When facing down any impending problems, like an oncoming car or deadlines, the body synthesises physical stress that prep us to either fight the situation or flee from it.
This fight-or-flight response is driven by the sympathetic nervous system, a perfectly balanced network of brain structure, nervous system and hormones that, if got hindered can create some critical complexities.
The sympathetic nervous system is partly related to the autonomic nervous system, which is also classified as the involuntary nervous system. Without having any conscious direction, the autonomic nervous system manages vital body functions like heart rate, blood pressure, pupil dilation, body temperature and digestion. Research also shows that different types of nerve cells, known as neurons, is responsible for regulating diverse physical reactions by controlling the actions of skeletal muscle, cardiac muscle and gland secretion. This system is solely responsible for quick internal adjustments in animals.
The sympathetic nervous system orders the body's active involuntary response in the danger and stressful situations. Rapid secretion of hormones increases the body’s vigilance and heart rate, leading to the flow of extra blood to the muscle. Breathing quickens, fresh oxygen is delivered to the brain, and glucose is infused in the bloodstream for a quick energy lift. The whole actions happen so fast that the person does not realise when it takes place. Take an example, that a person may jump from the path of a falling tree before they even realise the toppling.
The sympathetic nervous system does not distress the body function, once the situation is passed. Another important aspect of the autonomic nervous system is it works to calm the body down. This system encourages the body to rest and digest, have a normal breathing rate and a balanced hormone flow.
The whole work of sympathetic nervous systems is to maintain the baseline of normal body functions.
