The palms are a breeding ground for germs. But what if unexpected ingredients are found? [출처_영국 데일리메일 / 이미지 저작권=코메디닷컴]The palms are a breeding ground for germs. But what if unexpected ingredients are found? Experiments have shown that 1 in 50 people you meet in everyday life may have sperm on their hands.
According to a British Daily Mail report, forensic researchers collected samples from 66 people by scraping (swapping) cotton swabs with samples on their palms. Among the test subjects, 45 were women and 21 were men. As a result of examining the ingredients on the palms, most of them had dirty germs.
Other substances found included hair, dust, and saliva. Hair and dust were detected in a third of participants, and saliva was present in nearly one in 10. Most shockingly, 2% of the people found oval heads of sperm in their hands.
All participants completed a questionnaire recording their age, gender, and when they last washed their hands. In the swap samples, the men did not have sperm on their hands, but sperm was found in two women.
According to the researchers, one of the two women (aged 18 to 29) whose sperm were found had a sperm head on one hand. This participant had washed his hands 1 hour prior to the swap test. Another woman (40 to 49 years old) came out with two other sperm heads. This participant had not washed her hands two to three hours before the swabs were collected. Dust and germs were also detected on the hands of these two samples.
The researchers said they could not confirm whether the sperm heads found in these men were from recent sexual activity or if they were smeared from a contaminated surface. No other tests were added to determine whether it was due to cosmetics, food or dust.
You should wash your hands often to prevent infectious diseases and prevent spreading them to others. [사진=게티이미지뱅크]Spit marks were found on the hands in 9% of the participants, and hair and fibers were still detected in more than a third of those surveyed despite washing their hands within an hour before collection. The amount of hair found on the palms increased by 50% when the hands were not washed for more than 3 hours. Dirt and stains were also found in samples from 40 people, about a third of the participants. Blood tests were also performed, but fortunately there were no traces of blood on any of the hands of the participants.
This experiment was conducted to show the level of bodily fluid present in the hand and the effect of various test methods, and the exact society that conducted the experiment was not disclosed.
The UK’s National Health Service (NHS) recommends frequent hand washing to prevent contagious diseases and prevent spreading them to others. Wash your hands after using the bathroom, changing diapers, before and after preparing raw meat, before and after eating or handling food, after blowing your nose or sneezing, before and after treating wounds or trauma, and after handling pets and animals .
