What is a common physical symptom experienced after a traumatic incident?

Nausea and extreme weakness are common physical symptoms that can occur after a traumatic incident due to the body's acute stress response. In response to trauma, the body releases hormones such as adrenaline and cortisol, which can lead to a variety of physical sensations and reactions. Nausea can arise from the body’s fight-or-flight reaction, as the digestive system may slow down, which often results in feelings of queasiness. Extreme weakness may stem from the physical and emotional toll of the trauma, as the body may become fatigued after facing a highly stressful situation. This response highlights the impact of trauma not only on emotional and mental well-being but also on physical health.

The other options do not align with typical responses to traumatic experiences. Increased energy levels can occur, but this is usually short-lived and not sustained after severe trauma. Enhanced physical strength and improved cardiovascular function are not commonly reported symptoms but rather more specific reactions that may occur in selective circumstances or when one is actively responding to a threat, not generally after the trauma has occurred.
