Neither under the arm, nor in the nostrils, nor in the scalp. The forearm is the skin of our body where more species of bacteria accumulate. The National Human Genome Research Institute of Maryland has reached this conclusion through the skin study of ten volunteers.

Volunteers have taken samples from more than 20 places in the body and differentiated bacterial species by studying ribosomal RNA from bacteria in these samples.

A total of 1,000 species have been found on the skin and, as has been said, have seen that the most bacteria are concentrated in the forearm. The child behind the ear. In addition, it has been observed that in fat parts of the body, such as the forehead, fewer species of bacteria grow than in dry ones.
