Asthma is a breathing disorder affecting the lungs. It causes variety of symptoms such as shortness of breath, tightness in chest, wheezing, cough and excess production of sputum. The pathogenesis of asthma is inflammation in walls of airway leading to narrowing of air passage. Basically there are two factors that may be responsible for inflammation; allergy to the inhaled particles and reaction to the atmospheric air.
Often you will notice change of weather brings about spike in asthma cases. There are more visits in emergency room during this period. So let us know the reason for asthma becoming worse during change of season or at particular time of year.
What Are The Effects Of Different Seasons On Asthma?
The symptoms of asthma in people suffering from the disease can flare up is a known fact. There are several triggers known to cause flare ups such as pollen, humidity, temperature, viruses and pollution. Let us understand how each season has its own reason to cause aggravation of asthma symptoms in people prone to this condition.
- Fall: Fall is the season between winter and summer. During this season the weather becomes cooler. The cold air in asthmatics can cause tightness in the chest which can lead to attacks of asthma in people suffering from the disease. The episodes of asthma attack are not entirely to be blamed for cooler weather. The other reason for this is rise in cases of cold and flu during this period of year. The flu virus is active which causes running nose and all other symptoms of upper respiratory tract infection. Although anyone can catch the virus and suffer from discomforting symptoms of flu, for an asthmatic, respiratory tract infection can aggravate the inflammation in lungs to such an extent that patient experiences a spike in wheezing, cough, breathing difficulty more than a normal person who is not an asthmatic patient. Allergens are another problem during fall for asthmatics. Ragweed starts growing during the end of fall in certain parts of the globe. The pollen released from ragweed can become nightmare for asthmatics if they are sensitive to this allergen.
- Winter months: Flare up of asthmatic attacks is common in winter months. The cold dry atmospheric air can aggravate asthmatic attack, especially when you are exercising. However, it is not only exercising, some people may only start wheezing if they are exposed to cold dry air of winter. It is not only the outside problem. Even staying indoors can aggravate episode of asthma. The smoke released from the fire place can cause inflammation and irritation in the air passage triggering and asthmatic attack in susceptible persons.
- Spring: Spring season is the pollen season in many parts of the world. For people suffering from asthma pollen season can increase the asthmatic attacks. Pollen allergy causes flu like symptoms. In asthmatics it can aggravate the condition.
- Summer: Although summer months are relief season for asthmatics, as the episodes of asthma is low. But then too some people may suffer from asthma and wheezing. This may result from high pollution in atmosphere and increased humidity.
- Rainy season: Often cases of asthma increase in rainy months in certain parts of world. Too much moisture, increased amount of molds and fungal spores as well as pollen are troublesome for patients suffering from asthma. During monsoon there are increased incidences of viral infection. This is an aggravating factor for all asthmatics.
