The short explanation
Yes. Second-hand smoke contains many of the same harmful chemicals as smoking yourself, and regular exposure increases the risk of heart disease and stroke in people who do not smoke. There is no level of second-hand smoke that is considered harmless. Making the home fully smoke-free protects you and anyone else in the house, including children and older relatives. Opening windows or smoking in another room reduces but does not remove the exposure.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Smoke particles settle on furniture, clothes and curtains and continue to be inhaled, sometimes called third-hand smoke.
- If you have asthma, high blood pressure or diabetes, or are pregnant, the effects can be greater.
- Many government hospitals have tobacco cessation clinics. Encouraging your husband to get support, rather than only asking him to stop, often works better.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot measure how much your heart has been affected. A doctor can assess your overall heart risk.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How much does second-hand smoke affect my heart risk?
- Are there quit-smoking services you can recommend for my husband?
- Should my BP and cholesterol be checked?
- Does it affect my breathing tests?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 for chest pain, pressure or tightness, sudden breathlessness, or fainting.
Raise it at a routine appointment
- Book a routine check-up to review your heart risk, and ask about local tobacco cessation support for your husband.

Did this answer your question?
Whatever you choose is filed against this version of the answer, never against you, and it is never shown as a count.
“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
Saving, following up and reporting are all private. Nothing you do on this page is visible to other readers or to the doctor who wrote it, unless you ask a question.
