An easy way to prevent infection
Hand washing is a simple habit, something most people do without thinking. Yet hand washing, when done properly, is one of the best ways to avoid getting sick. This simple habit requires only soap and warm water or an alcohol-based hand sanitizer — a cleanser that doesn't require water. Do you know the benefits of good hand hygiene and when and how to wash your hands properly?
The dangers of not washing your hands
Despite the proven health benefits of hand washing, many people don't practice this habit as often as they should — even after using the toilet. Throughout the day you accumulate germs on your hands from a variety of sources, such as direct contact with people, contaminated surfaces, foods, even animals and animal waste. If you don't wash your hands frequently enough, you can infect yourself with these germs by touching your eyes, nose or mouth. And you can spread these germs to others by touching them or by touching surfaces that they also touch, such as doorknobs.
Infectious diseases that are commonly spread through hand-to-hand contact include the common cold, flu and several gastrointestinal disorders, such as infectious diarrhea. While most people will get over a cold, the flu can be much more serious. Some people with the flu, particularly older adults and people with chronic medical problems, can develop pneumonia. The combination of the flu and pneumonia, in fact, is the eighth-leading cause of death among Americans.
Inadequate hand hygiene also contributes to food-related illnesses, such as salmonella and E. coli infection. According to the Centers for Disease Control and Prevention (CDC), as many as 76 million Americans get a food-borne illness each year. Of these, about 5,000 die as a result of their illness. Others experience the annoying signs and symptoms of nausea, vomiting and diarrhea.
Proper hand-washing techniques
Good hand-washing techniques include washing your hands with soap and water or using an alcohol-based hand sanitizer. Antimicrobial wipes or towel are just as effective as soap and water in cleaning your hands but aren't as good as alcohol-based sanitizers.
Antibacterial soaps have become increasingly popular in recent years. However, these soaps are no more effective at killing germs than is regular soap. Using antibacterial soaps may lead to the development of bacteria that are resistant to the products' antimicrobial agents — making it even harder to kill these germs in the future. In general, regular soap is fine. The combination of scrubbing your hands with soap — antibacterial or not — and rinsing them with water loosens and removes bacteria from your hands.
Proper hand washing with soap and water
Proper use of an alcohol-based hand sanitizer
Alcohol-based hand sanitizers — which don't require water — are an excellent alternative to hand wash, particularly when soap and water aren't available. They're actually more effective than soap and water in killing bacteria and viruses that cause disease. Commercially prepared hand sanitizers contain ingredients that help prevent skin dryness. Using these products can result in less skin dryness and irritation than hand washing.
Not all hand sanitizers are created equal, though. Some "waterless" hand sanitizers don't contain alcohol. Use only the alcohol-based products. The CDC recommends choosing products that contain at least 60 percent alcohol.
To use an alcohol-based hand sanitizer:
If your hands are visibly dirty, however, wash with soap and water, if available, rather than a sanitizer.
When should you wash your hands?
Although it's impossible to keep your bare hands germ-free, there are times when it's critical to wash your hands to limit the transfer of bacteria, viruses and other microbes.

Kids need clean hands, too
You can help your children avoid getting sick by insisting that they wash their hands properly and frequently. To get kids into the habit, teach by example. Wash your hands with your children and supervise their hand washing. Place hand-washing reminders at children's eye level, such as a chart by the bathroom sink for children to mark every time they wash their hands. Make sure the sink is low enough for children to use, or that it has a stool underneath so that children can reach it. Tell your children to wash their hands for as long as it takes them to sing their ABCs, "Row, Row, Row Your Boat" or the "Happy Birthday" song. This works especially well with younger children, who may rush when washing their hands.
Older children and adolescents also can use alcohol-based hand sanitizers. Younger children can use them, too — with an adult's help. Just make sure the sanitizer has completely dried before your child touches anything. This will avoid ingestion of alcohol from hand-to-mouth contact. Store the container safely away after use.
Hand washing is especially important for children who attend child care. Children younger than 3 years in child care are at greater risk of respiratory and gastrointestinal diseases, which can easily spread to family members and others in the community.
To protect your child's health, be sure your child care provider promotes sound hygiene, including frequent hand washing or use of alcohol-based hand sanitizers. Ask whether the children are required to wash their hands several times a day — not just before meals. Note, too, whether diapering areas are cleaned after each use and whether eating and diapering areas are well separated.
A simple way to stay healthy
Hand washing doesn't take much time or effort, but it offers great rewards in terms of preventing illness. Adopting this simple habit can play a major role in protecting your health.
