The primary uses of smelling salts are to either:
- revive someone who has passed out or suffered a head injury
- provide a temporary boost of energy
According to research, the Food and Drug Administration (FDA) still approve the use of smelling salts to revive someone who has fainted. However, there is no proof to support their use for enhanced athletic performance.
To use smelling salts effectively, a person should hold smelling salts about 10 centimeters (cm) from the nose.
