what do nfl players sniff on the sideline

NFL players use smelling salts on the sideline to help them become more alert and focused. Smelling salts are typically very strong ammonia compounds that, when inhaled, stimulate the respiratory system, increasing oxygen intake and breathing rate. The ammonia gas immediately releases into the nose of the NFL player, causing them to breathe faster and feel more alert. However, smelling salts are not the best thing for players to sniff on a regular basis, as the ammonia in the smelling salts can have an impact on the players health. It is worth noting that smelling salts are not used solely by NFL players, but also by athletes in other sports and by people in other professions.
