2. Weather patterns affect asthma


High temperature Inhaled hot air can narrow the airways. Before going out on the street, you should check the air quality and weather forecast to protect your nose and mouth and take measures to limit going out if the weather is bad. Instead, in hot weather, you should sit in an air-conditioned room and filter out respiratory irritants.
Low temperature When the temperature drops, asthma symptoms may get worse. Cold weather dries out respiratory tissues, making them more sensitive and constricting blood vessels. To reduce the risk of an asthma attack, a scarf can be the solution because they work to warm the air before breathing it into the airways.
Humidity Humid air can also cause respiratory irritation because it is a favorable environment for mold and dirt to grow. To reduce humidity, you should use an air conditioner or dehumidifier. If you need to go outside on a humid day, you should try to get outside in the morning or evening, when the humidity is lower.
High Pollen Concentration Pollen concentration in the air will be higher on windy days. High levels of pollen can cause allergies, which in turn trigger asthma for many people. An allergist can help you find the exact cause. To control asthma caused by pollen allergies, you may be prescribed an allergy nasal spray.

Thunderstorms accompanied by thunder and lightning can threaten people with asthma. That's because rain and thunder hit the pollen, turning them into smaller pieces than usual. Spread by the wind, these pollen particles enter the lungs and cause symptoms. Therefore, if pollen is an asthma trigger, you should not leave the house on rainy days.
Sudden weather changes Sudden weather changes are a condition that triggers an asthma attack. Some experts attribute the cause to changes in atmospheric pressure, while others suggest it is due to changes in humidity and air temperature. You should check the weather forecast to determine the severity of your asthma attack when the weather changes.
Showers can have a two-way effect on asthma. Moderate rain can wash away pollen, reducing the risk of an asthma attack. However, a downpour will break the pollen and carry it everywhere. Dust mites and mold are two other agents that can thrive in wet weather. To improve air quality, you should install air conditioners and make sure humid rooms such as kitchens and bathrooms are well ventilated to prevent mold growth.
Winter Not only asthma, winter is also a favorable time to develop colds and flu. Getting a flu shot will reduce your risk of an asthma attack. You should not use a heater to warm the air, but using electricity or gas in the house will be better for health.

Inhaled corticosteroids such as fluticasone (Flovent Diskus, Flovent HFA) Long-acting beta agonists, such as salmeterol (Serevent) Diskus) Leukotriene receptor blockers, such as montelukast (Singulair) However: Long-acting beta-agonists are always used with inhaled corticosteroids.
A quick-relief is a medicine that you take only when you need it, such as before exercising when it's cold. Short-acting bronchodilators and anticholinergics are examples of these drugs.
