How To Manage Stress
Medical Editor: Leslie J. Schoenfield, MD, PhD
Stress is simply a fact of nature -- forces from the outside world affecting the individual. Hence, all living creatures are in a constant interchange with their surroundings (the ecosystem), both physically and behaviorally. This interplay of forces, or energy, is of course present in the relationships between all matter in the universe, whether they are living (animate) or not living (inanimate). However, there are critical differences in how different living creatures relate to their environment. These differences have far reaching consequences for survival. Because of the overabundance of stress in our modern lives, we usually think of stress as a negative experience. But from a biological point of view, stress can be neutral, negative, or positive.
Stress has driven evolutionary change (the development and natural selection
of species over time). Thus, the species that adapted best to the causes of
stress (stressors) have survived and evolved into the plant and animal kingdoms
we now observe. Man, because of the evolution of the human brain, especially the
part called the neo-cortex, is the most adaptive creature on the planet. This
adaptability is largely due to the changes and stressors that we have faced and
mastered. Therefore, we, unlike other animals, can live in any climate or
ecosystem, at various altitudes, and avoid the danger of predators. Moreover,
most recently, we have learned to live in the air, under the sea, and even in
space, where no living creatures that we know of have ever survived.
