To maintain a clean and comfortable living environment, many people spend time cleaning their homes every day. However, in life, there are objects and areas that, although they appear clean on the outside, actually contain a lot of bacteria and pose serious health risks. Here are four typical examples of things that seem clean but actually contain many hygiene problems.

Shower head

The shower is an indispensable device in the bathroom, serving daily bathing. However, because the shower head’s drainage holes are very small, dirt and impurities easily accumulate over time and easily cause blockages. In the humid environment of the bathroom, bacteria also grow very easily.

This accumulation not only reduces the efficiency of water flow but can also pollute the water source. Bathing with water from a clogged shower can irritate the skin, leading to symptoms such as itching or allergies.
