By releasing such chemicals as cortisol, adrenaline and noradrenaline into the bloodstream, the instinctive feeling of whether to "fight" or take "flight" is experienced during instances of stress.

If the situation can be controlled, or walked away from, the raised levels will subside. However, if this is not possible, they continue to build up and become excessive. As a result, heart rate increases, sweating occurs and sugars are released. This serves to just heighten stress levels, and the vicious circle is completed.

Applying stress reduction techniques at the very first sign of such an event can head the feelings off. Being able to recognize the situations most likely to trigger this reaction is a first step. There are several stress reduction techniques available if self help techniques fail to work. However, before trying any of them, it is highly advisable to seek professional medical guidance.

Relaxation is the key to bringing stress under control. At the first sign of stress instinctively, muscles tense, which can cause further problems such as pain and headaches. The best method to help relax is to apply simple deep breathing methods. One proven method is to inhale deeply and smoothly until the count of four. Hold the breath in for another count of four. Then exhale for a further count of four. This process helps to take in fresh oxygen in the blood stream, canceling out the negative effects of the chemicals.

There are of course many products and companies offering to provide stress reduction techniques. A simple search online will return numerous results. But for a quick and simple technique, deep breathing, exercise and fresh air are quite effective for occasional stress.

A common reaction to stress, for a significant number of people, is to immediately get a cup of coffee and light up a cigarette. This couldn't be more wrong. Nicotine and caffeine will only help to heighten feelings of stress. Indeed, such is the virulence of their effects that reducing or quitting smoking and caffeinated products can help avoid stress. Prevention is better than cure, after all.
