Gently sniff a small amount of black pepper
Look toward a bright light if you are naturally light-sensitive
Tickling the inside of your nose with a clean tissue or cotton swab
Smelling strong odors like peppermint or perfume
Inhaling dry air briefly
Taking a deep breath and exhaling sharply through the nose
Rubbing the roof of your mouth with your tongue
Drinking a cold beverage quickly
Using a saline nasal spray
Blowing your nose gently
