Good hygiene is about much more than looking clean. Daily habits influence skin health, oral health, body odor, and even the risk of infections. Surprisingly, some of the most common hygiene mistakes are things people do every day without realizing they may not be the healthiest choices.

The good news is that small adjustments can make a big difference. Here are five hygiene mistakes that many people make—and practical ways to avoid them.

1. Touching or Picking Your Nose

It may seem harmless, but frequently touching or picking the nose can introduce bacteria and viruses into the nasal passages.

Potential problems include:

• Increased risk of infections
• Nasal irritation
• Minor bleeding
• Spread of germs from hands to the face

Better habit:

• Wash hands regularly.
• Use tissues when necessary.
• Keep nasal passages moist if dryness is a problem.

2. Not Replacing Toothbrushes Often Enough

Many people continue using the same toothbrush long after it should be replaced.

Over time:

• Bristles become worn
• Cleaning effectiveness decreases
• Bacteria may accumulate

Dental professionals generally recommend replacing a toothbrush every 3–4 months, or sooner if the bristles become frayed.

Better habit:

• Replace toothbrushes regularly.
• Store them upright and allow them to air dry.

3. Reusing Towels for Too Long

Towels absorb:

• Moisture
• Dead skin cells
• Natural oils
• Environmental bacteria

When left damp, they can become an ideal environment for microbial growth.

Better habit:

• Allow towels to dry completely between uses.
• Wash bath towels every few uses.
• Replace towels that develop persistent odors.

4. Cleaning Ears With Cotton Swabs

Many people use cotton swabs to clean inside the ear canal.

Ironically, this can sometimes push earwax deeper into the ear rather than removing it.

Potential problems include:

• Earwax impaction
• Irritation
• Injury to the ear canal
• Damage to the eardrum

Better habit:

The ears are usually self-cleaning. Clean only the outer ear unless a healthcare professional recommends otherwise.

5. Forgetting Frequently Touched Objects

Many people focus on personal hygiene but forget about items touched dozens of times every day.

Examples include:

• Smartphones
• Keyboards
• Remote controls
• Door handles
• Glasses

These surfaces can collect dirt, oils, and microorganisms over time.

Better habit:

• Clean devices regularly according to manufacturer recommendations.
• Wash hands after touching frequently used public surfaces.

Bonus: Washing Hands Too Quickly

One of the most common hygiene mistakes is washing hands for only a few seconds.

Health experts generally recommend:

• Using soap and water
• Scrubbing for at least 20 seconds
• Cleaning between fingers and under nails
• Drying hands thoroughly

Proper hand hygiene remains one of the most effective ways to reduce the spread of germs.

Signs Your Hygiene Routine May Need Improvement

You may want to reevaluate certain habits if you frequently experience:

• Persistent body odor
• Recurrent skin irritation
• Frequent dental problems
• Repeated minor infections
• Dry or irritated skin from over-cleaning

Remember, good hygiene is about balance—not excessive cleaning.

The Bottom Line

Many hygiene mistakes are surprisingly common because they become part of everyday routines. Touching the face frequently, neglecting toothbrush replacement, reusing damp towels, cleaning ears improperly, and forgetting to sanitize commonly touched objects can all affect health over time.
