Homeostasis is defined as the means by which the internal atmosphere of the human body remains balanced regardless of the numerous changes within the environment (Mastrangelo, 2013). One of the most remarkable attributes of homeostatic control is body temperature regulation. Thermoregulation is controlled by the autonomic nervous system (ANS), which is a vastly complex, multifaceted neural system that sustains the internal homeostasis of the human body (Chawla, 2013). Within the ANS, is the sympathic nervous system (SNS) and the parasympathetic nervous system (PSNS). Predominately, thermoregulation is controlled by the SNS with little contribution from the PSNS (Chawla, 2013). Although the human body experiences various temperature deviations,

A negative feedback loop is a system the body utilizes to reverse changes within an organized condition (Tortora, 2012). Within a negative feedback loop, an opposition to change takes place within the body. The change originates a response which brings the body back into an average range. Negative feedback groups include receptors, effector, and a control center (Mastrangelo, 2013). Negative feedback is the mechanism of action in maintaining a balanced core body temperature. The receptors are responsible for detecting a change in temperature within the body. A processing center is then in charge of receiving the information from the receptors and directing a response based on the information received. Finally, an effector produces the response sent from the control center and makes sure the body’s core temperature remains constant (Tortora, …show more content…
During exercise the mechanisms of homeostasis act in order to prevent the core body temperature from increasing excessively. However, many athletes practice in hot and humid weather conditions which intensify the test that physical exercise places on the thermoregulatory processes. The hot and humid setting weakens the heat exchanges between the body and the environment considerably. The struggle between the body and environment can lead to serious heat illnesses in athletes, such as, heat stroke, dehydration and heat exhaustion (Wendt, 2007). When an individual exercises, their core body temperature increases from their inactive state. As the body temperature steadily increases, heat loss responses are signaled in order to reach a new stable body temperature. However, a new stable body temperature is not always attained, this results in inevitable hyperthermia. Hyperthermia is when thermoregulation fails. In other words, the human body generates or takes in more heat than it can release (Mora-Rodriguez, 2012). In conclusion, the human body is remarkable at maintaining a point of equilibrium through homeostasis. Thermoregulation is proven through athletics. Homeostasis keeps an athlete’s body at a stable core temperature despite being in a hot and humid environment. Through thermoregulation, homeostasis provides the body with a way to adjust to various temperatures and environments. Homeostasis is proof humans were created
