Dubai Expert Reveals Why Phones Harbour More Germs Than Toilets And Cleaning Tips

A Dubai-based microbiologist has warned smartphone users that their devices may carry large amounts of bacteria due to frequent handling and exposure to multiple environments throughout the day. Neethu Sureshkumar, a microbiologist working in Dubai, highlighted the importance of regularly cleaning mobile phones, saying that the devices can become breeding grounds for germs because people carry them almost everywhere.

In a video shared on Instagram on May 16, Sureshkumar cautioned users about the hidden bacteria present on smartphones. She compared mobile phones to commonly touched surfaces and asked users to consider the possibility that their devices could carry more bacteria than a toilet seat. While the comparison is often used to highlight hygiene concerns, experts say the type and quantity of microbes found on phones depend on individual habits, cleaning routines and the environments in which devices are used.

According to Sureshkumar, smartphones become "bacteria magnets" because they accompany users throughout their daily routines. Unlike many household objects that remain in one place, phones are constantly moved between different environments, allowing microorganisms to transfer easily onto their surfaces. From workplaces and public transport to homes and recreational spaces, phones frequently come into contact with surfaces that may carry germs.

She pointed out several common situations where smartphones can accumulate bacteria. In offices, phones are often placed on shared desks or workstations that are touched by multiple people. At home, many users keep their devices on kitchen counters while preparing food, creating opportunities for contamination. At gyms, phones may be placed on workout equipment or other surfaces exposed to sweat and bacteria. Sureshkumar also highlighted that some people use their phones in washrooms, which can increase exposure to microorganisms.

The microbiologist advised users to make smartphone cleaning a regular habit to reduce the risk of germ transfer. She recommended cleaning devices with appropriate disinfectant products and avoiding the use of harsh substances that could damage screens or internal components. Users should also clean phone cases regularly, as covers can collect dirt, oil and bacteria over time.

Experts generally recommend using manufacturer-approved cleaning methods, such as wiping phones with a microfiber cloth and suitable alcohol-based disinfectant wipes where permitted. Users should also wash their hands frequently, especially before eating, and avoid placing phones on visibly dirty surfaces. Maintaining personal hygiene remains one of the most effective ways to reduce the spread of germs from frequently touched objects.

With smartphones now serving as essential tools for communication, work, entertainment and online transactions, regular cleaning has become an important part of everyday hygiene. Sureshkumar's warning serves as a reminder that devices handled throughout the day require the same attention as other frequently touched items. While smartphones are unlikely to pose a serious health risk for most people, keeping them clean can help minimise unnecessary exposure to bacteria and prevent the transfer of germs between surfaces, hands and faces.
