Smelling salts

Chemical compounds used to arouse consciousness by irritating the mucous membranes of the nose and lungs, typically containing ammonia. This irritation triggers an inhalation reflex that increases breathing and heart rate, aiding in the revival of someone who has fainted or is feeling lightheaded. Smelling salts are commonly used in first aid kits, sports medicine, and by medical professionals to quickly revive or stimulate individuals.
