Effects of air temperature on asthma
Asthma is a medical condition that directly affects the airways. The air you breathe in can affect your asthma symptoms. In most cases, these symptoms are usually determined by different aspects of the air, such as humidity and temperature [4]. Asthma triggers commonly occur due to changes in air temperature. For example, a sudden increase or decrease in temperature as you enter a building may cause symptom triggers. High humidity and extreme air temperature in both outdoors and indoors may exacerbate your symptoms.
Heat
When the environment is hot and humid, you may find it difficult to breathe because inhaling this type of air can be irritating to your airways. Hot weather may also make you breathe faster and become dehydrated causing asthma flares. In hot temperatures, air pollution and pollen counts are high. Pollution and Pollen can trigger asthma symptoms [5].
Cold
Extreme cold environments can also exacerbate asthma symptoms. In most cases, cold air is usually dry and it causes the mucus covering your airways [6] to evaporate. This may cause irritation in your airways.
