Is it safe for an asthmatic to migrate to a cold country?

Although cold weather can exacerbate asthma, this is most likely to occur when going from a warm building into cold air. However, the adverse effect can be minimised by using 2 to 4 puffs of a bronchodilator 10-15 minutes before going out, and by breathing through a scarf wrapped loosely across the mouth. Some patients find that an inhaled asthma medicine - Intal, or a similar product Tilade is of benefit in protecting against cold-induced asthma. Since asthma is a very common disorder, and it is readily treated with excellent medications, it would be improper to exclude immigration based on a history of asthma. Moreover, asthma is just as likely to be more of a problem in very warm countries because of exposure to dusts and organic pollutants.
