Homeostasis

     Homeostasis is an (ideal or virtual) state of equilibrium, in which all body systems are working and interacting in an appropriate way to fulfill all the needs of the person and/or the body. For example, if you had a man planning to run a marathon in 3 months, it would take tremendous amounts of training and stress on the body. The man would need to run extreme distances every day just to get his body into shape! But, before he started this, he should probably go to the hospital and get tests done just to make sure he is physically capable of completing this task. There are also things called negative homeostasis! These are things like stress, weight, depression, and bad eating habits. These all can cause physical and emotional roller coaster effects on the human body. Viruses, and bacteria can also be a type of negative homeostasis. If you become sick, you're body temperature changes and you're immune system is working harder to return your body back to its normal internal temperature. In our group, we are going to have one guy and one girl take an ice bath in the training room. We will sit in the bath for 10-15 minutes and check our post and pre pulse, blood pressure, and temperature. This should give us a good reason toward explaining what exactly it is that homeostasis does. In this case, it is maintaining body temperature and the heart trying to beat fast enough to carry blood throughout the body even though the whole organ system and nerve system is slowing down due to the rapid change in body temperature.
