Map reveals the location of bacteria and chemicals on the human body

Through this 3D topographic map, experts have discovered areas of high concentration of dangerous bacteria for humans.

Map of bacteria on human body

Skin is the largest and most exposed organ of the human body . Not only are they covered all over the body but they also "carry" on them billions of bacteria and viruses from the chemicals we touch every day.

Red spots are the place with the highest concentration of different bacteria or chemicals, the blue part is the location with less bacteria.

Recently, experts have mapped "terrain " on the skin to find out exactly what exists on the skin and better understand the interaction between skin cells, bacteria, residual chemicals. .

To create these maps, the researchers asked a man and a woman not to bathe, shampoo and use most of the commonly used cosmetics for three days.

In this picture, you can see the high concentration of sodium lauryl ether sulfate on the head - chemicals in shampoo or avobenzone - chemicals in sunscreens even though you haven't washed your hair or applied sunscreen 3 days .

After three days, they will be taken 400 samples throughout the skin on the body and taken for analysis. The results showed that cosmetic products were applied to our skin, like soap and shampoo, which seemed to leave a chemical residue on the skin all day, week or longer.

The image shows the diversity of bacteria found on different parts of the skin for men and women studied.

The images below show the diversity of bacteria and the residual chemical flow on the skin of both subjects. Red spots are the place with the highest concentration of different bacteria or chemicals, the blue part is the location with less bacteria.

Besides, in-depth study, experts also discovered dangerous bacteria such as self-infection on the skin - one of the bacteria that can cause serious infections - is found in wet body parts. like legs, under the breasts of women or on the nose of men.

Experts say that this map not only helps you better understand the impact of the bacterial community on the skin over time, but also makes you notice "cleaning" the areas where many dangerous bacteria are concentrated.
