Although winter mornings have an enticing invitation to rush out for a brisk walk, they might not be recommended for patients with respiratory illness. The cold and dry air tightens the bronchi and makes breathing so hard, which might contribute to symptoms such as wheezing, coughing, or shortness of breath, Dr. Kuldeep Kumar Grover, Head of Critical Care and Pulmonology – CK Birla Hospital, Gurugram told Financial Express.com.
“This is particularly difficult for people who suffer from asthma or COPD as the body has to work that much harder to warm up and moisten the frigid air, which strains the lungs even more,” he said.
Another concern during this time of the year would be the increase in pollution in the air. For one, pollution is relatively more common during early mornings because temperature inversions trap such pollutants as car exhaust and industrial emissions close to the ground.
“This results in a higher level of injurious particles in the atmosphere that irritate the lungs, intensify inflammation, and worsen symptoms of those who suffer from respiratory disorders. Breathing air full of such pollutants tends to make outdoor exercise more difficult and harmful for those individuals suffering from asthma or any other type of respiratory disorders,” Dr. Grover said.
Dry, cold air also adds to dehydration, which can damage the respiratory system. In this case, cold air dries out the throat and airways, making breathing uncomfortable and more difficult to do. For those who tend to be dehydrated already, such as the aged or those with chronic medical conditions, this can cause much coughing and exacerbates respiratory symptoms, he said.
“Moreover, winter is at the peak season for catching cold and flu and pneumonia infections. The cold air brings a decline in the power of the immune system so the body becomes more prone to catch these diseases. By layering up, preheating indoors before venturing outside, using scarves or masks to moisten the air, and by staying hydrated, even walks during winter can become enjoyable and safe,” he added.
