Expose which dirty things you must never do

Barefoot fitness:

The survey found that 32% of people exercise barefoot, especially when doing aerobics or belly dancing. Experts suggest that it is best to wear a pair of light shoes at this time. Because your feet will sweat a lot when you exercise, the humid environment is most conducive to the growth of bacteria. These bacteria will be left on the floor by other people's feet. When you step on them, you may be infected with athlete's foot or plantar warts.

Not brushing teeth before going to bed:

43% of people admitted that they occasionally forget to brush their teeth before going to bed. Experts warn that the amount of saliva secretion will be greatly reduced during sleep, and this saliva is the main force in killing bacteria. Therefore, if you fail to brush your teeth occasionally, oral bacteria may take advantage of the opportunity to enter, resulting in a greatly increased risk of caries and periodontal disease. Additionally, many studies have shown that the same bacteria that cause periodontal disease can also cause problems for your heart.

Taking a bath without using bath gel:

The survey shows that nearly 1/3 of women do not use bath gel when taking a bath every day, but just rinse with water. Experts point out that whether to use bath gel when taking a bath should be determined based on your sweating condition. The bacteria that cause body odor feed on sweat, especially sweat from the armpits and groin. When you sweat a lot, just washing with water will not wash it away completely, as it will cause bacteria to remain. The longer the bacteria remain, the "smellier" you will be.

Washing hands without soap after using the toilet:

In the survey, only 38% of people washed their hands with soap after using the toilet, and 2% washed their hands for more than 10 seconds. Experts say that when you wipe your hands after using the toilet, your hands are very close to the source of E. coli, which may cause bacterial infection. If you don't use soap, you can't completely eliminate the bacteria.

Underwear is not changed every day:

In the survey, 52% of women admitted that they did not change their underwear every day. Microbiologist Dr. Charles Gerba pointed out that if underwear is worn for one day, about 0.1 grams of excrement will remain on it, which is roughly equivalent to 100 million E. coli. These bacteria will attach to your hands, and if you rub your eyes or even eat without washing your hands, you will get sick.

Pick up the food you dropped and eat it again:

More than 40% of women said they had eaten food that had just been dropped on the ground and then picked up. There used to be a saying called the "5-second rule", which means that as long as the fallen food is picked up and eaten within 5 seconds, it is safe. Researchers point out that this statement can be extremely misleading. Experiments have shown that food can be contaminated by bacteria in just two or three seconds after it falls to the ground. Therefore, any food that falls on the ground should be thrown into the trash immediately.
