Strange Effects Of A Sustained Running Routine

Runny Nose

It is common for people who exercise to have running noses, especially if the exercise is taking place outside instead of inside a gym, and it can get worse during the times of year when allergens are high or under cold climate conditions. The allergens irritate the nasal passages which cause mucus production to increase and the heat generated by running causes the mucus to run down the nose. Some claim that nitrogen dioxide found in car exhaust is a significant trigger because those who exercise inside appear to have fewer occurrences of runny noses. Though a constant runny nose can be annoying, it is not harmful, and it can be managed with minimal effort.
