Does climbing stairs actually do anything for my heart?
People who climb stairs regularly show a clearly lower risk of dying from heart disease in large studies. Even five minutes a day appears to be enough to improve your cardiometabolic profile.
Stair climbing is clearly linked to a lower risk of dying from heart-related causes. In a combined analysis of five studies involving more than 455,000 participants, people who climbed stairs regularly had a relative risk of 0.61 for dying from cardiovascular disease, compared with people who did not. The risk of dying from any cause was also lower, with a relative risk of 0.76. This does not prove that stair climbing is the cause, but the association is large and consistent.
Small amounts already make a difference. Even around 5 minutes of stair climbing per day was linked, in a large European study of more than 12,000 adults, to a more favourable cardiometabolic profile: better figures for weight, waist circumference, triglycerides, cholesterol and blood sugar. That amount is roughly equivalent to 64 minutes of walking per day. No ceiling was visible: more stair climbing appeared to keep delivering slightly more benefit.
Stair climbing also appears to be linked to fewer heart attacks, strokes and cases of heart failure, but the exact numbers are not available from the published research used as a source here. That makes this finding more tentative than the figures on the risk of dying.
In practical terms, taking the stairs instead of the lift is one of the easiest ways to build a little more movement into your day. Every floor counts.
This answer draws on two studies. The findings on the risk of dying come from a combined analysis of five studies involving more than 455,000 participants. The findings on body weight, cholesterol and blood sugar come from a large European study of more than 12,000 adults in which movement was measured with a sensor worn on the thigh. Both studies measure association, not cause and effect: people who climb stairs may also live more healthily in other ways. The researchers themselves point to this limitation. The evidence on events such as heart attacks, strokes and heart failure is thinner because the precise figures do not appear in the available sources.
Does reducing inflammation help your heart in the long term?
Targeted treatment to reduce inflammation, particularly with low-dose colchicine, measurably reduces the risk of serious heart events in people with coronary artery disease. Discuss with your cardiologist whether this is relevant for you, because not every drug works and there are safety considerations that require careful weighing.
How harmful is prolonged stress really for my heart?
Prolonged stress measurably increases your risk of heart and vascular disease, particularly through work-related stress (10–40% extra risk in large population studies). The effect is real, but smaller than that of smoking or high blood pressure.
Is the Mediterranean diet really good for your heart, and why?
For people at increased heart risk, the Mediterranean diet is the best-supported dietary choice currently available. Both large studies in people and dozens of population studies confirm a lower risk of heart attack and stroke.
Are calcium supplements bad for your heart?
Calcium supplements may be associated with an increased heart risk, but not all studies confirm this. It is best to get calcium from your diet, and discuss with your doctor whether a supplement is truly necessary for you.
Can losing weight noticeably improve my blood pressure and cholesterol?
Losing weight noticeably lowers your blood pressure and improves your cholesterol profile, but which value improves the most depends on your diet. And if the weight comes back, most of the gains disappear too.
Is interval training (HIIT) better for my heart than regular cardio?
HIIT produces a greater improvement in heart and lung fitness than regular cardio, even in people with a heart condition, though the differences are modest.
