Drinking directly from beverage cans

Many people have a habit of popping open and drinking directly from canned beverages. Actual microbiological tests confirm that the surface of can lids easily accumulates dust and may contain bacteria such as E. coli or Staphylococci during storage and transportation. Users should wipe the can rim clean before drinking.

Folding blankets immediately after waking

During sleep, the body secretes sweat and sheds dead skin cells. Folding blankets immediately after waking traps bacteria and dust mites in a humid environment.

A 2005 study by Doctor Stephen Pretlove of Kingston University (UK) indicated that leaving blankets open helps the bed dry out, causing dust mites to dehydrate and die. The correct method is to open windows and spread the blanket flat for about 10 minutes before folding.

Rinsing raw meat under running water

The U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA) warn against rinsing raw meat under strong running water. This action can spray Campylobacter and Salmonella bacteria nearly mot meter away, contaminating the sink and surrounding dishes. For safety, meat should be soaked in a basin of water, then gently rinsed, and raw food kept away from clean dishes.

Flushing the toilet without closing the lid

A 2022 study published in Scientific Reports by the University of Colorado Boulder (U.S.) showed that thousands of tiny water droplets containing bacteria are ejected into the air at hai meters/second when a toilet is flushed. Professor John Crimaldi, who led the study, stated that these particles can spread up to 1,5 meters high and remain suspended in the air for several minutes. The best practice is to close the toilet lid before flushing.

Bringing phones into the restroom

According to research by microbiologist Charles Gerba of the University of Arizona (U.S.), mobile phones carry 10 times more bacteria than a toilet seat. During use, bacteria spread and adhere to the phone, then re-infect the face and hands. Users should avoid bringing devices into the restroom or sanitize the phone's surface after use.

Using kitchen towels for too long

A study by German scientists published in Scientific Reports revealed that sponges and kitchen towels are among the most bacteria-laden items in the home. They can contain densities of up to 45 billion bacteria/cm2, including Moraxella osloensis bacteria, which causes unpleasant odors. Experts advise changing kitchen towels every hai weeks, and regularly washing and drying cleaning tools.

According to the U.S. Department of Agriculture (USDA), users can sanitize sponges by wetting them and microwaving for mot minute, or by placing them in a dishwasher on a hot-dry cycle to kill up to 99% of bacteria.

Soaking dishes in soapy water

Soaking dirty dishes in a basin of soapy water at room temperature creates an ideal environment for bacteria to multiply exponentially. CDC standards require dishes to be rinsed thoroughly under running water, then left in a dry place to drain completely to prevent bacterial growth.

Brushing teeth immediately after eating

Many people have a habit of brushing their teeth right after a meal. However, according to the American Dental Association (ADA), the oral environment is highly acidic after eating, which softens tooth enamel. Brushing at this time can erode enamel. Users should wait 30 to 60 minutes after eating before brushing their teeth.
