As the world marked Global Handwashing Day on October 15, health experts are reminding everyone that something as simple as washing and properly drying your hands can make a profound difference to public health.

This year’s theme, ‘Clean Hands Are Within Reach’, highlights that good hand hygiene goes beyond soap and water, because how we dry our hands is just as important.

“Health experts state that more than 80% of illnesses can be transmitted by the hands, which is why everyday hand hygiene is key to reducing the spread of infections that cause illness,” says Samantha Choles, communications manager at the Paper Manufacturers Association of South Africa (PAMSA).

However, Choles notes that washing is only half the job. According to the US Centers for Disease Control and Prevention (CDC), wet hands can transfer germs up to 1 000 times more easily than dry ones.

Numerous studies have compared warm-air and jet dryers with disposable paper towels. The common finding is that paper towels remain the most hygienic for drying hands in public washrooms.

They remove residual moisture and bacteria more effectively, while limiting the spread of germs into the air – which is why they are recommended for hospitals and clinics.

Balancing hygiene and sustainability
Concerns often arise about the environmental impact of disposable paper towels. Choles reassures the public that tissue and paper-towelling products are made from sustainably sourced virgin wood fibre and recycled paper, such as used office paper.

“PAMSA’s tissue manufacturing members subscribe to forest certification bodies to ensure the responsible sourcing of raw materials,” she explains.

“Modern mills use renewable energy and closed-loop water systems during production, and you don’t need electricity to dry your hands with a paper towel.”

When paper towels are not available
If paper towels are not accessible, Choles says air dryers are a good alternative, provided they are used correctly:
Wash thoroughly first by using soap and running water for at least 20 seconds, cleaning all parts of the hands.

Shake hands gently over the sink to remove as much water as possible. Keep your hands still and cupped under the dryer until dry (about 30–40 seconds). Avoid touching surfaces afterward. Use your elbow or sleeve to open doors if possible.

As the world continues to prioritise health and hygiene, Global Handwashing Day serves as a timely reminder that clean, dry hands are within reach, and that small daily habits can protect communities from disease.
