In a world of modern medicine, we often think of advanced treatments, powerful medications and technology as the key to saving lives. However, one of the most effective ways to prevent disease is surprisingly simple: washing hands properly.
Our hands come into contact with many surfaces throughout the day — door handles, money, phones, public transport rails and shared objects. These surfaces can carry germs such as bacteria, viruses and parasites. When we touch our eyes, nose, mouth or food with unwashed hands, these germs can easily enter the body and cause illness.
Poor hand hygiene is linked to the spread of common infections such as diarrhoea, respiratory infections and food-borne illnesses. In children especially, diseases caused by poor hygiene remain a major cause of sickness and hospital visits.
Effective handwashing removes harmful germs before they can spread. It is especially important at key moments during the day. Hands should be washed before preparing or eating food, after using the toilet, after changing a child’s nappy, after coughing or sneezing, and after handling waste or caring for someone who is sick.
The correct handwashing technique is also important. Hands should be washed with clean water and soap for at least 20 seconds. This includes rubbing the palms, the backs of the hands, between the fingers, under the nails and around the thumbs. After rinsing thoroughly, hands should be dried with a clean towel or allowed to air-dry. When soap and water are not available, alcohol-based hand sanitisers can be used as an alternative.
Teaching children the habit of regular handwashing is particularly important. Children who learn proper hygiene grow into adults who protect not only themselves but also the wider community.
In many parts of the world, serious diseases can spread quickly when hygiene practices are neglected. Yet the solution is often within reach: clean water, soap and awareness.
