Sympathetic nervous system (SNS)

When a person is in a stressful situation, the sympathetic nervous system (SNS) is activated. This system triggers a series of physiological responses that prepare the body for a fight-or-flight response. These responses include increased heart rate, increased sweating, and increased body temperature.

The SNS is a part of the autonomic nervous system, which controls involuntary bodily functions such as heart rate, digestion, and respiration. The SNS is activated when the body perceives a threat, and it works to prepare the body to respond to that threat.

In a stressful situation, the SNS releases hormones such as adrenaline and noradrenaline. These hormones cause the heart rate to increase, the blood vessels to constrict, and the sweat glands to activate. The increased heart rate and blood vessel constriction help to increase blood pressure and deliver more oxygen and nutrients to the muscles. The sweat glands help to cool the body down.

The SNS also plays a role in regulating body temperature. When the body is in a stressful situation, the SNS releases hormones that cause the body temperature to increase. This increase in body temperature helps to prepare the body for a fight-or-flight response.
