Exercise Induced Asthma Defined And Explained
So what is exercise induced asthma and how does it differ from other types of asthma? In a sense exercise induced asthma is not that much different from the more common allergic asthma, only the circumstances where it can present itself differs. Obviously Exercise induced asthma or EIA only presents itself when there is exercise or activities which require physical strength involved.
Another thing that sets EIA apart from any other types of asthma is in its cause. While inflammation and irritation are still the end result EIA is mainly induced by rapid heat exchange which is the process of rapid cooling and reheating of the respiratory system which eventually causes the irritation. When we undergo activities that require stamina or strength our breathing tends to become harder this is to adjust for the amount of oxygen that your body needs, which also leads the airways to dry up faster, our body then compensates by quickly reheating and producing enzymes to moisten the airways.
While for those without asthma this may not pose as a problem, for asthmatics, this mechanism of heating and cooling irritates the oversensitive respiratory system, causing inflammation and irritation which then leads to the onset of symptoms and attacks. The symptoms associated with EIA include; difficulty in breathing, light-headed (signifying the lack of oxygen going through the system), extreme fatigue which is not directly associated with the difficulty level of the activity, coughing, wheezing and pain in the chest which can range from moderately manageable to terrifying (pain is similar to having a heart attack).
EIA is also shown to be occurring more during cold weathers. In colder climates, participating in activities such as winter sports (skiing and hockey), EIA is more likely to make an appearance as opposed to summer based sports activities such as volleyball or swimming. Swimming is considered to be the safest sport for exercise induced asthmatics, while it is not readily explained why. One theory is that it may have something do with better moisture retention abilities of the body when participating in water based activities.
Wherever you may go, doctors will not recommend stopping exercise for asthma, even if it is the cause of your symptoms. Exercise is even encouraged as it strengthens your body's immune system and makes you more resilient to asthma episodes. A few precautionary measures such as warming up before the exercise, taking your medication before exercising, can help. Talk to your doctor about it as he or she may be able to give you a clearer picture of what kinds of exercises you may be able to do. Your doctor may also give you more precautionary measures so as for you to fully enjoy exercising and staying healthy.
