Caffeine Benefits for Asthma

Caffeine can ease asthma symptoms for up to four hours.

Asthma is chronic lung disease affecting 20 million Americans, including 6 million children. For mild asthma sufferers, short-term relief from mild intermittent symptoms may be as simple as a cup of strong coffee.

Benefits

According to The Cochran Collaboration, caffeine acts as a mild bronchodilator and is chemically similar to theophylline, a drug used to treat asthma. Use of caffeine by study participants resulted in lung function improvements for up to four hours.

Side Effects

Over-consumption of caffeine can cause nervousness, dizziness, increased urination and insomnia; in sensitive individuals, caffeine can raise blood pressure and heart rate. Limit caffeine and cut off consumption early in the day to prevent side effects.

Cautions

Caffeine is not widely considered a suitable alternative to traditional medications for moderate to severe persistent asthma.

Considerations

Theophylline has many of the same side effects as caffeine.

Bottom Line

Seek medical advice before attempting to treat asthma symptoms with caffeine. Do not alter or discontinue medical treatment, especially for moderate to severe asthma, without first consulting a physician.
