It is caused by the neurohormone called norepinephrine.
The sympathetic nervous system is activated during stress, leading to the release of adrenaline and other stress hormones. This causes an increase in heart rate, blood pressure, and breathing rate, preparing the body for a "fight or flight" response. This heightened state of arousal helps the body to respond quickly to the stressor.
During the fight or flight response, the sympathetic nervous system activates to increase breathing rate and expand the airways in the lungs. This allows more oxygen to be taken in and circulated throughout the body to prepare for the physical demands of the stressful situation.
During rebreathing, the breathing pattern may change by becoming more shallow and rapid as carbon dioxide levels in the body increase. This can trigger a response to increase breathing rate and depth to eliminate excess carbon dioxide and restore proper oxygen levels in the blood. Rebreathing can cause effects like dizziness, tingling sensations, and light-headedness due to the altered gas exchange in the body.

During a fight or flight response, the release of stress hormones like adrenaline (epinephrine) triggers an increase in heart rate. This physiological response is designed to prepare the body for immediate action by supplying more oxygen and nutrients to the muscles and brain.
The two activities that are not increased during symphathetic response are abstract and methods. These are the too main ones.

During periods of high emotion, the sympathetic nervous system is activated, leading to the release of stress hormones such as adrenaline. This triggers an increase in heart rate and respiration to prepare the body for "fight or flight" response. This physiological response is meant to provide the body with the energy needed to cope with the stressful situation.
During exercise, the breathing rate can increase to around 40-60 breaths per minute or even higher depending on the intensity of the exercise and individual fitness level. This increase in breathing rate helps to supply more oxygen to the muscles and remove carbon dioxide from the body.
Emotion can affect the respiratory rate by triggering the body's fight-or-flight response, leading to an increase in breathing rate during states of stress, anxiety, or excitement. Conversely, feelings of calmness or relaxation can result in a slower breathing rate. Emotional factors can influence the autonomic nervous system, which controls respiration.
