Home treatment may help you control your breathing and stop hyperventilation. First, sit down and concentrate on your breathing.
Breathe through pursed lips, as if you are whistling, or pinch one nostril and breathe through your nose. It is harder to hyperventilate when you breathe through your nose or pursed lips, because you can't move as much air.
Slow your breathing to 1 breath every 5 seconds, or slow enough that symptoms gradually go away.
Try belly-breathing, which fills your lungs fully, slows your breathing rate, and helps you relax.
Place one hand on your belly just below the ribs. Place the other hand on your chest. You can do this while standing, but it may be more comfortable while you are lying on the floor with your knees bent.
Take a deep breath through your nose. As you inhale, let your belly push your hand out. Keep your chest still.
As you exhale through pursed lips, feel your hand go down. Use the hand on your belly to help you push all the air out. Take your time exhaling.
Repeat these steps 3 to 10 times. Take your time with each breath.
Always try measures to control your breathing or belly-breathe first. If these techniques don't work and you don't have other health problems, you might try breathing in and out of a paper bag that covers your nose and mouth.
Using a paper bag
Use a paper bag to control your breathing. Take 6 to 12 easy, natural breaths, with a small paper bag held over your mouth and nose. Then remove the bag from your nose and mouth and take easy, natural breaths.
