Which of the following is a trigger of the SNS?

The startle response is a rapid, automatic reaction to a sudden stimulus. It directly triggers the sympathetic nervous system, kicking in instantly to prepare the body for action: adrenaline release, increased heart rate and breathing, heightened alertness, and muscle readiness. This reflexive pathway doesn’t depend on conscious fear or risk assessment, which is why it’s the clearest trigger of the SNS in this context. Objective threat perceptions or objective fear can also provoke SNS activation, but they rely on cognitive appraisal and may not produce the immediate, reflexive surge that a startle does. Physical exhaustion tends to dampen arousal and is not a direct trigger for the SNS.
