Adrenaline (also known as epinephrine) has strong scientific validation for its role in supporting the Sympathetic Nervous System (SNS). The SNS is responsible for the body's "fight or flight" response, preparing the organism to respond to stress or danger. Adrenaline is a naturally occurring catecholamine hormone and neurotransmitter produced by the adrenal medulla. Upon activation of the SNS, adrenaline is rapidly released into the bloodstream, resulting in increased heart rate, dilated airways, elevated blood pressure, and enhanced blood flow to muscles—classic sympathetic responses. These effects are well-documented in physiology and pharmacology literature. Clinically, synthetic adrenaline is used in emergency medicine to treat conditions such as anaphylaxis, cardiac arrest, and severe asthma attacks, all situations where rapid SNS activation is therapeutically desirable. Its mechanism of action involves binding to adrenergic receptors throughout the body, mediating widespread systemic effects that are essential to the acute stress response. Numerous peer-reviewed studies and decades of medical practice have confirmed adrenaline’s critical role in sympathetic nervous system function, making its use both scientifically validated and indispensable in acute care settings.
