From an Email I just wrote to the Devo crew, but good advice to all:
Finally at this time of year, particularly with the traveling that occurs around the holidays, we are often more susceptible to illness than normal because of the introduction of new pathogens into our environment. Having watched many athletes struggle with sickness for extended periods of time in the winter (sometimes months) because they never give their body a chance to recover, I want to encourage everyone to skip training or races and take time off if they are sick. Compounding this in Fairbanks is the fact that we have lots of cold, dry weather which when combined with respiratory infections, greatly increases an individuals chances of developing Exercise Induced Asthma. Having seen a couple of athletes over the past two years work with EIA, I can assure you that it is a nuisance to deal with. In the Handbook of Sports Medicine and Science of Cross Country Skiing, put out by the International Ski Federation (FIS), I have a sentence highlighted from the chapter entitled ‘Medical Aspects’ written by Ola Ronsen, MD:
“If one particualar piece of advice should be emphasized it must be the precaution of not exercising in cold weather while having symptoms of respiratory infections - even for several days after the fever and fatigue has passed.” (p.121)
And a little further thought (not in the email):
Often times people ask about cold weather masks for training. Personally, while I don’t have one (yet) I think they are a good idea. The same chapter mentioned above, also mentions that the risk factors “contributing to EIA are: high intensity of exercise, exposure to cold and dry air, respiratory infections, allergens and dust, air pollution, fatigue and stress.” (p. 122) While I (a ski coach, not a pulmonary medical specialist) don’t think training with a heat/moisture exchange mask is a miracle cure-all or a replacement for avoiding other risk factors (such as training in polluted areas (like the valleys at certain times during the winter), or ignoring the above advice about resting or training inside when recovering from illness), it seems logical to minimize the risk factors involved. While the masks have only been available overseas in the past, Beaver Sports has begun carrying them this year for about $45. At the very least, breathing through a neck warmer or balaclava on the coldest days is highly recommended.
