Experts say that asthma patients facing cold weather can cut their chances of an asthma attack if they wear a scarf over their nose and mouth.

Breathing in cold, damp air can make the airways tighten and trigger an attack in three out of four people, charity Asthma UK says. This can leave people coughing, wheezing and gasping for breath.

“…cold weather is impossible to avoid over winter, but if people have asthma, simply wrapping a scarf around their nose and mouth can warm up the air before they breathe it in, reducing their risk of having an asthma attack,” experts say.
