Heart disease remains one of the leading causes of death worldwide, and yet a substantial share of risk is shaped by things that are, at least partly, within reach: movement, sleep, diet, smoking, stress and blood pressure.
Move most days, not perfectly
The largest health return comes from moving from nothing to something. Around 150 minutes a week of moderate activity is the usual target, but a brisk daily walk already shifts risk meaningfully. Consistency beats intensity.
Know your blood pressure
High blood pressure is symptomless for years, which is exactly why it does damage. If you have never had it measured, that is the single most useful thing on this list.
Six habits worth building
- Walk briskly for 20–30 minutes most days.
- Cook at home more often than not — restaurant and packaged food carries far more salt.
- Prioritise sleep; short sleep is independently associated with cardiovascular risk.
- If you smoke, stopping is the highest-value change available to you. Ask us about support.
- Keep alcohol modest.
- Have your blood pressure and cholesterol checked at the intervals your clinician suggests.
Patients often expect a dramatic intervention. Usually the answer is undramatic, repeated for years.
When to seek help promptly
Chest pain or pressure, breathlessness that is new or worsening, fainting, or pain spreading to the arm or jaw all warrant urgent assessment. Do not wait to see whether it passes.
Understanding your numbers
Blood pressure is written as two figures: the pressure as the heart contracts, over the pressure as it relaxes. Both matter. Readings taken at home over several days are often more representative than a single measurement in a clinic, where nerves can push the number up — a well-recognised effect. If you monitor at home, sit quietly for five minutes first, keep your arm supported at heart height, and take two readings a minute apart.
Cholesterol is similar in that a single figure means little alone. Clinicians look at the balance between different types, alongside your other risk factors, to estimate overall risk over the coming years.
Stress, and why it is not just in your head
Sustained stress raises blood pressure, disrupts sleep and tends to push people toward the habits that make cardiovascular risk worse. Addressing it is not a soft add-on to heart health — it is part of the same picture. What works varies: exercise, time outdoors, protected time away from screens, or speaking to someone. The important thing is that it is genuine recovery rather than distraction.
Family history is information, not destiny
Having a parent or sibling who developed heart disease early does raise your risk, and it is worth telling us about. But it also means earlier screening and earlier intervention are available to you — which is precisely how that inherited risk gets managed. People with a strong family history who address blood pressure, cholesterol, smoking and activity often end up at lower overall risk than someone with no family history and none of those things addressed.
