It requires a high level of health and well-being and an ability to command a person's inner resources. Some of the leaders who fall by the wayside simply don't have the stamina or resources to stay in the running. They can't cope with stress. Others keep running at high speed until they literally drop dead. To understand stress more fully, we must agree on a definition of what it is.
Stress is a biochemical response to performance.
When a person interprets a significant disruption as a threat, powerful hormones are released into the bloodstream, and the sympathetic division of the autonomic nervous system prepares the body for instant action-either to fight or to run for it. We usually tend to squelch our emotional and physical reactions, which can eventually damage our mental and physical well-being. Sources To be able to deal with stress, some common sources of stress need to be identified. The more predictable these disruptions are and the more control we believe we have over them, the less stressful they are for us. The long term effects of stress can result in ulcers, heart attacks, nervous breakdowns, and many others dangerous illnesses.
