The body's typical response to acute stress involves the activation of the fight-or-flight response. This physiological reaction is primarily mediated by the autonomic nervous system and the release of stress hormones, such as adrenaline and cortisol. When faced with a perceived threat or challenge, the body prepares itself to either confront the danger or flee from it.

This response triggers various changes, including increased heart rate, heightened alertness, and redirected blood flow to essential muscles, allowing for improved physical performance. Additionally, energy production is ramped up, and non-essential functions, such as digestion, are temporarily suppressed to prioritize immediate survival. The fight-or-flight response is a crucial survival mechanism, enabling individuals to react quickly in potentially life-threatening situations.

The other options do not accurately reflect the body’s immediate responses during acute stress. For instance, during acute stress, activation of the digestive system is reduced rather than enhanced, and there is typically an increase in fatigue levels due to the energy expended in dealing with the stressor. Sleep quality is often negatively impacted, as acute stress can lead to insomnia or disrupted sleep patterns. Hence, the correct answer highlights the body's instinctive and protective physiological adaptations to acute stress.
