Rise and Work Out!

Individuals with exercise-induced asthma may be less likely to experience an attack in the morning than in the evening, according to the results of a new study.

Researchers conducted exercise tests with 22 people with asthma and 12 healthy patients at 7 a.m. and 6 p.m. and measured the resulting lung spasms.

For individuals with asthma, lung spasm scores were 30 percent higher in the evening as compared to the morning.

While factors such as exercise type, environmental conditions and asthma severity can all affect the occurrence of exercise-induced asthma, researchers believe the time of day may also be an important factor to consider when trying to reduce the likelihood of an attack.
