By the way, the breathing exercise though the nostrils is called "Pranayam" and is a yoga technique. I will try it - used to do it years ago but never thought to do it again to stop the yawning. For me, sometimes after eating, I yawn and yawn and am very tired to the point of sometimes falling asleep sitting up - or in meetings at work. Not a good thing.

Kapalbhati from my post of March 11,2010 will help with lack of breath. Do about 20 to 30 strokes of kapabhati, to expel the stale air in the lungs.
Anulom vilom will help with the headache and racing heart.
Yes, I too am a very fit (love cycling heaps) healthy young (39) woman who practices the yoga breathing techniques, yoga and lead a calm peaceful contended life. I first had this yawning to get a satisfying breath in my early 20's. When I queried the doctor then he said it was because I was over tired. Since then I have probably had 2 episodes of lack of breath each year. My most recent one started a week ago and is giving me a headache and a racing/thumping heart beat every so often. I finally thought 'gee, maybe there really is something medically wrong with me and perhaps I should go to the doctor again". Firstly I thought I would undertake some internet research, and I don't feel so silly now, there are so many fit young healthy women out there just like me with the same breathing issues. At least I have some information to go with now when I go to the doctor.
I have the same thing. They are symptoms of hyperventilation. Which are not fun, but at least it isn't something incredibly life threatening. There are more symptoms associated with hyperventilation, but not everyone is affected by all of them. For my entire life the doctors thought I had asthma and prescribed me 100 different medications that didn't do anything. Doing some research online I found that I regularly fit 12 of the 14 symptoms of hype (as in at least 4 times per week) and every once in a while i get the 13th. I guess I must have it pretty bad. I just hope I find something to make it better. I really began to notice it when the humidity started to get bad. I knew something was wrong because moderate humidity is supposed to be really good for asthma. This may just be me, but I don't have trouble breathing when I run; I actually breath better directly after. I ship off to USMC basic soon, so I am h3ll bent on finding something to help before that, just in case something were to happen to me.
Here is the list of symptoms. See for yourself if this sounds like it could be your problem. (I starred the ones I have)
*Feeling anxious, nervous, or tense.
*Frequent sighing or yawning.
*Feeling that you can't get enough air (air hunger) or need to sit up to breathe.
*A pounding and racing heartbeat.
*Problems with balance, lightheadedness, or vertigo.
Numbness or tingling in the hands, feet, or around the mouth.
*Chest tightness, fullness, pressure, tenderness, or pain.
Other symptoms may occur less frequently, and you may not realize they are directly related to hyperventilation. These symptoms can include:
*Headache.
*Gas, bloating, or burping.
*Twitching.
*Sweating.
*Vision changes, such as blurred vision or tunnel vision.
*Problems with concentration or memory.
Loss of consciousness (fainting). (the only one I have never had)
Because of the tunnel vision, concentration/memory loss, and twitching I really thought I had ADHD (all shared symptoms). I am starting to doubt that now.
Again apparently all of these symptoms do not affect everyone, and when they do you may not even know it is related. Also I am not a doctor, so don't take my word for it. Look it up!
