Can people with heart problems use a sauna?

Many people with heart conditions can use a sauna, but it is not suitable for everyone. Heat makes the heart work harder, so safety depends on the type of heart problem and how well it is controlled.

If you have angina, heart failure, an irregular heartbeat, or have had a recent heart attack, you should be especially careful. A GP or cardiologist can advise whether sauna use is safe for you.

How sauna heat affects the heart

In a sauna, the body tries to cool itself by increasing blood flow to the skin and making the heart beat faster. This can lower blood pressure and put extra strain on the cardiovascular system.

For someone with a healthy heart, this is usually manageable. For someone with heart disease, it may trigger dizziness, palpitations, shortness of breath, or chest discomfort.

Who should avoid saunas?

People with unstable angina, severe aortic stenosis, uncontrolled high blood pressure, or recently worsened heart failure should generally avoid saunas unless a doctor says otherwise. Those who have recently had surgery, a heart attack, or a stroke also need medical advice first.

If you feel unwell, dehydrated, feverish, or have symptoms such as chest pain or breathlessness, do not use a sauna. These conditions can increase the risk of complications.

How to use a sauna more safely

If your doctor says sauna use is okay, keep sessions short and mild. Start with five to ten minutes and leave straight away if you feel light-headed, overheated, or uncomfortable.

Drink water before and after, but avoid alcohol. Do not use a sauna alone if you have a heart condition, especially if you are unsure how your body will react.

Warning signs to stop immediately

Stop using the sauna if you develop chest pain, severe breathlessness, nausea, faintness, or an unusually fast or irregular heartbeat. These may be signs that your heart is under too much stress.

If symptoms do not quickly settle, seek urgent medical help. In the UK, call 999 if you think you may be having a heart attack or another emergency.

Getting personal medical advice

The safest approach is to ask your GP, practice nurse, or heart specialist before using a sauna. They can consider your diagnosis, medicines, blood pressure, and overall fitness.

This is particularly important if you take tablets that affect blood pressure or fluid balance. A short discussion with a healthcare professional can help you decide whether sauna use is safe and how to do it sensibly.
