How Long Should You Wash Your Hands? The Definitive Guide to Effective Handwashing


Good hand washing hygiene is a vital aspect of maintaining personal hygiene. It can help prevent the spread of illnesses and infections caused by harmful bacteria and viruses that can live on our hands. In this article, we will explore some essential tips on the ideal length of time you need to wash your hands to ensure complete cleanliness and efficiency.

Official Guidelines for Handwashing

According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), the recommended duration for effective handwashing is at least 20 seconds. This might seem like a long time, but it’s essential to get rid of germs that could make you ill. Handwashing should be longer when hands are visibly dirty.

Studies have shown that washing hands for 20 seconds or more can reduce the number of bacteria and viruses on your hands significantly. It’s also essential to use warm water when washing your hands as it can help break down any oily grime and dirt on the skin’s surface.

Breakdown of Handwashing Steps

The following are the steps for effective handwashing:

  • Wet your hands with clean running water
  • Apply enough soap to cover all surfaces of your hands thoroughly
  • Rub your hands together, including the backs of your hands, between your fingers, and under your nails
  • Scrub for at least 20 seconds
  • Rinse your hands well under clean, running water and air dry or use a clean towel to dry your hands

Each of these steps should take at least five seconds, leading to a total of at least 20 seconds of handwashing for complete effectiveness.

Importance of Soap for Handwashing

If you’re wondering if soap is essential for handwashing, then the answer is yes! Soap helps to remove germs, dirt, and oils from your skin’s surface, so it’s crucial to choose the right type of soap to ensure that you’re cleaning your hands effectively.

Experts recommend using a liquid soap over a bar soap as it’s more hygienic and less likely to harbor germs. It’s also suggested that antibacterial soap might not be any more effective than regular soap, but it is recommended if you’re in a hospital or healthcare setting.

Impact of Germs and Inadequate Handwashing

The importance of handwashing can’t be overstated, especially in public places where you might come into contact with germs and bacteria. Inadequate handwashing can lead to the spread of illnesses like the common cold, flu, or even more severe illnesses.

Without proper handwashing, germs can live on surfaces, such as door handles or countertops, for hours, leading to possible infections spread through touch. Therefore, it’s crucial to take sufficient time to wash your hands thoroughly, even more so in times of illness outbreaks.

Tips for Children

Teaching children the importance of handwashing and how long they need to wash their hands properly is also essential. This can be done by making handwashing a fun activity for them. You can use engaging songs, games, or fun videos to encourage them to wash their hands properly.

It’s also recommended that you supervise young children when they’re washing their hands to ensure they’re washing long enough. Children should also be taught to dry their hands properly after washing them to reduce the risk of any germs sticking around.

Other Effective Methods

If you’re in a situation where you can’t wash your hands, like when you’re out and about, using hand sanitizers is an effective alternative. The alcohol-based sanitizers can kill most of the germs on your hands, but they’re not as effective as soap and water, especially when hands are visible soiled.

When choosing a hand sanitizer, experts recommend choosing one with at least 60 percent alcohol to ensure that it’s effective. It’s also essential to choose the right amount of sanitizer to use for complete effectiveness.


Proper handwashing is essential for good hygiene and can help reduce the spread of germs and illness. In conclusion, washing your hands for a minimum of 20 seconds and following the recommended steps is crucial for thorough cleanliness. Choosing the right soap for handwashing and using hand sanitizers when necessary can also promote good hygiene. Remember to teach young children the importance of handwashing and how to wash their hands effectively for a healthy lifestyle.
