Proper Hand Washing And Your Skin
In recent times, news of the novel Coronavirus (nCoV) outbreak has dominated our media. There are many precautionary instructions across many platforms informing the general public on protecting themselves as well as those around them to prevent the spread of harmful viruses, germs and illnesses. One of the most effective ways to stop germs and viruses from spreading is proper hand hygiene. Hand washing is an important part of hand hygiene.
Watch this video on Hand Washing Steps using the World Health Organization (WHO) Technique:
This should take between 40-60secs. Summary of steps are here.
The thing that concerns us about this WHO hand washing steps is the amount of water ‘wasted’ during the process of washing. This would present a challenge in water scarce countries like Singapore. Probably, a good additional step would be to use another towel tissue to switch on and off the tap if you are concerned about wasting water and contacting germs after you have finished washing.
Some frequently asked questions are:
- Should I use soap and water to wash my hands?
Ans: Germs can get onto your hands and items you touch throughout the day. Washing hands with soap and water is one of the simplest and most effective ways to remove whatever germs and chemicals that may be on them. However, it is important to choose your handwash wisely to prevent skin dryness and eczema especially if you have a pre-existing skin condition.
- Is Warm or Cold water more effective?
Ans: Either is fine as long as it’s clean. Washing with water that is too hot or too long may have other adverse effects like causing skin dryness.
- Bar Soap or Liquid is better?
Ans: Bar soap is fine as long as it is kept in a clean and dry dish, though there is still risk of contamination. For this reason, more people are switching to liquid soap.
- Must a soap be anti-bacterial?
Ans: No. Plain soap and water works well enough.
- Do I have to clean under my fingernails? How?
Ans: Yes, germs can accumulate under fingernails. Make sure to clean under nails by watching the video or image above.
- Towel or air dry?
Ans: Towel is fine but make sure the towel is clean if you are using one. Air dry is advisable if one is available as it helps to minimise contact.
- What if there’s no soap and water to wash my hands? Hand Sanitisers vs Water & Soap
Ans: Many commercially available alcohol-based hand sanitisers containing at least 60% alcohol can quickly kill most types of germs on hands but it may not kill certain bacteria and viruses that cause diarrhea. It is still best to wash hands before eating.
As there are many articles about the harmful effects of ethyl alcohol and BAC (benzalkonium chloride), common ingredients in hand sanitisers, it is highly recommended to use one with natural ingredients containing aloe vera gel, essential oils like tea tree, thyme and lavender etc. There are many youtube videos on home-made (DIY) hand sanitisers. However, there is a lack of studies on the efficacy of these DIY sanitisers against the host of viruses.
As we step up our vigilance, the frequency of hand washing will also increase. This can have an adverse effect on your skin, especially your hands, leading to hand dryness and eczema.
Two major types of skin reactions are Irritant Contact Dermatitis and Allergic Contact Dermatitis.
Irritant Contact Dermatitis is commonly caused by repeated and frequent use of hand hygiene products, healthcare professionals especially nurses being most susceptible. Skin reactions range from mild to severe, including skin dryness, irritation, itching and cracking which may lead to bleeding and weepy wounds. So whilst we learnt that hand sanitisers need to have an alcohol content of 60% and above to be effective in killing viruses, these products also cause skin irritation.
Potential irritants also include detergents and antimicrobial soaps. Hand hygiene products containing these substances damage the skin by progressively depleting the surface lipid barrier of skin, this results in deeper action of detergents into the superficial layers.
Allergic Contact Dermatitis is an allergy to some ingredient in a hand hygiene product. Reactions range from mild, localised, generalised to severe. In its most serious form, allergic contact dermatitis can even cause respiratory distress. Causes are typically fragrances, preservatives and less commonly, emulsifiers in liquid soaps, lotion, ointment and creams. Besides skin irritations, these toxic ingredients can potentially cause damage to our bodies when absorbed into our bloodstream.
