Lo que podría significar tu bostezo constante

The user posted that for a few days she felt the need to yawn or take a deep breath every few minutes.. She felt the same urge throughout the day, whether she was tired or not. She wasn't particularly stressed about anything. But she had had a similar episode earlier in the year, which lasted for about two months.

Why do we yawn?

Patient 1 reminded us of the popular belief that yawning occurs when the brain needs more oxygen. In fact, recent research suggests that yawning - a wide opening of the mouth, an involuntary intake of breath, and a short breathing out - occurs when the main source of stimulation in a person's environment is no longer able to sustain their attention. We call this boredom.

Boredom induces drowsiness when the brain activates the sleep generating system. Tests on oxygen levels of people before and after they yawn show no change, and it's suggested that the reason for yawning is actually to cool the brain down.

Other research suggests that contagious yawning (yawning when you see another person yawn) is related to activation of the amygdala area (a group of cells low down on the side of the brain). Quite what this has to do with the user's problem, I'm not sure. But it does demonstrate what a complex activity yawning is.

The good news is that by and large excessive yawning is not a sign of any serious medical condition. Rarely, it can be associated with epilepsia, esclerosis múltiple, o accidente cerebrovascular. Unless you want to get me drummed out of the GP Brownies, please don't think you have any of these illnesses just because you get excessive yawning; my advice to you is to read our associated leaflets and only seek medical advice if the yawning is associated with other features of these conditions.

Patient 2 described the user's need to breathe deeply as 'air hunger' and this is a very good description. He also called it pseudo-dyspnoea, which means false shortness of breath. This term is used when a person's falta de aliento isn't due to heart or lung disorders or any other demonstrable physical problem. It often gets better with exercise, which is the complete reverse of true dyspnoea, which improves with rest. Patient 3 and Patient 4 also used the term chronic hyperventilation syndrome, which refers to a long-term condition in which the person breathes too deeply or too rapidly.

So what can be done about all this? Some of our posters thought allergy played a part. Patient 5 was helped by a milk-free diet and wondered if it was all to do with mucus in the respiratory system. Patient 6 benefited from decongestant tablets. Others, such as Patient 7 and Patient 8 wondered whether enfermedad por reflujo gastroesofágico (GORD) or hernia de hiato was a cause. They were helped by measures to reduce acid reflux, such as antacids, acid suppression medication such as omeprazole, and raising the head-end of the bed.

Patient 9 found that cutting down on coffee helped the hyperventilation. It's worth a try. Although, scientists have found that caffeine stimulates the arousal system, so this could make the yawning worse!

Inevitably, with all this talk of breathing, asma raised its ugly head. However, Patient 10 and several other posters found asthma inhalers unhelpful and tests for asthma were normal. Patient 11 knew what asthma felt like, and this wasn't it.

Patient 12 had read about air hunger being a feature of anaemia and wondered whether iron tablets would help. However, Patient 13 said he had this problem and his iron levels were fine. He counselled against taking iron tablets unless his doctor diagnosed iron deficiency with a blood test. You won't be surprised that I agree with him!

Patient 14 and Patient 15 found treatment from a chiropractor helpful. Patient 16 benefited from homeopathy. And Patient 17 swore by raw ginger. None of these have any medical science behind them but my attitude as ever is that if people have found conventional medicine unhelpful, and alternative medicine has something to offer, give it a try (providing it doesn't do you any harm).

Some posts I found fascinating focused on attempts to alter the patterns of breathing. Patient 18 pointed out that breathing was an involuntary activity and if the mind started to concentrate on the activity of the chest muscles moving air in and out of the lungs this could become an obsession. She suggested imagining an 'automatic breathing switch' which you turned on to let the body do its own thing, while your brain went off to do something else. Patient 19 also recommended distraction as a way of reducing symptoms.

Patient 20 had been helped by diaphragm exercises and Patient 21 recommended concentrating on using your abdominal muscles to breathe. Patient 22 pointed out that there were several YouTube videos which demonstrated this.

Patient 23 felt that psychological problems such as ansiedad were often a cause, and that by altering the pattern of breathing, you were changing the balance between the oxygen you breathed in and the carbon dioxide you breathed out, which just aggravated the feeling that you are not getting enough air. Psychological problems such as anxiety and depression featured frequently, although Patient 24 and several other posters found anti-anxiety medicines such as benzodiazepines unhelpful. These are in any case meant for short-term use as there is a considerable risk of dependency.

The poster who people found the most helpful seemed to be Patient 25, who recounted his experiences with the Buteyko breathing technique. Although intended for asthma and enfermedad pulmonar obstructiva crónica, many posters with air hunger and excessive yawning found this helpful.

Clearly, it's a big problem (280 posters and counting). Many people were unimpressed by the help they got from the medical profession: I think this just reflects the fact that doctors need to increase their knowledge base about the link between the brain and the lungs and the body systems that control breathing and yawning. There are probably several factors involved, both psychological and physical, and we are not going to get a 'one size fits all' solution.
