
Physiological approaches include biofeedback and anti-anxiety drugs.
Biofeedback is technique in learning how to control involuntary muscles or voluntary muscles that cannot normally be controlled in order to reduce the effects of the stress response. It aims to reduce the ANS activity, which in turn reduces the stress sensations. It can consequently lower the effects of stress on health as the response is lessened. An individual is made aware of physiological activity, such as heart rate or blood pressure, which are involved in a stress response possibly via a machine. The individual is then trained in techniques to reduce these physiological aspects of stress. The control of these aspects is indirect and is usually affected by methods of relaxation. For example deep breathing can regulate an increased heart rate. The ANS responds to rewards and reinforcement and so is influenced by the individual seeing the positive effects of biofeedback.
Biofeedback can involve 3 stages;
- Developing an awareness of a specific physiological response.
- Learn ways of controlling that response in quiet conditions.
- Transferring that control into the conditions of everyday life.
Biofeedback has been found to produce short and long term reductions in physical stress responses and the return to a level of homeostasis following the disruption in the body’s natural functions caused by stress.
Biofeedback does not have to only be applied to stress. Dworkin and Dworkin (1988) worked with teenagers suffering from scoliosis. The teenagers successfully used biofeedback techniques to learn how to control the muscles of their spine, thus altering their posture and allowing them to overcome the disorder. This also demonstrates the relative successes of biofeedback.
Biofeedback produces a sense of control rather than just eliminating the physiological stress response. Unlike other physiological treatments for stress, such as drugs, this treatment is non-evasive and has no side effects allowing it to be used over the long term with much success.
The problems involved with biofeedback are that it is difficult to tell apart from relaxation methods, making it difficult to tell which is more successful. Biofeedback may be more successful in some candidates than in others as it requires commitment and a level of enthusiasm in the abilities of the treatment. Those who are sceptical have a negative attitude making them less willing to succeed.
Another way to reduce an individual’s level of stress is through the use of anti-anxiety drugs. These work on the chemical hormones produced by the body that create anxiety, they are countered by other drugs reducing anxiety. Barbiturates, benzodiazepines, beta-blockers and buspirone are the main categories of anti-anxiety drugs, otherwise known as sedatives, tranquillisers or anxiolytics.
Barbiturates are the least common type of anti-anxiety drug. They work on the central nervous system and are very effective in the reduction of anxiety though they have many side effects. Side effects include problems in coordination, concentration and slurred speech. Due to their addictive properties they have withdrawal affects such as delerium and increased sweating, as a result they have been basically replaced by propanediol and benzodiazepines.
Benzodiadepines are widely used today due to their effectiveness. They act on the neurotransmitters, especially GABA, which decreases serotonin activity reducing arousal. Librium and valium are examples of this drug. Although benzodiazepines are less dangerous than barbiturates with less chance of overdose they are addictive and produce a severe withdrawal syndrome, once removed the original anxiety problems return. Also they have unwanted side effects making people drowsy, causing cognitive and memory impairment, depression and mix poorly with alcohol.
Beta-blockers reduce the activity in the sympathetic nervous system in order to reduce anxiety. They act directly on the heart rate and blood pressure, lowering both. They do not affect brain activity. An advantage is that beta-blockers do not cause a dependency though a problem could be recognised in that it does not target the problem only the symptoms. As with all anti-anxiety drugs there are side effects such as cold extremities, fatigue, nightmares and hallucinations.
Buspirone is the most recent of the anti-anxiety drugs. It helps the effects of the neurotransmitter serotonin. It does not have sedative effects but does have side effects such as headaches and depression although there are no withdrawal symptoms.
Anti anxiety drugs can be very effective in reducing the intense feeling of anxiety associated with stress though a despite this they have many flaws. A major flaw in the use of drugs to combat anxiety is that fact that they do not attack the problem causing anxiety only the responses to the anxiety as a result the problem may reoccur causing a vicious cycle involving anxiety and drug dependency. It is advised that drugs should only be used for a short-term severe cases and so do not solve long-term problems though they can cause further long terms problems through their use due to dependency and side effects.
