Everyone knows that before eating, after the street and especially after staying in public places, you need to wash your hands thoroughly, because there are many diseases, popularly known as "diseases of dirty hands", which are very easy to avoid if you follow this advice familiar to everyone from childhood. Interestingly, the dirt in the village, in the country, in the forest is not so dangerous as in large cities, where luxurious conditions for living and reproduction are created for pathogens in public transport, shops, restaurants, schools and hospitals - everywhere during the day there are large flows of people.
An interesting study by American microbiologists who analyzed and ranked the dirtiest places in the office. The leaders, which means the most dangerous foci of infections, are sinks and faucet handles in toilets, followed by the handles of microwave ovens and refrigerators and, of course, closes the top three - computer keyboards and mice. The list of the dirtiest and most dangerous also includes refrigerator handles and buttons for coffee machines.
Hotels and hotels also have their own dirtiest places. It is interesting and unexpected that in the first places are the TV remote control, telephone buttons and lamp switch. However, these items are significantly inferior to the bucket, mop and gloves of the maid, who not only cleans the room, but also transfers bacteria from one room to another.
However, no one is immune from bacteria and microorganisms in their own home. Interestingly, the dirtiest place in our house is not the toilet, but a wooden cutting board. Based on the results of research by some scientists, it is home to 200 times more germs than a toilet. The second most popular among microbes is the home telephone, or rather the handset. The dirtiest ranking also includes -
dishwashing sponge, shower curtain and kitchen trash can. You should also not forget about the dishwasher and washing machine, on the doors of which mold and mildew may form.
Taking into account all of the above, human palms can also be called dirty places and this can be proved by a study conducted by American scientists who took samples from the palms of 51 students (102 hands) and found more than 4.5 thousand species of bacteria, which roughly means 150 species on each hand and only 5 of them were found on each palm.
