Psychology of Survival
2-5. Any event can lead to stress and, as everyone has experienced, events
don't always come one at a time. Often, stressful events occur simultaneously.
These events are not stress, but they produce it and are called
"stressors." Stressors are the obvious cause while stress is the
response. Once the body recognizes the presence of a stressor, it then begins to
act to protect itself.
2-6. In response to a stressor, the body prepares either to "fight or
flee." This preparation involves an internal SOS sent throughout the body.
As the body responds to this SOS, the following actions take place:
The body releases stored fuels (sugar and fats) to provide quick energy.
Breathing rate increases to supply more oxygen to the blood.
Muscle tension increases to prepare for action.
Blood clotting mechanisms are activated to reduce bleeding from cuts.
Senses become more acute (hearing becomes more sensitive, pupils dilate,
smell becomes sharper) so that you are more aware of your surroundings.
Heart rate and blood pressure rise to provide more blood to the muscles.
This protective posture lets you cope with potential dangers. However, you
cannot maintain this level of alertness indefinitely.
2-7. Stressors are not courteous; one stressor does not leave because another
one arrives. Stressors add up. The cumulative effect of minor stressors can be a
major distress if they all happen too close together. As the body's resistance
to stress wears down and the sources of stress continue (or increase),
eventually a state of exhaustion arrives. At this point, the ability to resist
stress or use it in a positive way gives out and signs of distress appear.
Anticipating stressors and developing strategies to cope with them are two
ingredients in the effective management of stress. Therefore, it is essential
that you be aware of the types of stressors that you will encounter. The
following paragraphs explain a few of these.
Injury, Illness, or Death
2-8. Injury, illness, and death are real possibilities that you have to face.
Perhaps nothing is more stressful than being alone in an unfamiliar environment
where you could die from hostile action, an accident, or from eating something
lethal. Illness and injury can also add to stress by limiting your ability to
maneuver, get food and drink, find shelter, and defend yourself. Even if illness
and injury don't lead to death, they add to stress through the pain and
discomfort they generate. It is only by controlling the stress associated with
the vulnerability to injury, illness, and death that you can have the courage to
take the risks associated with survival tasks.
Uncertainty and Lack of Control
2-9. Some people have trouble operating in settings where everything is not
clear-cut. The only guarantee in a survival situation is that nothing is
guaranteed. It can be extremely stressful operating on limited information in a
setting where you have limited control of your surroundings. This uncertainty
and lack of control also add to the stress of being ill, injured, or killed.
2-10. Even under the most ideal circumstances, nature is quite formidable. In
survival, you will have to contend with the stressors of weather, terrain, and
the variety of creatures inhabiting an area. Heat, cold, rain, winds, mountains,
swamps, deserts, insects, dangerous reptiles, and other animals are just a few
of the challenges that you will encounter while working to survive. Depending on
how you handle the stress of your environment, your surroundings can be either a
source of food and protection or can be a cause of extreme discomfort leading to
injury, illness, or death.
Hunger and Thirst
2-11. Without food and water you will weaken and eventually die. Thus,
getting and preserving food and water takes on increasing importance as the
length of time in a survival setting increases. Foraging can also be a big
source of stress since you are used to having your provisions issued.
2-12. Forcing yourself to continue surviving is not easy as you grow more
tired. It is possible to become so fatigued that the act of just staying awake
is stressful in itself.
2-13. There are some advantages to facing adversity with others. As a soldier
you learn individual skills, but you train to function as part of a team.
Although we complain about higher headquarters, we become used to the
information and guidance it provides, especially during times of confusion.
Being in contact with others also provides a greater sense of security and a
feeling someone is available to help if problems occur. A significant stressor
in survival situations is that often you have to rely solely on your own
2-14. The survival stressors mentioned in this section are by no means the
only ones you may face. Remember, what is stressful to one person may not be
stressful to another. Your experiences, training, personal outlook on life,
physical and mental conditioning, and level of self-confidence contribute to
what you will find stressful in a survival environment. The object is not to
avoid stress, but rather to manage the stressors of survival and make them work
2-15. We now have a general knowledge of stress and the stressors common to
survival. The next step is to examine your reactions to the stressors you may
