Slow down your breathing by exhaling for a count of 4. Breathe in about 75% of a normal inhalation. Shape your mouth into an O and try to keep your voice box open. Contract your abdominal muscles to force air up through your mouth. You should make a soft “huff” sound. Inhale a quick, shallow breath and make another “huff” sound.
Take big, deep breaths in the cold air. Make sure the air reaches down into your lungs.
Alternately, ask someone to blow cigarette smoke in your face. Breathe in through your mouth to bring the smoke into your lungs. If you are not a smoker, this may cause you to cough. If you are a smoker, this may not be very effective. However, remember, even if you’re a smoker, the smoke can be dangerous for you.
Find something that smells really awful, like rotting food or feces. You may have a reaction to the smell that includes gagging and coughing.
