Your body does not wait for the disease to prepare to prepare for combat. Consequently, Simply in contact with sick people can activate your immune system. However, even if these people are not real, according to a new study.
A team of Swiss researchers used virtual reality (RV) in a study published in the journal Nature Neuroscience. Consequently, in order to test the biological reactions of people in the face of potential health threats. Moreover, According to them, RV could be a promising complement to other tools to strengthen the immune system, such as vaccines.
During the experience. Meanwhile, the researchers connected 248 young people in good health to machines who measure brain activity, then they put on RV headsets that brought them to a virtual world populated by sick people. Therefore, Some of the avatars had visible infections, such as rashes or coughs, while others virtual reality could lead our looked frightened or had neutral expressions.
When the sick avatars approached very close to the participants. However, their brain illuminated in a different way from that observed when approaching neutral or frightening faces. More specifically. the avatars have activated what is called the salience network, that is to say the parts of the brain which mainly detect “salient stimuli, including threats”, according to the study.
The blood samples of people exposed to sick avatars have also shown a peak in activity of innate lymphoid cells. which constitute a key element of the immune response. These cells are activated by pathogenic threats, which allows the body to react quickly.
The body reacts in the same way to a real infection, such as a flu vaccine.
“We thought that [les réactions seraient] very light. “said Euronews Health Dr Camilla Jandus, one of the study authors and immunologist at the University of Geneva.
“We really didn’t expect to virtual reality could lead our see cell changes in the space of a few hours.”
These results suggest that our brain can detect the potential threats of infections even before we are in contact with a sick person. which puts our immune system in defensive mode, the researchers said.
“When the infectious threat enters our body, the immune system reacts, but it is often too late,” said Ms. Jandus. “We consider this detection of something virtual as an alert system that could trigger, early, your immune system.”
Researchers do not know exactly how the brain. the immune system work together to fight pathogens, or if the immune response triggered by RV would be as robust and durable as that caused by a vaccine.

But their conclusions seem to be part of the line of previous research suggesting that the body acts as. a “smoke detector” which reacts to potential health threats which prove to be false alarms. Anxiety, virtual reality could lead our inflammation, pain, vomiting, cough and diarrhea can be protection reactions.
The study is one of the first of its kind. so that researchers working on larger groups would be necessary to confirm the results.
The Jandus team is trying to find out if the immune system of people reacts differently to RV scenarios presenting the threat of bacteria. viruses.
It also wishes to study whether RV environments can help strengthen the immune response to vaccines. if these environments can serve as exposure therapy for people with allergies.
In this way. when people are really infected with an allergen or a virus, “you have already anticipated and prepared your body to react, with the hope of having a better answer,” said Dr. Jandus.
