Where is the dirtiest part of the human body

The human body is made up of many parts. Although some people usually like to be clean, in the eyes of many people, there are many dirtiest parts of the body, such as feet, buttocks, etc. In fact, the dirtiest parts of the human body are not only these parts. Some dirty parts may have a lot of bacteria, but we mistakenly think that they are relatively clean places. The following is a detailed introduction to the dirtiest parts of the human body.

What is the dirtiest part of the human body?

The dirtiest part of the human body is actually the hands. Many people have no accurate understanding or concept of how dirty the hands are. However, according to expert research, human hands are dirtier than any other part of the body. There are up to 800,000 bacteria on a pair of unwashed hands, and 3.8 billion bacteria are hidden in one gram of nail dirt, which is even dirtier than the toilet at home. So if you put your fingers in your mouth, the consequences can be imagined. If you are not careful, it will cause many diseases and will definitely cause great harm to your health.

Therefore, never put your hands in your mouth, watch your children and don't let them suck their fingers. In daily life, we should wash our hands frequently. It is best to use some sterilized soap or hand sanitizer and wash them repeatedly. If conditions permit, we can trim our nails at least once a week, preferably once or twice. This can greatly reduce the number of bacteria on our hands.

People must understand every part of their body to protect their healthy life and not cause physical harm due to blind spots in some health aspects. You can learn more about health and wellness in your daily life, not only for yourself, but also for your family and friends, so as to get out of health misunderstandings.

Which parts of a woman's body are the dirtiest?

1. Scalp

The scalp is the home of hair follicle sebaceous mites. Studies have found that there are about 1 million microorganisms per square centimeter of the scalp, the most numerous of which are hair follicle sebaceous mites. They like to make their home in the epidermis of the scalp, combining in groups of three or five to form a "big family", working together to survive by sucking the lipids secreted by the sebaceous glands, and the ultimate result is hair loss.

If you want to fight them, in addition to washing your hair frequently, it is best to comb your hair with a comb every morning and evening to stimulate the scalp and allow it to ventilate.

2. Nose

Although it is in the middle of the face, it is in the "shadow" of the nose. When looking in the mirror, you often see that the areas where the sides of your nose meet your nasolabial folds are red or dark. This is because external pollutants and dead skin easily accumulate in this area.

Therefore, the nose should be exfoliated regularly and the mask should be applied a little thicker in this area.

3. Behind the ears

It is used when doing cosmetic allergy testing, it is massaged when unblocking the lymphatic system... This area behind the ear has many uses, but receives little attention. Especially during daily cleaning and maintenance, we rarely think about it.

When washing your face and taking a shower, you should also clean behind your ears, as this is an area that many people tend to overlook.

4. Oral cavity

The mouth is a place where food must pass through, but did you know that there are more than 100 million microorganisms per square centimeter in our mouth, including good bacteria and a considerable number of bad microorganisms, which are the culprits of bad breath.

They live between teeth and on the tongue, producing foul-smelling sulfur compounds as they break down food particles and saliva. Keep your oral cavity clean and hygienic, brush your teeth carefully in the morning and evening, remember to use dental floss to clean between your teeth before brushing, and clean your tongue after brushing your teeth. The bacteria remaining on the tongue will also damage your breath.
