The holiday season is a time for love, joy and fellowship with loved ones. We often indulge in our favorite holiday meals and snacks as we enjoy much-needed time off or rest from work. While the holidays are usually full of wonderful things, they can also be full of stress and even carry a greater risk for heart attacks.

Keep reading to learn more about the risk of heart attacks during the holiday season, including why they’re more likely, prevention tips and how to respond to a heart attack.

Why Do Heart Attacks Increase During the Holidays?

According to the American Heart Association, heart attacks are more likely during the holiday season, specifically the last week of December, than any other time of year. But why is this the case? There are several reasons why heart attacks are more likely to occur during the holidays, including:

Colder weather

Typically, the holidays are accompanied by colder weather, which can cause your blood vessels to constrict, leading to higher blood pressure and a greater workload for your heart.

Delayed medical care

Unfortunately, many disregard heart attack symptoms during the holiday season because they chalk it up to indigestion, overeating or stress.

Excessive alcohol consumption

It’s typical for alcohol consumption to be higher during the holidays as people gather and celebrate. But increased alcohol consumption can lead to dehydration, irregular heart rhythms and added strain to the heart muscles.

Increased stress levels

Whether you’re running to a million stores to gather the supplies you need for Christmas dinner, checking off every gift on your family’s list or navigating difficult family dynamics, stress levels are often elevated during this season. Elevated stress produces a hormone called cortisol that can raise your blood pressure and increase strain on the heart.

Overindulgence

While we’re full of joy during this season, we’re probably full of food, too. It can be easy to overeat during the holidays, and these holiday foods typically have a higher content of fat, cholesterol and sugar, which can raise your blood pressure and lead to heart risk factors, especially for those with preexisting conditions. But with a few tweaks here and there, you can enjoy heart-healthy alternatives without sacrificing taste to better care for your loved ones’ hearts.

There’s also a phenomenon known as holiday heart syndrome. This term is used to describe irregular heart rhythms, or atrial fibrillation (AFib), brought on by excessive consumption of alcohol. The elevated levels of alcohol in your system disrupt the heart's normal electrical signals and can lead to heart attacks and other heart complications. It’s best to limit alcohol consumption, especially around the holidays, to keep your heart beating strong. Consider trying some of these alcohol-free holiday beverages for your festivities.

Symptoms of Heart Attacks

It’s essential to recognize the common signs of a heart attack so you know when to seek medical attention. Common heart attack symptoms include:

Chest pain or discomfort — feels like the chest is tight or being squeezed, normally in the center or left side of the chest, lasts between three and five minutes, can come and go
Extreme fatigue
Diaphoresis (breaking into a cold sweat)
Indigestion
Irregular heartbeat
Lightheadedness
Nausea
Pain in other areas of the upper body, including the arms, back, jaw, shoulders and neck
Shortness of breath
Vomiting

If you or a loved one experiences any of these symptoms, call 911 or visit your nearest ER.

How to Respond to a Heart Attack

Responding to a heart attack promptly can make all the difference for your recovery. If you suspect that you or a loved one is having a heart attack, call 911 immediately. As you wait for help to come, take the following steps:

Take aspirin
Take prescribed nitroglycerin if you have it
Loosen your clothing
Lie down

If you’re helping someone experiencing a heart attack, look for a nearby automated external defibrillator (AED) in case they lose consciousness, and always be prepared to perform CPR. We hope you and your loved ones never experience a heart attack, but if you do, we want you to be prepared.

Preventing Heart Attacks

While not all heart attacks can be avoided, there are certainly lifestyle changes you can make to reduce the likelihood of experiencing one. To prevent a heart attack, we recommend:

Finding ways to manage your stress
Getting at least 30 minutes of moderate exercise five days a week
Keeping your diet low in saturated fats and cholesterol
Maintaining a healthy weight
Quitting smoking
Regularly checking your blood pressure

When it comes to matters of the heart, prevention is the best medicine.
