How to protect your heart during the winter

Why can winter affect your heart?

According to the British Heart Foundation (BHF) your chance of having a heart attack or stroke increases during the winter months.

If you've previously had a crise cardiaque, you're also more susceptible if you contract la grippe - the likelihood of which increases in winter.

Dr Helen Flaherty, registered nutritionist and former Head of Health Promotion and Education, Heart Research UK says: "As well as higher rates of flu in the colder months, there are other factors that contribute to the rise in winter heart attacks.

"As temperatures drop, your blood vessels contract and your heart needs to work harder to keep you warm, leading to increased heart rate and pression artérielle. Cold temperatures can cause changes in the formation of blood, making your chance of blood clots more likely, which can trigger a crise cardiaque ou AVC."

She adds that the winter months can also induce lifestyle changes, such as a decrease in physical activity, a less healthy diet, increased alcohol intake and fumer - particularly around the festive period. Increased emotional niveaux de stress during this time is also believed to impact the rise in heart attack rates.

Heat your home appropriately

You can reduce the effect of cold weather by keeping your home heated to 18°C or higher, and by wrapping up well when you head outdoors.

"When it's very cold, snowy or icy, it may be better to stay indoors as much as you can," says Flaherty.

Ruth Goss, Senior Cardiac Nurse, The British Heart Foundation adds: "When you're indoors, wear warm socks and slippers to keep your feet cosy. You could also wrap up in a blanket, use a hot water bottle, or an electric blanket."

Wrap up when outside

It's important to wrap up in warm layers of clothing when going outside in the cold.

Goss says: "Wearing a few thin layers can keep you warmer than one thick layer. Putting on a hat, scarf and gloves will help to maintain your core heat.

"If you have angine de poitrine, you could wear a scarf wrapped loosely around your mouth and nose, or wear a face mask, so you breathe in warmer air. This may help to improve any symptoms you might get in colder weather. However, if they persist or worsen, contact your doctor or call 999."

Stay active

Exercising can help prevent la prise de poids, which can put strain on your body, heart and immune system, and may make it less effective at fighting infections. It also increases your odds of complications if you catch the la grippe ou COVID-19.

Flaherty says: "Feeling motivated to stay active during the cold, dark winter months can be challenging, particularly if you tend to exercise outdoors. You might want to look at indoor activities, such as badminton, dancing, yoga, gym classes, or online faire de l'exercice classes at home."

Regular exercise - whether that's indoors or outdoors - is important for keeping your heart healthy.

Goss explains: "This can help to reduce l'hypertension artérielle, and lower your chance of having a heart attack or AVC. However, if you have a heart condition or are elderly, you might want to stay active indoors during the colder months. There are plenty of activities you can do indoors, from circuit training to chair-based strength exercises - aim to work muscles all over the body."

Get the flu vaccine

Getting your vaccin contre la grippe is vital if you are older, or have a heart and circulatory condition.

Goss says: "It will help to reduce your likelihood of catching flu, which can exacerbate conditions such as coronary heart disease and une insuffisance cardiaque."

If you're not eligible for a free vaccine, you can choose to pay for the jab, or check if your employer may be offering it.

Mangez bien

It's important to have regular hot repas and drinks to give your body the energy it needs to keep you warm. During winter, it can be tempting to binge on less healthy nourriture réconfortante, but hearty meals can be good for you too.

Flaherty says: "Plan your meals in advance and try to include lots of fruit and vegetables, oats and wholegrain foods, oily fish, unsalted nuts, and seeds. Beans are also good for your health, as well as low-fat dairy products, and lean meats or vegetarian and vegan alternatives."

Be careful with alcohol

It can be easy to overindulge in d'alcool during the festive period. However, drinking too much can increase your chance of developing high blood pressure and coronary heart disease.

"Keep an eye on your d'alcool intake and try to stick to the guidelines of no more than 14 units, spread over three or more days each week," says Flaherty. "Look for drinks with a lower alcohol content, or alcohol-free alternatives - such as reduced-calorie soft drinks or mocktails and herbal teas."

If you are a smoker - or occasional smoker - you may find that you fument more during the festive period.

Flaherty warns: "Smoking can damage your cœur and blood vessels, which increases your likelihood of having a crise cardiaque. Quitting smoking can be difficult, but it is an important step for reducing your chance of developing heart disease.

"Quitting fumer requires a huge amount of willpower, and getting support from your doctor, friends, family or local support group can really help."

Rest if you become unwell

If you feel like you're developing a toux ou températures froides, try to rest and drink plenty of fluids.

Goss says: "If you already have a heart condition, it's important you get advice from your pharmacist before taking over-the-counter remedies, as some may not be safe to take with your regular medicine."

If you are 65 or over - or in one of the other at-risk groups - seek medical help from your doctor, pharmacy or NHS 111 as soon as you feel unwell.
