Some doctors are now linking a risk of developing allergies to your birthdate.
Researchers at the University of Southampton in England looked at the genetics of babies born in different seasons and concluded those born in the fall and the winter have a higher risk of developing chronic allergies and even more serious conditions.
It's not just allergies though. Researchers also found that people born in autumn, for example, have an increased risk of developing eczema compared to those born in the springtime.
More than thirty percent of adults and 40 percent of children live with allergies, according to the Asthma and Allergy Foundation of America.
The doctors say more research needs to be done and conditions differ case by case.
