Thank you, cold drinks and air always bother me when it's bad allergy season. My asthma is under control but when I drink cold ice tea I cough my brains out! I appreciate your info on the post above. I thought I was crazy. It's been going on since I was 14 almost 20 years now..
For asthmatics (especially those with exercise-enduced), cold air or cold beverages (especially thicker ones, like milk shakes or smoothies) can cause coughing and an increase in asthma-symptoms.
Avoid cold water, it's bad for your digestion anyway, and go for room-temp.
If you've never had breathing problems before, I wouldn't worry too much about it, but you can always see a doctor.
