How Often Should You Wash Towels to Avoid Germs?

Many people assume their towels are clean because they only dry “clean” bodies – but that belief can be exactly where the problem starts.

In everyday life, towels are often at the very bottom of the cleaning list. Bed linen is changed regularly, as is underwear, yet the bath towel can hang on its hook for weeks. Microbiologists say this is a mistake that can lead to anything from spots to serious skin infections.

Why towels quickly become a breeding ground for germs

At first glance, a towel seems harmless: soft, dry and clean. After all, it only removes water from the skin after a shower – doesn’t it? In reality, it is not that straightforward.

What builds up in towel fibres

Every time you dry yourself, the fabric collects:

• dead skin cells
• body oils and sweat
• residue from shower gel, shampoo, make-up and creams

This combination becomes embedded deep in the fibres. If the towel is then left damp in a warm bathroom, it creates the ideal environment for germs.

Moisture + warmth + skin residue: this combination enables bacteria and fungi to multiply rapidly – often after only a few uses.

Germs on towels and the health risks

US microbiologist Philip Tierno of New York University warns that a towel can accumulate considerably more germs after just two or three uses. If it then remains unwashed in the bathroom for days, the risk increases of:

• skin irritation and itching
