This is known as the fight-or-flight response. It includes the release of adrenaline and noradrenaline. The heart rate increases, the pupils dilate, breathing rate increases to prepare the body to be able to survive the immediate stressful situation.

The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
The hypothalamus and the sympathetic nervous system are primarily associated with the general adaptation syndrome. The hypothalamus initiates the stress response, while the sympathetic nervous system activates fight-or-flight reactions in response to stress.

The autonomic nervous system, particularly the sympathetic and parasympathetic branches, regulates physiological changes that accompany an emotional response. The sympathetic nervous system is responsible for the "fight or flight" response by increasing heart rate, dilating pupils, and releasing adrenaline, while the parasympathetic nervous system helps return the body to a state of rest and relaxation after the emotional response subsides.
The sympathetic nervous system can influence tinnitus by modulating the stress response and altering auditory processing. Increased sympathetic activity, often associated with stress and anxiety, may heighten the perception of tinnitus or exacerbate its intensity. This heightened state can lead to increased arousal and attention to the tinnitus sound, potentially making it more noticeable. Additionally, chronic activation of the sympathetic nervous system may contribute to changes in neural pathways involved in auditory perception.
The sympathetic nervous system still allows us to have a fight or flight response, but it can also lead to an excessive stress response.
Sympathetic inhibition refers to a decrease in the activity of the sympathetic nervous system, which is responsible for the fight-or-flight response. This can result in a decrease in heart rate, blood pressure, and overall stress levels in the body. Sympathetic inhibition is often associated with relaxation, rest, and recovery.
The sympathetic nervous system is responsible for the body's "fight or flight" response to stress and danger. It activates various physiological changes, such as increasing heart rate, dilating pupils, and releasing adrenaline, to prepare the body to react quickly in threatening situations.
