You're washing your socks WRONG: Microbiologist reveals how to clean yours properly - and why you should always IRON them

A microbiologist warns about the risks of improperly cleaned socks and shares effective washing techniques.

Properly washing socks prevents infections

Dr Primrose Freestone, a microbiologist at the University of Leicester, highlights the importance of washing socks correctly to prevent microbial growth. He notes that feet harbor millions of bacteria and fungi. To clean socks effectively, he recommends washing them at a minimum of 60°C using an enzyme-based detergent. If the washing machine can't reach this temperature, he advises ironing the socks, especially with a steam function, to eliminate any lingering pathogens. Dr Freestone emphasizes that socks can collect harmful microbes that thrive in the warm, humid environment of our feet, making proper cleaning essential.

Key Takeaways

✔️

Feet host millions of bacteria and fungi, making sock hygiene crucial.

✔️

Washing socks at 60°C with enzyme detergents is highly recommended.

✔️

Ironing socks can eliminate bacteria if washing at high temperatures is not possible.

✔️

Socks act as microbial sponges, picking up harmful pathogens.

✔️

Improper sock cleaning can lead to infections in shared spaces.

✔️

Understanding sock hygiene can significantly improve personal health.

"Feet can be a host for up to 1,000 different bacterial and fungal species."

Dr Freestone explains the diverse microbial environment on feet that can affect sock hygiene.

"If your washing machine cannot manage a 60°C sock-microbe-killing temperature wash, then a hot iron will do the job."

Dr Freestone emphasizes the importance of using higher temperatures to kill bacteria effectively.

"You can pass on infections from dirty socks, such as verrucas, which are highly contagious."

Dr Freestone warns of the potential health risks linked to uncleaned socks.

"Some residual bacteria remain in socks if the wash is not a very hot one."

This fact underlines the need for public awareness regarding proper sock care.

This guidance sheds light on the often-overlooked area of sock hygiene and its implications for overall health. With many people unaware of the microbe levels on their feet, Dr Freestone's research serves as a wake-up call. The alarming revelation that socks can carry up to 1,000 different microbes, some causing serious conditions, places a spotlight on the overlooked risks of improper laundry habits. Beyond simply freshening socks, the call for higher washing temperatures reveals an ongoing need for public awareness regarding health and hygiene practices in daily life.
