What Are Smelling Salts?
Smelling salts are compounds, typically containing ammonium carbonate, that release ammonia gas when exposed to air. This gas has a very strong, pungent odor that stimulates the nasal passages and respiratory system.
What Do Smelling Salts Do to the Body?
When inhaled, smelling salts trigger a reflexive inhalation response, which leads to:
-
Increased Oxygen Intake – The sharp inhalation increases oxygen flow to the brain.
-
Heightened Alertness – The irritant effect causes the body to become more alert by activating the sympathetic nervous system (similar to a mild fight-or-flight response).
-
Increased Heart Rate and Blood Pressure – This temporary stimulation can make someone feel more awake and energized.
Why Are They Used in Performance-Related Activities?
Athletes, particularly in weightlifting, football, hockey, and combat sports, use smelling salts to:
• Boost Mental Focus – The sudden stimulation helps improve concentration before a big lift or game.
• Increase Strength Output – Some studies suggest smelling salts can temporarily enhance neuromuscular activation, leading to greater power output.
• Prevent Fainting or Fatigue – They can help revive a player who is groggy or sluggish.
While they provide short-term alertness, they do not directly improve strength or endurance—they simply prime the body for peak performance by shocking the nervous system.
Are Smelling Salts Safe?
• Short-term use is generally safe, but excessive or frequent use can irritate the nasal passages and respiratory tract.
• Not recommended for individuals with asthma or respiratory conditions due to the potential for airway irritation.
• They do not replace proper recovery or nutrition—they are a temporary stimulant, not a long-term performance enhancer.
• Overuse can lead to dependence, where an athlete feels they need them for every performance.
Do Smelling Salts Affect Brain Performance?
Yes, but only temporarily. Smelling salts stimulate the reticular activating system (RAS) in the brainstem, which increases alertness. However, they do not enhance cognitive function, intelligence, or memory—they simply provide a short burst of mental clarity and focus.
