Are Smelling Salts Dangerous? Risks, Safety & Myths | Fitness Fox

Smelling salts (ammonia inhalants) can irritate the nose, throat, lungs and eyes, and may cause chemical burns at close range or with repeated misuse. They don’t “fix” concussion or fainting, and any alertness boost is short-lived. If you choose to use them, keep the container about 10–15 cm (4–6 in) from your nose, waft briefly, and avoid frequent or deep inhalations. People with asthma/respiratory disease, eye problems, or recent head/neck injury should avoid them.

What smelling salts are—and how they work

Smelling salts release a small amount of ammonia gas (NH₃). When you waft that vapour near your nose, it irritates the upper airways, triggering a reflex inhalation and a brief sympathetic “wake-up” jolt. They can raise alertness for a moment, but they’re not a real performance enhancer and they’re not a medical treatment. 

Are smelling salts dangerous?

Short exposures, used sparingly and at a distance, are generally tolerated for healthy adults. But ammonia is a corrosive irritant: high doses or misuse can injure tissues, and even lower exposures are uncomfortable for many people. Reputable clinical and toxicology sources describe the following risks: airway irritation and bronchospasm, eye watering/burns, skin/mucosal irritation, and—at sufficiently high exposures—lung damage

Risk matrix (fast scan)

System

What can go wrong

Why it happens

Reduce the risk

Respiratory

Coughing, wheeze/bronchospasm; at high or prolonged exposure, lung injury

Ammonia is a strong upper-airway irritant; high concentrations are corrosive

Avoid if you have asthma/COPD; brief waft only; never deep or continuous inhalation. 

Eyes

Watering, pain, chemical burns or temporary vision issues at close range/splash

Corrosive to ocular tissue

Keep bottle 10–15 cm away; point away from eyes; close promptly. 

Nose/skin

Stinging, irritation, chemical burns with strong/close or repeated exposures

Alkaline irritation/burn

Waft at distance; avoid touching liquid/powder; don’t overuse.

Neuro/heart

Short spike in HR/BP; can mask symptoms after head impacts

Reflex arousal + adrenergic surge

Do not use after head/neck trauma; follow concussion protocols. 

Bottom line: “Safe” use is brief, distant, and infrequent—and still not appropriate for everyone.

Myths vs facts

Myth

Fact

“Smelling salts revive knocked-out athletes.”

Modern sports medicine says don’t use ammonia to assess or “wake” someone with a head injury; it can mask symptoms and complicate evaluation. Remove from play and seek medical care. 

“They’re a legit performance booster.”

Evidence for meaningful performance gains is limited; salts mainly create a brief arousal cue. Me

“If some is good, more is better.”

Overuse increases risk of airway/eye injury and burns; deep inhalations are a hard no

“They’re safe for everyone.”

People with asthma/COPD, eye disease/surgery, or those under concussion evaluation should avoid them. 


Who should not use smelling salts

  • Anyone with asthma, COPD, or reactive airway disease. 

  • Anyone with head/neck injury or suspected concussion—don’t use salts to “check if you’re ok.” 

  • People with eye disease or recent eye/face surgery (vapour exposure risk).

  • Children/adolescents without clinical guidance. (General poison-safety rules apply.) 

Safe-use checklist (if you still choose to use them)

This isn’t medical advice—just safety basics drawn from toxicology and clinical guidance.

  1. Read and follow the label. Activation and handling differ by brand; some require adding water once, others are ready to use.

  2. Distance matters. Open the bottle away from your face, then waft vapour from ~10–15 cm (4–6 in). Never place under the nostrils or directly on skin. 

  3. Duration & frequency. One brief whiff only; don’t inhale deeply or repeatedly set after set.

  4. If exposed at close range (eyes/skin): move to fresh air, rinse with water copiously; seek care if irritation persists or breathing is difficult.

  5. Storage & access. Keep sealed, upright, room temp; away from kids/pets.

Rules & headlines (so you don’t get caught out)

In August 2025, the NFL changed its game-day policy: teams cannot supply smelling salts during games, though players may use their own if they choose. The league cited medical concerns—including the potential to mask neurological symptoms—in response to an FDA warning; the NFLPA issued a clarification for players. Policies in other leagues/federations vary. Always check your rulebook.

Do they help performance?

There’s no robust evidence that ammonia inhalants improve race times, strength outputs, or endurance in a consistent way. You might feel more alert in the moment, but that’s different from measurable, repeatable performance change—and the trade-offs (irritation, dependency habit) aren’t worth it for most people. 

Smarter alternatives for a pre-lift “switch on”

  • Caffeine (within your personal tolerance and sport rules).

  • Breath priming (2–3 fast nasal inhales + forceful exhale).

  • Music/psych-up ritual (consistent cues beat chemical spikes).

  • Good warm-up (ramp HR, prep the movement pattern).

FAQs

Are smelling salts dangerous?

  • They can be if misused: ammonia can irritate or burn the nose/eyes/airways, and high or prolonged exposure risks lung injury. Use briefly, at ~10–15 cm, or skip entirely if you have respiratory disease. 

Do smelling salts help you lift more?

  • Not reliably. They may boost alertness, but consistent, meaningful performance gains aren’t well supported by evidence. 

Are smelling salts allowed in competition?

  • Depends. Example: in Aug 2025 the NFL barred team-provided salts on game day, though players can bring their own. Check your federation or league rules. 

Who should avoid them?

  • People with asthma/COPD, eye problems/surgery, or anyone with recent head/neck injury. Kids should not use them without medical guidance. 

What if I get ammonia in my eyes or on my skin?

  • Go to fresh air; rinse eyes/skin with water; seek care if irritation persists or if breathing is difficult.
