15 Bad Hygiene Habits That Could Be Harming Your Health

Maintaining proper hygiene is crucial for staying healthy, but certain overlooked habits can have serious consequences. Here are 15 hygiene missteps that experts warn could harm your health and how to correct them.

1. Skipping Dental Hygiene

Brushing and flossing daily is more than just cosmetic; it’s crucial for preventing cavities, gum disease, and even systemic issues like heart disease. “Swollen gums and bad breath are just the start,” says Natasha Lee, DDS. Gum disease, if untreated, may lead to tooth loss and increase risks of cardiovascular conditions.

2. Reusing Towels Too Often

Towels trap moisture, making them a breeding ground for bacteria. Sharing or repeatedly using damp towels can spread infections like staph, meningitis, and even chlamydia. “Frequent laundering is essential,” advises skin expert Janine Frances.

3. Overwearing Contact Lenses

Leaving contact lenses in for too long can lead to severe eye infections, including corneal ulcers. “It’s like wearing the same dirty underwear daily,” warns ophthalmologist Alan Mendelsohn, MD. Proper cleaning and timely replacement of lenses are non-negotiable for eye health.

4. Not Washing Your Face Before Bed

Failing to cleanse your face nightly can trap dirt and oil, leading to breakouts and clogged pores. Eye makeup, in particular, can harbor bacteria, causing styes or even infections that threaten vision. A quick wash with a gentle cleanser is essential for healthy skin.

5. Sharing Grooming Tools

Using someone else’s toothbrush or razor may spread bacteria and viruses, including hepatitis and HIV. Hairbrushes can transmit lice and skin infections. “Sharing is caring, except when it comes to personal grooming,” notes the American Dental Association.

6. Rarely Washing Your Bedding

Unwashed sheets can harbor dust mites, bacteria, and fungi, leading to skin irritations and respiratory issues. “Launder sheets weekly to avoid serious infections like staph,” Frances advises.

7. Walking Barefoot in Public Showers

Public showers are hotspots for fungal infections like athlete’s foot and nail fungus. These conditions are stubborn and can cause lasting damage. Flip-flops or water shoes offer a simple defense.

8. Using the Same Toothbrush for Too Long

A toothbrush accumulates bacteria over time and should be replaced every 3–4 months. Using an old toothbrush can worsen gum disease and increase bacteria in your mouth. Store it upright to let it dry properly between uses.

9. Not Washing Makeup Brushes

Dirty makeup brushes accumulate oils and bacteria, leading to breakouts and skin infections. Dermatologists suggest washing them weekly with gentle soap to prevent clogged pores and irritation.

10. Leaving in Tampons Too Long

Failing to change tampons regularly can result in toxic shock syndrome, a rare but life-threatening infection. Symptoms include fever and vomiting, and severe cases may lead to organ failure^1. Always follow usage guidelines and consider alternative menstrual products like menstrual cups

11. Ignoring the Back of Your Neck and Ears

These areas are often overlooked during showers but can accumulate sweat and bacteria, leading to infections and odors. A thorough scrub ensures total cleanliness and reduces the risk of irritation.

12. Not Washing Reusable Water Bottles

Reusable bottles, if not cleaned regularly, can harbor bacteria like E. coli. This can lead to stomach infections and other health problems. “Clean bottles daily and pay attention to caps and hard-to-reach spots,” says Frances.

13. Wearing Shoes Indoors

Shoes can carry bacteria, allergens, and dirt from the outside, contaminating your living space. Studies show that shoes can harbor over 400,000 units of bacteria, including E. coli. Adopting a no-shoes policy helps maintain a cleaner home environment.

14. Neglecting to Wash Produce

Unwashed fruits and vegetables can carry bacteria and pesticides that lead to food poisoning or long-term health risks like respiratory problems. Rinsing produce thoroughly before consumption is an easy way to avoid these issues.

15. Biting Your Nails

This habit introduces bacteria from your hands to your mouth, increasing the risk of infections. “Keep nails trimmed and clean, and find alternative stress-relief habits,” advises dermatologist Romit Bhattacharya, MD.
