Stress is the combination of psychological, physiological, and behavioral reactions. Most people have a response to events that challenge or threaten them. Stress good and bad. Good stress is called eustress.
According to Hans Selye, a series of physiological reactions to stress occurring in three phases. Those phases are alarm, resistance, and exhaustion. This is also known as the general adaptation syndrome. General adaptation syndrome describes the body's short-term and long-term reaction to stress. Stressors in humans include physical stressors, such as starvation being hit by a car, or suffering through severe weather. Additionally, humans can suffer emotional or mental stress, such as the loss of a loved one, the inability to solve a problem, or even having a difficult day at work. The first stage of the general adaptation stage, the alarm reaction, is the immediate reaction to a stressors. This stage of stress has the reaction for physical activity. However, this initial response can also decrease the effectiveness of the immune system, making persons more susceptible to illness during this phase.
During stage two the stage of adaptation. This phase is the stress what the body is exposed to, the different stressors. Changes at many levels take place in order to reduce the effect of the stressors.
The last Stage number three, the stress has been going on for awhile now. Generally, this means the immune system, and the body's ability to resist disease, may be almost totally eliminated. Those who experience long-term stress may have heart attacks or severe infections due to reduced immunity.
Although stress can lead to disease, a researcher named Huethner has suggested that long-term stress may cause humans to better adapt to their environment. He argues that severe, long-term stress can cause persons to reject long-held assumptions or behaviors, and that stress can actually help the brain make physical changes that reflect these mental or emotional changes. In short, stress might allow persons to change the way they think and act for the better.
Stress is the cause of general adaptation syndrome and it can manifest as fatigue, irritability, difficulty concentrating, and difficulty sleeping. Persons may also experience other symptoms that are signs of stress. Persons experiencing unusual symptoms, such as hair loss, without another medical explanation might consider stress as the cause.
Stress is often not helpful and can even be harmful when not managed effectively. Moreover, stress can increase the risk of developing health problems, such as cardiovascular disease and anxiety disorders. This bad kind of stress is called distress, the kind of stress that people usually are referring to when they use the word stress.
