What do stress responses often lead to in terms of body functionality?

The selected answer highlights that stress responses typically result in heightened reaction time. When individuals experience stress, the body activates the fight-or-flight response, which triggers the release of adrenaline and other stress hormones. This physiological reaction prepares the body to react quickly to perceived threats or challenges. As a result, various systems in the body, particularly the cardiovascular and nervous systems, are primed for rapid response, leading to a faster reaction time.

During stress, the body also prioritizes certain functions, like oxygen and nutrient delivery to muscles, enhancing readiness for quick movement. This improved efficiency can be particularly beneficial in situations requiring immediate action. While other biological functions may be compromised temporarily, the focus on quick response and agility is a key survival advantage provided by stress responses.

In contrast, the other options don’t accurately represent typical outcomes of stress responses, as they either suggest improvements that are usually not seen under stress or indicate negative impacts on cognitive function.
