Did you wash your hands? Did you use all natural soap?
We all are familiar with those questions, but it's for a good reason: Washing with natural soap is essential for preventing the spread of germs that make us sick.
Germs, or microbes, are everywhere. Literally, everywhere. In the air, soil, water and on every surface, including your body. Most microbes are harmless and some are important for human health, like the ones that live in our gut. But there are several germs that cause problems, and these are the ones we prefer not to have on or in our bodies. Our first line of defense against those harmful germs is soap.
Soap doesn't kill germs on our hands, it removes them.
Germs stick to the oils and grease on our hands (sounds yucky, but it's totally normal). Water alone won't remove much of the germs on our hands because water and oil don't like each other, so they won't mix. But soap likes both water and oil. That's because soap molecules are a type of surfactant, which means they have one end that's water loving, or hydrophilic, and one end that's oil loving, or hydrophobic.
When you wash your hands with soap, the soap molecules act as a mediator between the water and oil molecules, and bind with both of them at the same time. Then when you rinse everything off, the soap carries away the germs with the water.
For the most effective hand washing, you must use soap and you must be thorough. Work up a lather because the friction helps lift dirt and oils from your skin, according to the Centers for Disease Control and Prevention (CDC). How long you should scrub depends on how dirty your hands are, but most health authorities recommend at least 20 seconds, or as long as it takes to sing "Happy Birthday" twice. And don't forget to scrape underneath your fingernails. That area is prime real estate for germs.
Once you've washed, be sure to air-dry or towel-dry. There's no agreed-upon best practice for drying, but wet hands are more likely to spread germs than dry ones, the CDC says.
Is antibacterial soap even better? Nope.
Antibacterial soaps have added ingredients like triclosan or triclocarban, which are hydrophobic molecules that can penetrate bacterial cell membranes and kill the bacteria. Sounds impressive, but studies have shown that antibacterial soaps are no more effective than regular soaps at removing bacteria.
In 2016, the FDA issued a rule that antibacterial soaps were no longer allowed to be marketed to the public.
"Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water," Dr. Janet Woodcock, the director of the FDA's Center for Drug Evaluation and Research (CDER), said in a statement. "In fact, some data suggests that antibacterial ingredients may do more harm than good over the long term."
What about hand sanitizer?
The CDC recommends cleaning hands with soap and water, but if that's not an option, then hand sanitizer is a good backup. Studies have found that hand sanitizers with alcohol concentrations of 60-95% are more effective at killing germs than nonalcohol or low-alcohol sanitizers.
The alcohol kills some bacteria and viruses by breaking down their protective membranes, which basically makes them fall apart. But it doesn't work for all germs, such as norovirus, Clostridium difficile, which can cause life-threatening diarrhea, or Cryptosporidium, a parasite that causes a diarrheal disease called cryptosporidiosis, the CDC says. Hand sanitizers also likely don't remove harmful chemicals like pesticides or heavy metals, nor does hand sanitizer work well on super dirty or greasy hands.
Hand washing with soap is, by far, the most effective way to keep harmful germs at bay. SOURCE = LIVE SICENCE
