6 Wellness Myths Doctors Wish North Carolinians Would Stop Believing

North Carolina’s doctors write about 787 antibiotic prescriptions for every 1,000 people, against a national rate of 752, per the CDC’s most recent count.

Some of those are for viruses.

These are the wellness myths doctors wish North Carolinians would stop believing.

Note: This is general information, not medical advice. Guidelines are subject to change, so talk to a doctor about your situation.

1. Knuckle Cracking and Arthritis

One doctor cracked the knuckles on his left hand every day for 50 years and left his right hand alone as a control.

He found no arthritis in either hand, and the two looked the same after five decades.

It never wrecked his joints.

That work earned him an Ig Nobel Prize in 2009, the honor that celebrates research that makes people laugh, then makes them think.

Wider studies back up his experiment: Comparisons between knuckle-crackers and people who never crack a knuckle turn up no higher rate of arthritis in the crackers.

The crack itself comes from gas bubbles bursting inside the fluid that lubricates each joint, not bone grinding on bone.

Habitual crackers should still watch their grip strength, since a few studies link the habit to a weaker hold over time, even without arthritis attached to it.

2. Eight Glasses of Water a Day

The eight-glasses-of-water-a-day rule has no medical study behind it, despite sounding like doctor’s orders passed down for generations.

The National Academies of Sciences, Engineering, and Medicine puts an adult’s daily water target closer to 92 to 124 ounces instead.

That range, reported by the University of Rochester Medical Center, counts every drink and every bite of food that carries water.

A humid Carolina summer, a long run, or a stomach bug can push needs even higher.

Doctors give a simpler rule: Let thirst and urine color be the guide.

Pale means you’re fine.

Dark means it’s time to drink more.

3. Flu Shots and the Flu

Doctors keep hearing the same question every fall: Can a flu shot give you the flu?

It can’t.

The vaccine’s viruses are killed or weakened before they ever reach a syringe, so they can’t grow into an infection.

Soreness, a mild fever, or a headache the next day is your immune system doing its job, not a hidden case of the flu.

North Carolina’s flu season runs October through May, according to the state’s Department of Health and Human Services.

Doctors want shots in arms before that window opens, not after patients skip the vaccine over a myth.

4. Antibiotics for a Cold or the Flu

Patients request antibiotics at doctor’s offices across North Carolina anytime a cold or the flu drags on.

They can’t touch either.

Colds and the flu come from viruses.

Antibiotics only kill bacteria, so the drug has nothing to attack.

North Carolina’s doctors write about 787 prescriptions for every 1,000 people, above the national rate of 752, per the CDC’s most recent count.

That gap matters because unnecessary antibiotics breed resistant bacteria, the kind that stop responding to the drugs built to kill them.

A prescription can feel like progress at the pharmacy counter.

The relief can vanish months later, when a patient ends up with a harder infection to treat instead.

Fluids, rest, and an over-the-counter symptom reliever do the actual work while a virus runs its course.

5. Automatically Safe Natural Supplements

Natural supplements line drugstore shelves with the promise that nothing derived from a plant or a root can hurt you, a myth doctors hear in exam rooms across the state.

That’s not true.

The FDA doesn’t test or approve a supplement for safety before it’s sold, per the agency’s guidance.

No one checks first.

Manufacturers police themselves, deciding on their own whether an ingredient is safe and whether the label tells the truth.

The FDA can pull a dangerous product, but only after problems turn up, not before the product ever reaches a customer.

A federally funded study tracking emergency rooms from 2004 to 2013 estimated about 23,000 ER visits a year tied to supplement side effects.

Young adults turned up more often with heart problems from weight-loss or energy pills, while older adults choked on capsules that were hard to swallow.

6. Body Heat Loss Through the Head

People blame the head for losing most of the body’s heat once cold weather hits the Blue Ridge Mountains.

That’s not how heat works.

The myth traces back to an old U.S. Army field manual that estimated a bare head could lose 40% to 45% of the body’s heat.

A 2008 study found the number closer to 10%, roughly the head’s share of total skin.
