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.
At the onset of a panic attack, the sympathetic nervous system causes your muscles to tense up. It also sends a message to your adrenal glands to release the hormone adrenaline. This adrenaline has many effects on your body: It produces sweat and increases your heart rate.
