The use of smelling salts is nothing new. These chemical-containing wake-up aids have been used in some form for hundreds of years, most often to restore consciousness in people who have fainted. Today, smelling salts can still be used for that purpose, but they are also utilized by athletes and gym-goers as a stimulant to boost alertness and focus. Let SPY guide you through what smelling salts are, their origin, how they work and the potential dangers of using them to see if smelling salts are worth adding to your routine.
What Are Smelling Salts?
Smelling salts, also known as ammonia inhalants, spirit of hartshorn or sal volatil, are compounds that contain the active ingredient ammonium carbonate. This ammonia gas–producing ingredient is often combined with some kind of perfume to mask the gas’s rather overpowering smell.
You may also find alternative smelling salts, better known as aromatic spirits of ammonia, which use diluted ammonia instead of ammonium carbonate, with ethanol and perfume to produce a similar, gas-fueled stimulation. This preparation is more common in over-the-counter products available today.
How Do Smelling Salts Work?
The action of smelling salts is based on the human body’s natural reaction to ammonia gas. When sniffed or breathed in, the ammonia gas causes irritation to the membranes in the nostrils and lungs, triggering a near-involuntary inhalation reflex. It’s this inhalation that increases the amount of air, including oxygen, inside the lungs and potentially jolts the body awake. This oxygen-led stimulation is the main goal of smelling salts and why they are sought after for reviving consciousness or stimulating alertness.
The History of Smelling Salts
The origin of smelling salts can be traced back to the 13th century, beginning a journey that saw its use in several functions, including textile dyers, medicine and baking. Fast forward to Britain’s Victorian era and smelling salts were used as a medical treatment, carried by police and emergency workers to revive anyone who fainted.
In the 20th century, boxers frequently used smelling salts to remain alert and prevent/delay the impact of hard hits (although this is now banned in modern day competition). Today, smelling salts have mostly been replaced by alternative methods when it comes to dealing with fainting. However, the use of smelling salts can still be observed in many sports (including football and hockey), and by athletes such as Tom Brady and Peyton Manning, who have been observed using smelling salts for their focusing impact.
Are Smelling Salts Safe?
There are no scientific reports to suggest that the use of smelling salts in the capacity seen in sports or gyms results in any adverse health issues. However, given that prolonged exposure to concentrated ammonia gas can have severe negative health implications, it’s likely that the comparatively small dose of ammonia gas and the short-term exposure is what makes smelling salts OK for use.
Because of the potential issues if mistreated, it’s always important to follow the directions specified on the product. This includes maintaining correct distances and not overusing the product. In terms of legality, it’s also worth mentioning that, in the majority of sports, smelling salts are perfectly legal for use.
