10 Causes of Fatigue
Reviewed: Dr. Mera
Cause #3: Stress
Stress refers to the response of the body to different conditions or situations such as a physical or psychological barrier. There are two main systems when the body responds to stress: hypothalamic pituitary adrenal axis and autonomic nervous system.
The activation of the fight or flight response through the sympathetic nervous system channels energy to body systems that are more relevant when adapting to stress, while the parasympathetic nervous system is there to help return the body to normal conditions. Through the different mechanisms, stress alters the body’s immune function, memory functions, metabolism, and susceptibility to disease. Too much stress can result in fatigue.
