When the weather turns cold or the winter is cold and dry, breathing in cold air will make the condition worse and need to use asthma medicine.
Patients with asthma are very sensitive to dry air, so in winter, it is necessary to humidify and warm the air more to reduce the onset of asthma attacks due to the breakdown of cells in the airways, releasing substances. chemical mediators that constrict the airways and trigger asthma attacks.
