Proper hand hygiene: The facts

Handwashing is and remains one of the most important means of breaking chains of infection. However, washing them too often can also dry them out. Check the following overview of the most important situations to wash your hands:

It’s best to wash your hands after:

• returning home
• using the toilet
• blowing your nose, coughing, or sneezing
• contact with waste
• contact with animals or animal food

It’s best to wash your hands before:

• eating
• putting on make-up and lotion

It’s best to wash your hands both before and after:

• cooking and preparing food
• contact with sick people
• treating wounds

How you wash your hands is also crucial. Here, we summarize the most important handwashing steps:

1. Moisten your hands with water. Water that’s too hot can irritate and dry out your skin and should therefore be lukewarm at most.
2. Lather your hands thoroughly. This includes the palms, backs of the hands, fingertips, and spaces between the fingers. Don't forget your fingernails and nail folds, either. Press your fingers together, including your thumbs, and move your fingertips back and forth in the middle of the other palm.
3. Thorough handwashing takes 20 to 30 seconds. So rub all areas of your hands thoroughly for this time.
4. Afterwards, rinse your hands completely. If possible, don’t touch the water tap again due to the germs that can be found here. If you can, use a dry towel to turn off the faucet.
5. Finally, dry your hands properly, and don’t forget the spaces between your fingers. Take enough time for this as well. (5) Artificial fingernails are a special case. They can remain a hygienic risk factor even after proper washing, as moisture is retained longer in the barely visible cracks in the plastic. (6)

Now that we know when and how handwashing makes sense, let's discuss products. There are a few things to consider when choosing the right items. Natural soaps, for example, are usually made on a plant or animal fat basis. Industrial soaps, on the other hand, often include other ingredients such as dyes, fragrances, or preservatives. These ingredients can unnecessarily irritate sensitive skin.

In principle, soaps should be alkaline with a pH value of 8 to 11. This means that in the short term, they can destroy the "good" skin bacteria. This is not a major problem with healthy skin, as the pH value returns to a normal level after a few hours. However, excessive soap usage can damage the skin's natural barrier, making it easier for eczema, contact allergies, and irritation to develop. Some cleansers, however, have a skin-friendly pH value. (7)

HARTMANN, the company behind Sterillium®, offers various wash lotions that clean the hands both thoroughly and gently. Mild lotions such as Sterillium® Protect & Care Soap or Baktolin® pure are dermatologically tested, have a skin-friendly pH value of 5.5 and do not contain any dyes or perfumes. The skin-friendly products can have a positive effect on the skin of those who must wash their hands frequently, like doctors and nurses.

Some situations may only require washing your hands. Others may require disinfecting them. In many situations at home or with friends, for example, washing is quite sufficient.

However, disinfecting your hands makes sense if you encounter sick people, care for relatives, or if your immune system is weakened. It also helps to disinfect your hands in public places such as the subway or the supermarket. This is even more important if you don't have an option to wash your hands. During a flu epidemic or pandemic, it may also be better to disinfect your hands more frequently.

The best way to do this is to use a hand disinfectant, whether in liquid, gel or wipe form, which, in addition to being effective, also contains skin care components, such as Sterillium® Protect & Care Disinfectant Gel Hands.

Disinfect your hands correctly

However, hand disinfection also requires correct application. You should consider the following things:

• Make sure your hands are dry before you disinfect them.
• Pour enough disinfectant into the palm of your hand. 2-3 strokes from the dispenser are usually enough.
• Make sure to wet your entire hand with disinfectant.
• Pay special attention to the fingertips, the thumbs and the spaces between the fingers.
• Then rub the disinfectant in thoroughly for at least 30 seconds.
• Keep your hands moist throughout the procedure.

Good to know: Hand hygiene includes not only hand disinfection, hand washing and care, but also the use of examination gloves, if necessary. This applies primarily to professional staff, but can also be relevant for family caregivers.

Only intact skin can be fully disinfected. Thus, make sure to lubricate your hands because this gives them back what soap or disinfectants without care components has removed – primarily fat. (8)

To protect your hands from drying out, take care of them. Especially if you wash them a lot. As mentioned above, first wash your hands with lukewarm water and then dry them. It is best to apply a light cream or lotion regularly during the day and a moisturizing cream in the evening before going to bed. If you have particularly dry hands, you can also wear thin cotton gloves over your creamed hands at night. It is also important to apply cream to the sensitive cuticles, as they can tear quickly. (9)

Baktolan® balm, a sister product from Sterillium®, for example, is an intensive water-in-oil balm for dry, sensitive skin that is suitable for daily use. Its ingredients include allantoin, vitamin E, and panthenol, which can soothe skin irritation and redness and stabilize the acid mantle. Those who prefer a lotion that is absorbed quickly can also choose Baktolan® lotion. And those who have particularly sensitive skin can also choose the product variants without perfumes, for example. (10)

In the health care sector, examination gloves are part of the daily routine of medical professionals in many situations – be it when taking blood samples or treating wounds. But wearing gloves is also important for people who care for others at home, whenever there is a risk of becoming infected or transmitting pathogens to others. Therefore, examination gloves also belong to the elements of hand hygiene.

However, if you have to wear gloves frequently, you should consider a few things to avoid putting your own skin under unnecessary strain. If you want to protect your hands, you should:

• only put on gloves when your hands are completely dry
• wear the gloves only for as long as is necessary for the job in question
• disinfect your hands after taking off gloves
• apply lotion regularly to your hands after you have finished working, taking off and disinfecting

And a small tip at the end: even with gloves on, pathogens can be spread. So, as long as you are wearing them, you should touch as little as possible to avoid unnecessarily contaminating surfaces with viruses or bacteria.

Used at the right time and executed correctly, hand hygiene is an essential part of healthcare and saves millions of lives every year. That is why the World Health Organization (WHO) celebrates "World Hand Hygiene Day" every year on May 5th. The date was not chosen at random: The number 5 is meant to refer to the five fingers on each hand. Under the slogan "Act faster together. SAVE LIVES – Clean your Hands", the WHO wants to make people in the healthcare sector aware of the importance of clean hands and proper hand hygiene. It also aims to strengthen the collaboration among people and organizations to reduce infections and minimize the development of antibiotic resistance in healthcare settings. (11)
