Self-preservation is behaviour that ensures the survival of an organism. It is universal among living organisms. In some vertebrates, pain and fear are parts of this mechanism. Pain causes discomfort so that the organism is inclined to stop the pain. Fear causes the organism to seek safety and may cause a release of adrenaline, which has the effect of increased strength and heightened senses such as hearing, smell, and sight. Self-preservation may also be interpreted figuratively; in regard to the coping mechanisms one needs to prevent emotional trauma from distorting the mind.
