Conflict not only triggers physiological stress responses but also changes an individual's perception and mental framework when they are engaged in combat.

This part of the book explores the significant changes in mind and body that people experience when faced with the pressures associated with combat situations. The book highlights that our natural defensive reactions are designed to enhance our likelihood of survival in perilous circumstances, but it also notes that failing to fully understand and manage these reactions can have significant consequences.

The body's physiological responses to combat stress are intended to increase chances of survival.

In combat situations, it is the autonomic nervous systems that primarily regulate the body's instinctive physiological responses, with a significant emphasis on the function of the Sympathetic Nervous System. The objective is to persist, accomplished by employing strategies that divert blood flow from less essential processes, bolster vital bodily functions, and occasionally reduce the perception of pain. Following a threatening situation, the body might undergo a pronounced response from the parasympathetic nervous system due to the considerable changes in energy and hormone levels.

A frequent reaction to stress during combat is the involuntary loss of control over bladder and bowel functions.

Grossman explains that experiencing a loss of control over bladder or bowel functions during combat should not be seen as a sign of frailty. He reveals that experiencing this type of response is a natural human behavior when confronted with intense survival situations. In these circumstances, the body prioritizes survival, thus redirecting energy away from non-essential functions like regulating the urinary and digestive systems. Grossman bolsters his argument by citing research that shows a significant number of World War II veterans shared similar experiences. He emphasizes the importance of acknowledging this reality, removing the stigma associated with it, and understanding that it is a natural instinct for self-protection.

In combat, it is the body's defensive mechanisms that are initiated by the Sympathetic Nervous System.

The physiological reactions of the body prepare an individual to confront a challenge or to flee from it. Your system is flooded with adrenaline and other hormones that prepare you to confront or escape from a threat. Grossman explains that such circumstances trigger a cascade of bodily reactions, including an acceleration of both heartbeat and breathing, dilation of the pupils, and a redistribution of blood flow from the digestive system to the muscles. Grossman refers to this phenomenon as the complete deployment of every resource for the sake of survival. The improvements lead to faster responses, increased power, and a higher tolerance for pain, all contributing to heightened effectiveness in combat scenarios.

After experiencing combat, individuals typically encounter an intense and robust reaction from the parasympathetic nervous system.

Once the danger has subsided, Grossman explains that the body's recuperative nervous system kicks in to counterbalance the effects of the fight-or-flight reaction. Combatants frequently endure fatigue, exhibit signs of sickness, and at times find it challenging to stay vigilant as their heart rate and blood pressure plummet rapidly, leading to a decrease in their overall energy. He underscores that vulnerability to dangers often increases in the aftermath of a victory, a notion commonly linked to Napoleon. Grossman underscores the importance of managing the body's response to stress to safeguard against imminent dangers and to prevent the long-term health consequences that come with prolonged stress.

Perceptions that change during combat can serve as a survival mechanism.

Grossman elucidates that, based on the studies conducted by Dr. Alexis Artwohl, individuals may undergo various perceptual alterations when subjected to the extreme stress of combat scenarios. These changes in how the brain processes sensory information, while they might seem strange, are generally evolutionary adaptations that enhance a soldier's concentration on immediate threats, enabling them to endure and continue fighting even under extreme circumstances.

In the throes of combat, individuals might find their hearing capabilities reduced.

Grossman delves into a phenomenon frequently observed by those in combat, where the report of firearms is perceived to be less loud than anticipated. Perceptual changes appear to originate from a psychological focus on the most crucial sensory data necessary for survival, especially vision, along with a physical response that reduces the ability to hear during sudden, intense noises. The brain has the ability to tune out specific sounds, like the noise from one's firearm, while heightening sensitivity to other auditory stimuli. Understanding that these responses are common during battle helps soldiers avoid undue anxiety or hesitation, even if it initially seems as though their weapons may not be functioning properly.

Combat often amplifies auditory experiences.

Grossman examines the occurrence where, unlike the experience of auditory exclusion, noises can seem amplified during violent encounters. Visual cues become scarce in situations with insufficient lighting. People often encounter an increase in their auditory perception during combat, making ordinary noises seem excessively loud. Training for scenarios that may arise during combat with limited visibility emphasizes the critical role of relying on one's sense of hearing to stay safe.

During confrontations, people frequently encounter a heightened focus that sharpens their attention on the present threat.

During high-pressure moments, individuals may experience a reduction in their visual field, resulting in a heightened focus on the immediate danger, a...
