The Link Between Asthma and Allergies
People who suffer from asthma are likely to have allergies, too.
A new study followed more than 2.500 adults with asthma.
Depending on their ages, between 65 and 75 percent turned out to have at least one allergy.
Researchers say both asthma and allergies are on the rise and could be related to climate change, hygiene, and increased awareness.
