Stress is the combination of psychological, physiological and behavioral reactions. Most people respond to events that challenge or threaten them. Stress the good and the bad. Good stress is called eustress. According to Hans Selye, a series of physiological reactions to stress occurs in three phases. These phases are alarm, resistance and exhaustion. This is also known as general adaptation syndrome. General adaptation syndrome describes the body's response to short- and long-term stress. Stressors in humans include physical stressors, such as starvation, being hit by a car, or suffering from extreme weather conditions. Additionally, humans can suffer from emotional or mental stress, such as the loss of a loved one, the inability to solve a problem, or even a difficult day at work. The first stage of the general stage of adaptation, the alarm response, is the immediate reaction to a stressor. This stage of stress has the reaction of physical activity. However, this initial response can also decrease the effectiveness of the immune system, making people more vulnerable to illness during this phase. During the second stage, the adaptation stage. This phase corresponds to the stress to which the body is exposed, to the different stress factors. Changes take place at several levels to reduce the effect of stressors. The last step number three, the stress has been going on for a while now. In general, this means that the immune system and the body's ability to resist disease can be almost completely eliminated. Those who experience long-term stress may have heart attacks or serious infections due to reduced immunity. Although stress can lead to illness, a researcher named Huethner suggested that long-term stress can cause humans to feel bad. paper...those who are physically fit have fewer illnesses than those who are not and have the same stressors (421). Coping with stress doesn't mean you can prevent all forms of getting sick. It simply means how to deal with stress in your life and how to live with the inevitable problems that life throws at you.
