Making small, realistic changes to your daily habits can support your heart health and significantly reduce your risk of cardiovascular disease (CVD), including coronary heart disease, stroke and heart failure.Understanding how your lifestyle choices affect your heart is an important first step. Our Heart Age Calculator can help estimate your risk of experiencing a heart attack or stroke based on a range of risk factors. If your heart age is higher than your actual age, your CVD risk may be elevated.

In Australia, more than one‑third of CVD‑related deaths in people under 65 are attributed to smoking.
Nicotine from smoking or vaping damages blood vessels and encourages plaque build‑up. This reduces the flow of blood and oxygen around your body, increasing your risk of a heart attack, stroke or heart failure.
Quitting smoking and vaping altogether is one of the most effective ways to lower your CVD risk. Cutting back does not provide the same benefits.
Your GP or local clinic can help you quit through options such as nicotine replacement therapy, medicine, and referrals to psychologists or counsellors. Support is also available through Quit resources.

Around one in three people in Australia aged 14 and over drink risky amounts of alcohol each week. Your risk of CVD, including high blood pressure, heart failure and stroke, increases in line with the amount of alcohol you consume.
Growing evidence suggests that drinking any amount of alcohol increases your risk of CVD, meaning there’s no “safe” limit you can stick to without causing harm to your heart.
Some of the many ways in which alcohol affects your heart include:
Limiting your alcohol intake is essential for reducing CVD risk. At a minimum, keep your consumption within the recommended guidelines (≤10 standard drinks/week and ≤4 at one time).
To support your heart health, have at least two alcohol-free days each week. If you’re going out with friends, consider non-alcoholic options. When you are having alcohol, alternate each alcoholic drink with a non-alcoholic option, and drink plenty of water to avoid dehydration. The best way to support your heart health and reduce CVD risk is to avoid alcohol entirely. If you’re sober curious or need help to reduce your drinking, ask your GP or clinic for support and resources.

Around 46% of adults aged 18+ fail to meet Australia’s physical activity guidelines, with 39% of this group living completely inactive lives.
Living an inactive, sedentary lifestyle significantly increases your risk of CVD. Low levels of physical activity are linked to higher blood pressure and cholesterol, weight gain, reduced blood sugar control, and poor fitness levels.
However, regular physical activity improves mental and physical health, and reduces many risk factors for CVD, including overweight and obesity, high blood pressure and high cholesterol levels.
Many people living in Australia are currently not eating enough vegetables, fruits and whole grains, instead reaching for fast, easy alternatives like ultra-processed foods and takeaway options.
If your diet is high in sodium or added sugars, or contains lots of processed, fried or sugary foods, this increases your risk of CVD.
Replacing the highly processed foods in your diet with whole food alternatives can significantly improve your blood pressure and cholesterol levels, support your immune system and help manage weight gain, improving your heart health and CVD risk.
Small dietary swaps can have enormous benefits for your heart health. Try the following:
Chronic stress, poor mental health, isolation and loneliness, and inadequate sleep are significant risk factors for CVD. Each of these can cause chronic inflammation, increase blood pressure and damage your arteries, potentially causing heart disease or stroke.

Stress, poor sleep and mental illness can also drive other heart-harming behaviours like smoking, excessive drinking, poor dietary habits, and physical inactivity. It’s important to intervene or seek help to avoid becoming stuck in a vicious cycle.
Ask your GP or clinic to help you manage stress, mental health struggles, insomnia or other sleep issues.
Your lifestyle choices and habits can have a profound impact on your heart health and CVD risk. By adopting these practical strategies, you can greatly reduce your risk of developing CVD and improve your overall quality of life.
