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.
Your vagus nerve initiates your bodyâs relaxation response. When under stress, your sympathetic nervous system (the âflight or fightâ system) dumps stress hormones into your body. Your vagus nerve and parasympathetic nervous system releases acetylcholine to calm down this stress response, allowing you to relax.
