Over 400 types of bacteria reside in the intestines. Intestinal Escherichia coli (E. coli) acts as a beneficial tenant in the human body, aiding digestion and serving as part of our defense system. However, E. coli outside the intestines can cause illness. If it contaminates food, it may lead to nausea, vomiting, and diarrhea.To protect your gut, consider drinking 1–2 bottles of yogurt daily. The probiotics in yogurt suppress harmful bacteria from dominating the gut, helping beneficial bacteria gain control. Additionally, maintaining moderate exercise—such as doing push-ups and abdominal massages—can prevent intestinal aging.
Underarms On crowded buses or subways, you've likely encountered that unbearable odor more than once! It emanates from underarms, unabashedly polluting the surrounding air.Microbes lurking in the armpits number as high as 1 to 10 billion per square centimeter. Sweat itself is odorless, but armpit "regulars" like bacilli thrive on fatty acids secreted by the skin, multiplying rapidly and producing unpleasant odors. Armpit sweating isn't a disease—it can be eliminated by showering frequently and changing clothes often. Cotton undergarments are the best choice.
The Mouth The mouth is the gateway for food, but did you know it hosts over 100 million microorganisms per square centimeter? While some are beneficial bacteria, a significant portion are harmful microbes—the primary culprits behind bad breath. These microorganisms reside between teeth and on the tongue, breaking down food particles and saliva while producing foul-smelling sulfur compounds.Maintain oral hygiene by thoroughly brushing your teeth morning and night. Remember to floss before brushing to clean between teeth, and scrape your tongue afterward—bacteria lingering on the tongue can also cause bad breath.
Scalp research reveals approximately one million microorganisms per square centimeter of scalp, predominantly Demodex folliculorum mites. These mites prefer to reside within the epidermal layer of the scalp, clustering together in groups to form "extended families." They collectively subsist by feeding on lipids secreted by sebaceous glands, ultimately contributing to hair loss.To combat them, in addition to frequent shampooing, it's best to comb your hair morning and night. This stimulates the scalp and promotes ventilation. Surprised by what you've read? For your health, make sure to clean these areas more thoroughly.
