Swedish research few allergies in unstressed babies

If your baby is relaxed and doesn’t show severe signs of stress, you are in for a good news, but if it is restless, it is time for you to fill your medical kit with medicines for allergic diseases. A Swedish research from the Karolinska Institute shows that infants that have a lesser concentration of the stress-related hormone named cortisol in their saliva are exposed to fewer allergies compared with those that are born with a high concentration of the hormone. The scientists involved in the study hope that the results of the study can be used for prevention of allergies in the future.


The incidence of allergies has been noted to have increased over the past few decades in the West. In Sweden, over 30 to 40 percent of children have been found to have some kind of allergy. The doctors and scientists suspect a combination of lifestyle and environmental factors during pregnancy and early infancy to be responsible for the rapid rise in allergic diseases.


Dr Fredrik Stenius of the Department of Clinical Research and Education at Stockholm South General Hospital said that the stress hormone and other psychological factors have link with allergic diseases. The study found out that children who had low salivary cortisol levels as infants had far less scope of getting allergic diseases later compared with those who had a higher level of cortisol.

The team of scientists who worked on the study had revealed the link between the lower prevalence of allergies in school children and anthroposophic lifestyle while the research was on and now they have found the same link in children who belonged to a family that followed an anthroposophic lifestyle. Such children had low cortisol levels.

Researchers deem that factors that are related to stress regulation influence the development of allergies in infants and that they will observe the infants until they flow into childhood.
