There are a few babies who are born with asthma, and asthma can also develop at any time in life. Asthma is most likely to develop in childhood. Ast

Exercise is the second most common trigger of asthma after allergies. Sixty to ninety percent of all asthmatics are affected by exercise. An asthmatic who is exercising for five minutes at seventy percent of his or her capacity can trigger asthma. Exercise and other strenuous activities that trigger asthma occur because of the air quality entering the lungs. (American 43). When any one exercises, non-asthmatics as well as asthmatics, rapid breathing occurs, generally through the mouth. The air that is reaching the lungs of an asthmatic has not had a chance to be warmed and humidified by the nose as it is when normal breathing occurs through the nose. This unproperly warmed air may cause a spasm in the lungs. If the air in the surrounding environment is cold or dry then there is more of a chance that the air passages will go into spasm. Therefore, asthmatics should avoid activities such as ice skating or skiing. The symptoms of exercise-induced asthma usually will subside within a few minutes, but they can last for a few hours. This time can be delicate for an asthmatic. Medication may be necessary to prevent the condition from deteriorating to dangerous levels (brown 27).

Many factors can make exercise for asthmatics possible. Those factors include using medications, choosing the right type of exercise for the individual, exercising in proper environmental conditions, and using proper breathing techniques. It is proven that using proper bronchiodiolaters, commonly known as inhalers (medication), twenty to thirty minutes before exercise will reduce the chance of asthmatic symptoms occurring. In addition, a thorough warm-up and cool-down greatly reduces the chances of developing asthma symptoms (Haas 44). Next, the right type of exercise is necessary. If the exercise is too hard or strenuous, the asthmatic will be unable to perform adequately and will be apprehensive to continue this activity on a regular basis. The activity must be one that the participant can do for at least twenty minutes at a time three days a week. Anything under this will not sustain many benefits. The activity must be performed in a proper environment since the leading trigger of asthma is allergies (Hirt 102). If it is known that a certain time of year is a bad allergy season for an asthmatic then the activity should not take place outdoors or in an area where the allergen will affect the asthmatic. Even if all these elements are followed, the asthmatic may still feel a point of breathlessness, within the first few minutes of exercise. This time is know as the second wind stage (Harrington 12)
