The term "life hormone" isn't a specific, universally recognized medical term. However, based on the context and the provided reference, it likely refers to hormones crucial for survival and essential bodily functions, primarily those secreted by the adrenal gland: epinephrine (adrenaline), norepinephrine (noradrenaline), and cortisol.
These hormones play vital roles in:
-
Epinephrine (Adrenaline): Often called the "fight or flight" hormone, epinephrine is released in response to stress or danger. It increases heart rate, blood pressure, and energy supplies to muscles, preparing the body for action. It's critically important in life-threatening situations like severe allergic reactions (anaphylaxis), where an epinephrine auto-injector (EpiPen) can be life-saving.
-
Norepinephrine (Noradrenaline): Similar to epinephrine, norepinephrine also increases heart rate and blood pressure. It also plays a role in attention, alertness, and mood regulation. Low levels of norepinephrine can contribute to conditions like depression.
-
Cortisol: Known as the "stress hormone," cortisol regulates various bodily functions, including metabolism, immune response, and blood sugar levels. While essential for managing stress, chronically high cortisol levels can have negative health consequences. However, in acute situations where the body is under stress (e.g., severe illness or injury), cortisol's anti-inflammatory and glucose-regulating effects are crucial for survival.
Therefore, while not a formal term, "life hormone" is best understood as encompassing these three adrenal hormones because of their direct impact on survival and overall health.
