Body odor changes when near sick people

Changing the body odor when you're near sick people is a way for the body to warn about the spread of illness.

A recent study by American scientists showed that when healthy mice were kept in cages with sick animals, their body odor changed and became like the smell of sick mice.

In this study, some mice were injected with E. coli bacteria. Later, they were kept in a stable with healthy rats.

Just hours later, mice injected with the drug showed symptoms such as fatigue or weight loss but did not infect other healthy mice.

Then, a group of specially trained smells of rats were released into the barn, they found that the urine of the infected mice was similar to that of healthy mice by 90%.

Scientists analyzed urine composition in these mice. Results showed that 75% of healthy mice had chemical composition in urine similar to sick children.

This indicates that the odor and chemical components in the urine change when healthy mice are exposed to sick children.

"Exposure to the body odor of sick individuals can cause a protective reaction or preparation in their other counterparts to minimize the risk of infection ," said Dr. Stephanie Gervasi, research director. said.

According to the researchers, this mechanism is thought to be an evolution in animals that live in colonies to warn other children about the spread of disease.

'Research shows that body odor not only signals disease, but also has a strong effect on individuals who discover them. This is the olfactory transmission of information that changes the physiological function clearly and can play an important role in the transmission of disease among individuals in many species, ' said Dr. Gary Beauchamp, another author. of research, said.

The team hopes this finding could contribute to the detection and diagnosis of diseases in both humans and animals.
