I've just finished reading all of the posts. I think 90% of them seem to be people with the can't yawn / take deep breath problem, and the rest seem to be generic asthma / shortness of breath. So here we go - for the yawning/deep breath problem (YDB):
People Affected:
Age: 13 - 60
Sex: M & F
Smoke: Smokers and Non smokers
Pets: Both people with and without
Execise: Common in people who do regular execise, those who don't
Diet: All ranges of diet, from organic veg only to 8 diet pepsi's a day
Stress: Affects both people prone to panic / anxiety and those who are less so. May be more common among more anxious people.
Example of symptoms:
Feel urge to take deep-breath/yawn to get "satisfaction", however often yawn/deep-breath does not "work" - i.e. no satifaction gained. When eventaully breath/yawn does "work", often only a few minutes (or less) passes before the urge to take a deep breath/yawn returns, and the cycle repeats.
Possible triggers / factors affecting the problem
1. Stress - Seems to be a common theme. Extreme stress seems to trigger or heighten the problem, however problem can go on daily for years, which suggests that it stress not the primary cause.
In some cases, yawning problem starts randomly, where the sufferer is under little or no stress; the problem itself then causes stress, which heightens the problem, possibly causing a panic attack, further heightening the problem. This is not always the case. I personally have never had a anything remotely resembling a panic attack, and I have never been concerned about having this yawning problem, I just find it annoying. Stress may be a trigger and may heighten the problem, but it doesn't fit with causing the problem. This is backed up by the consistency of the physiological symptoms.
2. Sleep
People report having the issue while asleep and it waking them up, and also keeping them from going to sleep. However, some (including me) have no problem once asleep, or while going to sleep. Amount of sleep does not seem to be a factor either.
3. Execise
Some report the problem being worse after execise, some that it occurs both during and after execise; mostly people seem to report that it occurs when they are not execising, or that exercise does not affect it much either way.
4. Trapped wind / burping
Some people report that burping (releasing trapped wind from the stomach) seems to help with getting satisfaction from following yawns. Suggestions that release of trapped wind allows lungs to expand properly. This does not seem to be definitive (I know I have not noticed this)
Suggested Causes
I should also note that the Yawning Deep Breath Problem could be a symptom which can be caused by a range of different things, so it may be that what is (the root cause) for you is not the root cause for someone else. However, even in such a case, both separate causes are probably triggering the same physiological mechanism, be it in the lungs themselves, or in the brain respiritoy regulatory system (the bit of the brain that controlls breathing). Anyway, here they are:
- Mitral valve prolapse - (common heart defect, wide ranging symptoms)
- Lymes disease - (tick born infection - can have very wide ranging and diverse symptoms, although failure to take "deep satifying breath" is one. Can be hard to diagnose; chronic symptoms can appear years after infection. Is somewhat controversial, and looks like it may be used as a generic "catch all" for hard to diagnose chronic problems).
- Iron deficiency anemia - (enough hemoglobin cannot be formed due to lack of iron in the diet; 10 times more prevalent in women than men; Up to 20% of US women of child brearing age may have this.) Note: If this were the sole cause of the yawning problem, we would expect to see ~10 times more women on these posts than men.
- Asthma / Allergies: Possibly a mild form of asthma, although most report than inhalers / asthma meds have no effect whatsoever; also not linked with coughing or wheezing. Allergen
- Vocal Chord dysfunction (VCD): (lesser known problem where vocal chords constrict the breathing. Treated by speech therapy, among other things.)
- Misaligned ribs / musculo skeletal problem with the ribcage. Some people report that 5 mins with a chiropractor fixed the problem, as their ribs were misaligned. While I do have a prblem with my ribs (so this is an appealing suggestion), I would imagine that it would show up on a chest xray, which for me (and many others) it apparently doesn't.
So there you go.
