The warning comes from a report in the British Journal of Dermatology that looks at the growing prevalence of such "atopic allergies".
Scientists believe commonly-found airborne chemicals, such as chlorine from pools, as well as compounds found in cleaning products, could be behind the rise in allergies.
During the past 50 years, there has been a five-fold increase in inherited allergies, and researchers believe exposure to the above chemicals could be altering the immune system of children, leaving them more vulnerable to conditions such as asthma, hay fever and eczema.
One theory, known as the "hygiene hypothesis", is that an excessively clean lifestyle has resulted in a generation of children developing immune systems unfamiliar with many germs. As a result, when they are later exposed to new irritants, their body is more likely to have an allergic reaction.
However, experts from the St John's Institute of Dermatology in London and the University of Manchester are investigating whether exposure to everyday airborne chemicals "during critical windows of pregnancy/early-life development" have also contributed to the increased number of cases.
The report states: "High-level exposure to volatile organic compounds in the domestic environment either during maternal pregnancy or in early life, is associated with development of childhood atopic disease.
"Similarly, sustained exposure to airborne chlorinated chemicals from swimming pools during childhood has been associated with the development of atopic allergy."
Dr John McFadden, consultant dermatologist at St John's Institute, said further investigation was needed.
"We in the science world are still struggling to find the exact cause of this rise. We have not proved anything, we are not saying this is the cause, this is a hypothesis, but we do know we are using far more chemicals than we did 50 years ago, whether it is in personal care products or processed food.
"It is conceivable, but not proven, that persistent low-dose exposure to chemicals can have some effect on the immune system."
He added that the findings of the report should not alter the advice currently given to mums-to-be, but did say the link needed to be studied further.
Currently, expectant mothers are encouraged to continue exercising throughout their pregnancy, with the NHS recommending swimming as an activity because the water helps support their additional weight.

New Warning For Women Who Swim During Pregnancy
