Humidity can also make asthma symptoms worse in some people, although the reasons why can vary depending on the individual. Here are a few possible explanations:

1. Humidity can increase the amount of mold and other allergens in the air, which can trigger asthma symptoms in people who are sensitive to them.
2. High humidity can cause a person’s airways to become swollen and narrow, making it harder for them to breathe. This is because when the air is moist, it can be more difficult for the body to release heat through sweating, so the body compensates by releasing more fluid into the airways.
3. Humidity can also make it more difficult for a person’s body to regulate their breathing. When the air is hot and humid, people may be more likely to breathe quickly and shallowly, which can cause them to hyperventilate and trigger asthma symptoms.

If you find that humidity is triggering your asthma symptoms, there are a few things you can do to manage them. For example, you may want to avoid spending time outdoors on hot, humid days, or use a dehumidifier to reduce the moisture in your home. You can also talk to your doctor about adjusting your asthma medications or treatment plan to better manage your symptoms.
