Do you avoid exercising outside because of the cold air? Afraid of how it's going to affect your lungs? One expert said it's ok as long as you take precautions.

There is no magic temperature to say its' too cold to exercise outside, it depends on each person’s tolerance. For some people, breathing cold air can cause pain.

"When you are exposed to cold air and you feel tightness, it may be as simple as your throat may not be used to temperature changes,” said Pediatrician Dr. Kallanna Manjunath.

A gradual exposure to outdoor air can help increase your tolerance.

"Exposed gradually and begin exercise or you may have an asthma like illness where cold air result inflammation as well as contraction in muscle around airway tube that may cause a tightness in your chest,” said Dr. Manjunath.

Some folks choose to cover their mouth when it’s below a certain temperature, but not everyone has to.

Dr. Manjunath said, “It varies from person to person I've seen people jogging without any difficulty when it's minus twenty, minus thirty but other have difficulties early on. You need to know what your own normal symptoms are. The colder the air, the more protection you want to have. At least in the beginning phase of exercise. Once body gets used to it, you can unlayer."

Well most can manage exercising outside, asthmatics need to be careful to take precautions to avoid bringing on an attack.

"In very minority of patients, it could be a dangerous thing. In most people, as long as you recognize symptoms early and get appropriate medical intervention, you should be able to resume normal activity in cold air,” said Dr. Manjunath.
