what do smelling salts do for nfl players

Smelling salts for NFL players work by releasing ammonia gas when a packet is broken or snapped. The strong, pungent odor irritates the mucous membranes in the nose and lungs, triggering an involuntary inhalation reflex. This reflex increases the breathing rate, heart rate, and blood flow to the brain, which results in a sudden boost in alertness and energy. Players use smelling salts primarily for a quick burst of energy and mental focus. The ammonia triggers the body's fight-or-flight response, temporarily increasing adrenaline and alertness. This helps players get "in the zone" before plays or after a big hit to regain sharpness. The effect is likened to a slap in the face that wakes them up instantly. However, smelling salts do not treat injuries and are not a substitute for proper medical evaluation. There are safety concerns because the ammonia can mask symptoms of concussion, which is why recently the NFL has restricted teams from distributing smelling salts to players following warnings from medical and regulatory authorities. In summary, smelling salts offer NFL players a temporary boost in alertness and energy, helping them focus and react quickly on the field, but their use poses potential risks, especially in relation to head injuries and concussions.
