German scientists have proved the harm of tattoos on the body of football players.

It should be noted that according to the findings of scientists, the tattoo has a negative impact on the performances of players and on their recovery after receiving any injuries.

Professor Ingo Frobose from the German Sports University of Cologne called on football clubs to forbid their players to make tattoos. The reason for this decision was the ink that enters the bloodstream.

"Various studies have shown that the performance of players after applying the tattoo is reduced by 3-5%. Skin is the largest organ in our body, and we poison it. Further studies have shown that 60-70% of ink from tattoos do not remain on the skin, but fall into the bloodstream. As a result, the ability to recover - and you are not as fresh as before.

"The consequence can be green and blue lymph nodes. In this case, large tattoos can affect the ability of the body to sweat and regulate the temperature, "- said Frobose.
