Money, whether paper or coins, passes through countless hands while accumulating a variety of germs along the way. It’s a notorious carrier of bacteria like E. coli and Staphylococcus aureus, which can cause a range of illnesses.
Washing your hands thoroughly after handling money stops these unwanted passengers from reaching your face or food. A quick 20-second scrub with soap and water is your first line of defense against these germs.
2. Not Replacing Your Toothbrush Regularly

Your toothbrush, though vital for oral hygiene, can become a breeding ground for bacteria over time. Worn bristles are less effective at cleaning and can harbor harmful microbes, potentially leading to gum disease and other oral health issues.
Dentists advise replacing your toothbrush every three to four months, or sooner if the bristles are frayed. A fresh toothbrush ensures optimal cleaning and reduces the risk of introducing bacteria into your mouth. Don’t let your toothbrush become a liability – replace it regularly for a healthy smile.
3. Using the Same Towel for Too Long

Damp towels, especially in humid environments, create a perfect breeding ground for bacteria and mold. That musty smell? It’s a clear sign your towel needs a wash. Using the same towel repeatedly can lead to skin irritations and infections.
Aim to replace your bath towel every three to four days and hang it to dry properly after each use. By keeping your towels dry and switching them out frequently, you create an environment that’s less hospitable to germs.
4. Forgetting to Clean Your Phone

Your phone is practically an extension of your hand, constantly in contact with various surfaces and your face. Studies have shown that cell phones can harbor more bacteria than a toilet seat.
Regularly wipe down your phone with a disinfectant wipe to minimize germ spread. It’s a small action that can significantly reduce your exposure to harmful bacteria and keep your phone clean. Your phone is a high-touch surface, so keeping it clean is essential.
5. Reusing Water Bottles Without Washing Them

Reusable water bottles are great for the environment, but they can also become a breeding ground for bacteria if not cleaned properly. The moist environment inside, combined with residue from your mouth and hands, creates a perfect environment for microbial growth.
Wash your reusable bottle with soap and hot water after each use. This simple practice can help prevent the buildup of harmful bacteria and keep your water tasting fresh. Don’t let your eco-friendly choice inadvertently become a health hazard.
6. Not Washing Your Reusable Grocery Bags

Reusable bags are a positive step for the environment, but they can also harbor bacteria, especially if you carry raw meat or produce in them. Food spills and leaks can contaminate the bags, creating a potential health risk.
Wash your reusable bags regularly according to the care instructions to keep them clean and safe for carrying your groceries. This helps prevent cross-contamination and ensures your bags remain hygienic.

Your hands are constantly interacting with the world, picking up germs from various surfaces. Touching your face transfers these germs to your skin, increasing the risk of breakouts and infections.
Be mindful of this habit and try to avoid touching your face unnecessarily. If you need to touch your face, make sure your hands are clean first. Breaking this habit can significantly reduce the transfer of germs and help keep your skin clear.
8. Sharing Personal Items

Sharing personal items like razors, towels, or makeup brushes can facilitate the spread of germs and infections. Even with close friends or family, it’s best to avoid sharing these items.
Personal items can harbor bacteria and viruses specific to an individual. Keeping your personal items to yourself is a simple way to protect both yourself and others from unnecessary exposure.

Clean brushes not only promote healthier skin but also prevent bacterial buildup that can cause infections. Make it a habit to clean your brushes regularly to keep your skin looking and feeling its best.
