Climate Change Could Be Tough on Seniors' Health: Study

Wide temperature swings in summer could lead to 10,000 excess deaths in U.S. per year

MONDAY, April 9 (HealthDay News) -- Even small swings in temperatures could put elderly people with chronic illnesses such as diabetes, heart failure and lung disease at greater risk of death throughout the coming summer, a new study indicates.

Researchers from the Harvard School of Public Health in Boston found temperature fluctuations related to climate change could claim thousands of lives every year.

Experts predict climate change could increase variations in summer temperatures, particularly in the mid-Atlantic states and in parts of France, Spain and Italy. In these more volatile regions, this could pose a serious public health risk, the study authors claimed.

Indoor Air Quality and Pollution Awareness


Modern bedroom

Many Americans are aware of the dangers of poor air quality from pollution in the outside world. Pollen counts and air quality index readings are reported alongside the temperature and humidity in daily weather forecasts. Warning labels and news stories have long alerted Americans to hazards found in tap water, consumer goods, and food products, some of the common means of ingesting potentially harmful biological and chemical compounds. However, surveys indicate that the general public does not share the same level of awareness with indoor air quality (IAQ). Although many Americans may feel as though the air they breathe when they are indoors is cleaner and safer than the air they breathe outside, research suggests that, in reality, the exact opposite is true. Generally speaking, indoor air contains much higher levels of toxins and Volatile Organic Compounds (VOCs). Chemicals from building products, harmful levels of mold, dust mites, indoor allergens, and other indoor pollutants all contribute to poor IAQ. Polluted indoor air is becoming increasingly damaging to the health of Americans, despite their unfamiliarity with the issue.

COPD Myths and Truths


COPD is often misunderstood because symptoms can be caused by three different diseases. Separating fact from fiction will help you live better and better manage COPD.


Medically reviewed by Lindsey Marcellin, MD, MPH


Chronic obstructive pulmonary disease (COPD) can be confusing because it isn’t a single condition — it actually refers to a group of lung diseases that makes it difficult to breathe.
Truths and myths about COPD
"COPD is an umbrella term for three different diseases," says Timothy R. Wu, MD, director of the COPD Center at Lahey Clinic in Burlington, Mass. Emphysema, chronic bronchitis, and chronic asthmatic bronchitis can all cause COPD symptoms. What these diseases have in common is obstructed air flow through the lungs.
Common misunderstandings about COPD include that it only occurs in older smokers and that nothing can be done about it. However, that’s not necessarily the case. To better understand COPD and how to live with it, start by learning how to separate the myths from the facts.
Myth or Truth: Only Smokers Get COPD
COPD symptoms such as cough, shortness of breath, and frequent lung infections are among the most common symptoms experienced by long-term smokers. While emphysema, chronic bronchitis, and asthmatic bronchitis are usually caused by smoking, there are other causes as well. "Smoking is almost always the cause of COPD in the United States, but in many parts of the world, COPD may be more commonly caused by wood smoke from cooking fires," says Dr. Wu. Other non-smoking causes include:
  • Some progressive forms of asthma
  • Being born without a protein called alpha-1 antitrypsin
  • Workplace exposures to gases and fumes
  • Heavy exposure to secondhand smoke or air pollution
Myth or Truth: COPD Only Occurs in Older People
COPD is more common in older people who have smoked for many years, but a simple test called spirometry may detect early changes from COPD in younger people. Spirometry is a lung function test that involves blowing into a small machine that measures lung capacity. This test can be read immediately, and it is a reliable way to make a diagnosis.
"Even before COPD symptoms develop, the early changes of emphysema or bronchitis may be present," says Wu. "If younger smokers are screened with spirometry, COPD may be diagnosed in people as young as 30 or 40."
Myth or Truth: People With COPD Need to Slow Down
COPD symptoms may make some types of activity difficult, but slowing down is not good for those with COPD. Physical therapy, including breathing exercises and exercises to strengthen the arms and shoulders, can be an important part of treatment. Regular exercise along with a healthy diet helps muscles stay strong, and that reduces the demand placed on the lungs.
People with COPD should also try to stay active socially. Isolating yourself at home can lead to depression, which can make symptoms worse. It is important to stay in touch with friends and family and maintain a good support network. Many people with COPD also benefit from participating in support groups.
Myth or Truth: There Is No Treatment for COPD
The biggest myth about COPD is that you can't do anything about it. Although there is no cure for COPD, it can be treated and managed in many people. "How well COPD can be treated depends on how advanced it is and what other diseases may be present, such as hypertension and heart disease," says Wu. You can slow down the progression of COPD by:
  • Taking medication as directed
  • Getting pulmonary rehabilitation
  • Using oxygen as needed
  • Stopping smoking
With these changes, many people are able to manage their COPD symptoms well. If you smoke, even if you are still in your 30s, ask your doctor to check your lung capacity. Many of the irreversible effects of chronic bronchitis, emphysema, and chronic asthmatic bronchitis can be avoided with early diagnosis and treatment.
"It is never too late to stop smoking. As soon as you quit, your lung function starts to improve," says Wu, although lung function will never get back to normal once COPD starts. COPD symptoms develop over time, and changes in your lungs may have already started without you knowing it. The best time to stop smoking is right now.
