Scientists have found high internal temperatures seem to worsen chronic obstructive pulmonary disease, or COPD
condition is a general term for chronic bronchitis, emphysema and other diseases, many of which are incurable, but can be alleviated with treatment.
researchers said that “optimizing indoor climate ‘could improve the health of millions of people suffering.
COPD affects about three million Britons, but it is estimated that there are around . 80,000 diagnosed cases of lung cancer and one million cases of COPD
professor Meredith McCormack: “previous studies have found that the elderly are especially vulnerable to the effects of heat and more likely to die or be hospitalized for heat waves
“Our study is based on these research findings exposure to individual level -. including in-home assessment of temperature and specific health effects of COPD.
“to our knowledge this is the first study reporting an interactive effect between the internal temperature and indoor air pollution in COPD.”
scientists focused in 69 patients with moderate to severe COPD during the hottest days of the year in the US city of Baltimore.
participants completed a daily questionnaire that included dyspnea, cough, and sputum Scale (BCSS).
was also measured lung capacity of patients
researchers compared the results with measurements of the temperature outside and two indoor air pollutants -. PM2.5, fine particles, and NO2, nitrogen dioxide.
generally found that participants spent the vast majority of their time indoors, but in the days that the average duration was extinguished about two hours.
experts found the found scores BCSS worsened with increased indoor temperature and the use of rescue inhalers also increased
The effect of higher indoor temperatures – ., who they lived immediately and continue for up to two days – was also magnified by high levels of PM2.5 and NO2.
However experts said that the lung function itself was not affected by rising temperatures or higher levels of indoor air pollutants.
Dr. McCormack, of Johns Hopkins University in Baltimore, health professionals could protect the most vulnerable to heat.
“participants who received spent an overwhelming majority of their time indoors, which we believe is representative of patients with COPD in general, optimizing indoor climate and reducingindoor pollution poses a potential avenue to improve results health, “he said.
The study was published in the journal Annals of the American Thoracic Society.
