What COPD Does to Your Heart

People with COPD are two to three times more likely to develop cardiovascular disease than those without it.
Autumn leaves

Chronic obstructive pulmonary disorder (COPD) knows no season. Weather changes can cause a COPD exacerbation, or flare-up, at any time of year. Common symptoms include increased difficulty breathing, a tightening of the chest, increased coughing or wheezing, increased mucus production and even confusion and forgetfulness. And if the symptoms aren’t addressed, they could mean a trip to the emergency room. So, rain or shine, snow or sun, people with COPD have to be vigilant about the weather’s potential effect on their health.


When the trees start budding and the flowers start blooming, it’s time to prepare for spring—spring allergy season, that is. Not everyone with COPD suffers from common spring allergies, but research shows that COPD patients with allergies are at higher risk for COPD flare-ups. If you’re one of them, be sure to check the pollen count at the National Allergy Bureau website before venturing outside. If the pollen counts look high, plan to stay inside as much as possible.

Another problem with springtime—the  weather can vary widely in the course of just a few hours. And the big swings in temperature and weather can trigger COPD exacer bations or make symptoms worse.


The heat and humidity that are often the hallmarks of summer can trigger COPD flare-ups. Your body has to work harder to breathe and stay cool when it’s hot, which can cause exhaustion, and higher humidity levels make the air heavier so it’s more difficult to breathe. Smog levels tend to be higher on hot, humid days, which can also trigger flare-ups. You can monitor the smog levels in your community to help you decide if it’s worth it t o go outside. Wildfires are more common in summer and can spread smoke for long distances. Smoke from wildfires can be quite hazardous for individuals with COPD or other respiratory problems.


Autumn brings cooler weather, which relieves some COPD symptoms; however, you’ ll still want to monitor air quality, as this season has its own set of allergens. Ragweed is the worst offender, according to the American College of Allergy, Asthma & Immunology. You might develop symptoms like a runny nose, sneezing, and an itchy throat, but you may also experience asthma-like symptoms of coughing and wheezing, which may be much worse  due to your COPD. Keep your windows and doors shut if you’re afflicted with allergies to  autumn pollen. You might also want to stay inside during the middle of the day when pollen counts are highest.
