Asthma symptoms treatment
Ronald Kuppersmith, a clinical assistant professor of family and community medicine at Texas A-M Health Science Center College of Medicine, who was not involved with the research.
'This may provide opportunities to modify the body's response to the rhinovirus and provide opportunities for further research or possibly medication that would significantly reduce the symptoms and maybe even prevent infection in a much more targeted way,' he added.
Human rhinovirus (HRV) causes some 30 percent to 50 percent of common colds and can also worsen more serious conditions, such as asthma.
'Everyone thinks the common cold is fairly innocuous, which it is. But if you have people with lower airway disease -- asthma, bronchitis, emphysema -- these viruses are now known to be very important triggers for people to have acute attacks and that can be life-threatening,' said David Proud of the University of Calgary, the study's lead author and a professor of physiology and biophysics and Canada Research Chair in Inflammatory Airway Diseases
How to tell if smoke is affecting you
Smoke can cause:
- Coughing
- A scratchy throat
- Irritated sinuses
- Shortness of breath
- Chest pain
- Headaches
- Stinging eyes
- A runny nose
- Asthma exacerbations
If you have heart or lung disease, smoke might make your symptoms worse. People who have heart disease might experience:
- Chest pain
- Rapid heartbeat
- Shortness of breath
- Fatigue
Smoke may worsen symptoms for people who have pre-existing respiratory conditions, such asrespiratory allergies, asthma, and chronic obstructive pulmonary disease (COPD), in the following ways:
- Inability to breathe normally
- Cough with or without mucus
- Chest discomfort
- Wheezing and shortness of breath
When smoke levels are high enough, even healthy people may experience some of these symptoms.
Know whether you are at risk
If you have heart or lung disease, such as congestive heart failure, angina, COPD, emphysema, or asthma, you are at higher risk of having health problems than healthy people.Older adults are more likely to be affected by smoke, possibly because they are more likely to have heart or lung diseases than younger people.
Children are more likely to be affected by health threats from smoke because their airways are still developing and because they breathe more air per pound of body weight than adults. Children also are more likely to be active outdoors.
Protect yourself
Limit your exposure to smoke. Following are ways to protect your health:
Pay attention to local air quality reports. Listen and watch for news or health warnings about smoke.
Find out if your community provides reports about the Environmental Protection Agency's Air Quality Index (AQI)
