What is smelling salts gym?


Smelling salts, a pungent and powerful stimulant, have become a controversial yet intriguing tool in the realm of fitness and strength training. This article delves into the science behind smelling salts, their historical context, and their implications for performance enhancement in the gym. We will also address potential risks and provide guidance on safe usage.

Understanding Smelling Salts

1. Composition

Smelling salts, scientifically known as ammonium carbonate, are a combination of ammonia gas and water. Historically, they were derived from a mixture of ammonium carbonate and perfume.

2. Mechanism of Action

When broken or crushed, the ammonia gas is released, stimulating the nasal receptors and triggering an inhalation reflex. This reflex induces an immediate and powerful inhalation of air, leading to increased oxygen intake.

Historical Context

Smelling salts have a long history, dating back to ancient Rome, where they were used to revive unconscious individuals. They gained popularity in the 18th and 19th centuries and were even used in Victorian England to revive fainting women, leading to the term “ladies’ aid.”

Smelling Salts in the Gym: How and Why?

1. Respiratory Stimulant

The immediate effect of smelling salts is a sharp inhalation, which can provide a rapid surge of oxygen to the brain. This can potentially lead to increased alertness, focus, and a feeling of rejuvenation, especially beneficial before heavy lifts or intense physical exertion.

2. Pain Tolerance

The sharp inhalation induced by smelling salts may trigger the release of adrenaline, a hormone associated with the body’s “fight or flight” response. This surge in adrenaline can temporarily increase pain tolerance, allowing individuals to push through discomfort during a challenging workout.

3. Improved Muscle Contraction

The increased oxygen intake may lead to enhanced muscle function, as muscles rely on oxygen to perform optimally. This can result in stronger and more controlled movements during exercises.

Potential Risks and Considerations

While smelling salts can provide benefits, they are not without risks:

  1. Overstimulation: Excessive use of smelling salts can lead to overstimulation of the respiratory system, potentially causing hyperventilation or respiratory distress.
  2. Potential for Dependency: Regular reliance on smelling salts can lead to a psychological dependency, where individuals feel they cannot perform well without them.
  3. Irritation: Direct contact with smelling salts can irritate the skin, eyes, and respiratory tract. Proper handling and usage precautions are crucial.

Safe Usage Guidelines

  1. Moderation: Use smelling salts sparingly and only when necessary. Avoid using them for every workout.
  2. Adequate Ventilation: Ensure you are in a well-ventilated area to prevent inhaling excessive amounts of ammonia gas.
  3. Proper Storage: Store smelling salts in a sealed container in a cool, dry place, away from direct sunlight.
  4. Avoid Direct Contact: Never touch or rub your eyes after handling smelling salts.


Smelling salts, with their rich historical significance and potential benefits, can be a tool for enhancing focus and performance in the gym. However, their usage should be approached with caution, and moderation is key. Consulting a healthcare professional before incorporating them into your routine is advisable, especially for individuals with respiratory conditions or sensitivities. Remember, they are just one element in a comprehensive approach to fitness, which should also include balanced nutrition, proper hydration, and consistent training.
