Stress is a complex concept that has both mental and physiological components. Though most forms of stress are psychological, they trigger a variety of physiological changes. These changes include ones in the immune function, indicating a link between the stress and immune system.
Causes of Stress
A lot of things can cause stress. You may feel stress when you go on a job interview, take a test, or run a race. These kinds of short-term stress are normal. Long-term (chronic) stress is caused by stressful situations or events that last over a long period of time, like problems at work or conflicts in your family. Over time, chronic stress can lead to severe health problems.
