In the brain, serotonin is a neurotransmitter and regulates arousal, behavior, sleep, and mood, among other things. [9] During prolonged exercise where central nervous system fatigue is present, serotonin levels in the brain are higher than normal physiological conditions; these higher levels can increase perceptions of effort and peripheral muscle fatigue. [9]
These can include a decline in physical health, such as headaches, chest pain, fatigue, sleep problems, [1] and depression. The process of stress management is a key factor that can lead to a happy and successful life in modern society.

Signs of Directed Attention Fatigue include temporarily feeling unusually distractible, impatient, forgetful, or cranky when there is no ...
However, if the brain interprets an external stress demand as more urgent, it may supersede the immune and inflammatory responses and stimulate release of immune-suppressing stress hormones such as ACTH and cortisol. Once the stressor is resolved, the body resumes to amounting an adequate immune and inflammatory response, which may explain why ...
Long-term/chronic psychosocial stress is known to cause depression symptoms but the effect of chronic stress on sleep can lead to a ripple effect of further damage including poor emotional stability, lowered attention span and self-control, and worse performance on cognitive tasks. [4]
A primary target of stress is the brain. When exposed to stress, it serves as the centre to interpret the stressors and determine the appropriate behavioural and psychological responses. [7] Therefore, exposure to chronic stress will have a direct impact on brain function. [7] For instance, chronic stress inhibits neuron growth inside the ...
Stress is the leading cause of mental and physical problems, [citation needed] therefore feeling relaxed is often beneficial for a person's health. When a person is highly stressed, the sympathetic nervous system is activated because one is in a fight-or-flight response mode; over time, this could have negative effects on a human body.
