Most of the 24 million Americans with asthma and other chronic respiratory diseases rely on inhalers.
No wonder almost 800 Million inhalers are manufactured in America every year.
In this context certain interesting studies were done on alternative therapy for asthma.
Several such studies were done on the effect of caffeine in asthma.
The caffeine in the form two cups of strong coffee works very much like any common prescription drug in relieving asthma, and the brew may serve as an effective substitute in an emergency, a study concludes.
Researchers however cautioned that coffee should not replace asthma medicine in routine treatment, but they said it can help in a pinch when the medicines are not available.
The power of coffee to relieve asthma was first reported 125 years ago.
Caffeine may have some benefits for asthmatics.
They apparently can breathe much more easily after consuming a few of cups of coffee, a team of scientists report.
But researchers say asthmatics should not avoid conventional medical care while taking a big gulp of coffee and deep breath of fresh air.
The latest coffee study, conducted by researchers shows that caffeine consumption equivalent to three cups of coffee per day surprisingly improved lung function for a group of adult asthmatics.
Coffee consumption, which has been blamed for many ill effects on health, may actually have a health benefit when it comes to asthma.
In another large-scale study in Italy, bronchial asthma was less common among coffee drinkers than among non-drinkers.
The study indicated that, at least with moderate use, the benefit increased with the amount of coffee consumed.
Prevalence of asthma was lower among people who drank three or more cups a day than among two-cup consumers, and lower.
