Aspirin is a pharmaceutical drug often used to treat pain, fever, and inflammation. A drug is any substance (other than food that provides nutritional support) that, when inhaled, injected, smoked, consumed, absorbed via a patch on the skin, or dissolved under the tongue causes a physiological change in the body.
In a crisis, the sympathetic division of your autonomic nervous system (ANS) mobilizes your body for action, directing your adrenal glands to release the stress hormone epinephrine (adrenaline) and norepinephrine (noradrenaline). To provide energy, your liver pours extra sugar into your bloodstream.
When one faces a dangerous or stressful situation, the sympathetic nervous system is automatically activated without conscious control. Stimulation of the adrenal glands to release norepinephrine and epinephrine, which are responsible for the cascade of reactions associated with stress.
