Less confusion. More clarity.

Nobody is being told off here. Most of these sound perfectly reasonable, which is exactly why they spread so easily. Let us go through them together.

What you may have heard

“Inhalers are addictive and weaken the lungs.”

What the evidence says

Inhalers are not addictive. A preventer inhaler calms the inflammation in your airways so that you need less rescue medication, not more.

Needing an inhaler means a condition is being treated, not a habit being formed. Stopping the preventer because you feel well is the most common reason people end up in a flare.

What you may have heard

“A cough that lasts a few weeks is nothing to worry about.”

What the evidence says

Beyond eight weeks, a cough is called chronic and deserves a proper look.

Most causes are manageable: post-nasal drip, asthma, reflux. The point is not alarm. It is knowing when someone should take a look.

What you may have heard

“Antibiotics will clear my cough faster.”

What the evidence says

Most coughs are viral. Antibiotics do nothing against viruses and can cause side-effects and resistance.

Antibiotics have a clear role in bacterial infections such as pneumonia. That decision belongs in an assessment, not at a pharmacy counter.

What you may have heard

“Vaping is just water vapour.”

What the evidence says

A vape delivers an aerosol of nicotine, flavouring chemicals and fine particles into the lungs.

It may be less harmful than smoking for an adult who switches completely, but it is not harmless, and it is not for young lungs.

What you may have heard

“Only smokers get lung disease.”

What the evidence says

Air pollution, indoor smoke, dust at work, infections and genetics all matter.

Many people with asthma, COPD or fibrosis have never smoked. Blame helps nobody. An assessment does.

What you may have heard

“Breathlessness is a normal part of getting older.”

What the evidence says

Ageing reduces reserve, but new or worsening breathlessness always has a cause.

Heart, lungs, low iron and fitness are all treatable contributors. Do not accept a symptom without an explanation.

What you may have heard

“Steam and home remedies can cure asthma.”

What the evidence says

Steam may soothe. Asthma is inflammation in the airways and needs proper control.

Comfort measures are welcome alongside treatment, never instead of it. There is no cure claim in honest medicine, only good control.

What you may have heard

“TB is a disease of the past.”

What the evidence says

Tuberculosis is still common, and it is curable when treatment is completed.

A cough beyond two weeks with fever, night sweats or weight loss should be tested. Early testing protects the whole household.

How we talk about this

Drama gets replaced with clarity. Superiority gets replaced with guidance.

Never this

“This viral advice is completely stupid.”

“5 shocking signs your lungs are damaged.”

Always this

“You have probably heard this. Here is what the evidence tells us.”

“Five symptoms that should not be ignored.”
