Asthma is a lung condition that causes swelling of the airways. It can make breathing difficult and trigger coughing, wheezing and shortness of breath. It's the most common chronic disease among children, though it affects adults, as well. More than 262 million people globally are affected by asthma and more than 461,000 have died due to the disease, according to the World Health Organization.

While there is no cure for asthma, symptoms can be treated, says Dr. John Costello, a pulmonologist at Mayo Clinic Healthcare in London.
