Heat Wave Increases Allergy, Asthma Symptoms
This week I noted my patients are complaining about an increase in their asthma or allergy symptoms due to the heat wave that is blanketing much of New York City and the rest of the Northeast.
A lot of this is due, as the CDC (Centers for Disease Control) reports to an increase in carbon dioxide (CO 2) concentrations. It states that "earlier flower blooming resulting from temperature increases and increased carbon dioxide (CO 2) concentrations affects timing of distribution of aeroallergens such as pollen through plant photosynthesis and metabolism. Certain aeroallergens may become more allergenic as temperatures and CO 2 concentrations increase. Air pollution overcomes the mucosal barrier in lungs by inducing airway inflammation, which results in allergen-induced respiratory responses."
When people are walking around outdoors, especially in Manhattan, vehicle exhausts, also can increase the ozone level adding complications to those who already have respiratory problems.
To help limit respiratory problems in the heat, I suggest doing the following:
- Wear a hat and loose fitting cotton clothing;
- Carry all your asthma and allergy medications;
- If feeling dehydrated, duck into an air-conditioned building and stay there for a while;
- Change your home air conditioner filter frequently. Indoor pollutants can affect your breathing, so it's important to keep you filter clean.
- Drink lots of water, hydration is very important. especially before going outdoors (this will help clear your sinuses and prevent excessive perspiration, which can complicate your lung function. Once outdoors, carry water with you and drink frequently. Even in the subway, temperature there can even exceed temperatures on the street.
