Homeostasis refers to your body’s remarkable ability to maintain a stable internal environment even when external conditions change. It’s the reason your body temperature stays around 98.6°F whether it’s freezing or sweltering outside.
How Homeostasis Works:
The endocrine system plays a central role in homeostasis by using hormones to communicate between organs and adjust bodily functions. These adjustments happen through negative feedback loops – when something goes too high, the body responds by bringing it down, and vice versa.
Examples of Homeostasis:
Blood sugar regulation by insulin and glucagon keeps glucose levels stable. Body temperature regulation through metabolism and sweating maintains steady internal temperature. Blood pressure control through various hormones keeps it within normal ranges. Fluid balance through hormones like ADH (antidiuretic hormone) regulates hydration.
When Homeostasis Fails:
When hormonal balance is disrupted, homeostasis can be affected, leading to various symptoms and health conditions. For example, thyroid disorders disrupt temperature and metabolism regulation, while insulin resistance affects blood sugar homeostasis.
