According to scientists there is a rise in asthma cases. There has been a 160% raise in cases from 1980 and 1994. When the humidity in a room is raised 10% symptoms are raised by 2.7%. They say that this is because the warmer weather comes more water vapor in the air and more pollen in the air which is triggers for asthma.
Some people say asthma symptoms should get better due to warmer weather which would make flu season shorter. People with asthma tend to have more complications from flues and cold.
