Our immune system has the task of protecting us against bacteria and viruses. Our bodies are also equipped to handle everyday stress–that is, stress that lasts only briefly.
On the other hand, a difficult, stressful situation or long-term increase in stress can negatively affect the immune system. This kind of long-term stress can develop when a close family member dies or when adults are caught in tough, unmanageable situations.
The research study shows that children in highly-stressed families had a high level of cortisol, which is a biological marker of stress. This supports the idea that the children were stressed. The research study also points towards the fact that a high level of stress negatively affects the immune system–that is, it is not as resistant when the body is exposed to a high level of stress. Instead, the immune system reacts to substances in the body that should be left alone, which perhaps is linked to an autoimmune reaction.
The study included families with five-year-old children (derived from the ABIS [All Children in Southeast Sweden] study). The parents answered questions regarding stress and prospective difficulties that had impacted the family, such as divorce or unemployment.
The answers led the researchers to identify a group of children who probably experienced high levels of stress in their families, and a group of children who presumably had grown up with normal stress levels.
The research group at the School of Health Sciences in Jönköping will work further on the project to understand more about how a high level of stress can affect the body. This time, the researchers will turn to young people in the 18-22 age group.
“These young people can themselves report negative experiences in their daily lives and also negative experiences during their childhood” says Maria Faresjö, professor at the School of Health Sciences, which will also lead the continued research project.
The article, “Psychological stress in children may alter the immune response”, is being published in Journal of Immunology (2014, DOI: 10.4049/jimmunol.1301713).

Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.
By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...
Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne Leadership Computing Facility (ALCF) researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.
While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been...
