During the stress response, processes such as digestion and immune function typically do not occur effectively. The body prioritizes immediate survival by diverting energy away from these systems to focus on responding to the perceived threat. Additionally, prolonged stress can lead to negative impacts on mental health, but normal cognitive functions such as reasoning and decision-making may be impaired rather than completely absent.
The ALARM response
Peak concentrations of stress hormones in the bloodstream occur shortly after encountering a stressful situation. This physiological response is part of the body's fight-or-flight reaction to stress, designed to mobilize energy and resources for immediate action. The levels of stress hormones typically decline as the body's stress response subsides.

The hypothalamus is a key brain structure that initiates the physiological response to stress. It activates the body's stress response system, known as the hypothalamic-pituitary-adrenal (HPA) axis, leading to the release of stress hormones like cortisol. This triggers the body's fight-or-flight response to help cope with the perceived threat.
The term combat stress refers to the psychological and physiological reactions that occur during or after combat. It is a short term response and is not a psychiatric disorder.
Sympathetic Nervous System is the part of autonomic nervous system that prepares the body for action and stress.

The main gland involved in the stress response is the adrenal gland. When faced with stress, the hypothalamus signals the adrenal glands to release hormones such as cortisol and adrenaline. These hormones help the body respond to stress by increasing heart rate, blood pressure, and energy availability. This response is part of the body's fight-or-flight mechanism.
Deformation of matter refers to the change in shape or size of a material in response to an applied force or stress. This can occur in solids, liquids, or gases, where the material's particles rearrange or move in response to the external force. Deformation can be reversible or irreversible depending on the material and the amount of stress applied.
One skin condition that can arise from shock is acute stress dermatitis, which manifests as redness, itching, or a rash due to the body's response to stress. Additionally, conditions like hives (urticaria) may occur as a result of an acute stress response. These reactions are typically temporary and resolve as the body stabilizes after the shock.
Sympathetic nerves: prepare the body for emergencies and stress by increasing the breathing rate, heart rate, and blood flow to muscles. These nerves become aroused as part of the fight-or-flight response, which is the body's natural reaction to real or imaginary danger.
