Study explores why asthma worsens at night

New Delhi, Sep 08 (ANI): For hundreds of years, people have observed that asthma severity often worsens in the nighttime. One longstanding question has been to what degree the body's internal circadian clock -- as opposed to behaviors, such as sleep and physical activities -- contributes to the worsening of asthma severity. Using two circadian protocols, investigators from Brigham and Women's Hospital and Oregon Health & Science University have pinned down the influence of the circadian system, uncovering a key role for the biological clock in asthma. Understanding the mechanisms that influence asthma severity could have important implications for treating asthma.
