How Cold Weather Can Affect Heart Rhythm Disorders
As the seasons shift and temperatures drop, it’s common to notice changes in how your body feels, from stiff joints and dry skin to lower energy levels. But for people with heart rhythm disorders, cold weather can affect more than just comfort. It may also influence how the heart functions.
At the Oklahoma Heart Hospital’s Heart Rhythm Institute, we believe in helping patients understand how everyday factors, including the weather, can impact their condition. If you have atrial fibrillation (AFib) or another arrhythmia, here’s what you should know about navigating colder months.
Can cold weather trigger arrhythmia symptoms?
Yes, for some people, cold temperatures can increase the likelihood of arrhythmia symptoms or episodes. Exposure to cold causes blood vessels to constrict, which raises blood pressure and makes the heart work harder. This added strain can increase the risk of irregular rhythms, especially for those already living with a heart condition.
Winter months may also bring other challenges. Increased holiday stress, changes in physical activity, and even dehydration, which is more common in cold weather due to fewer thirst cues, can all contribute to symptoms.
Respiratory illnesses like colds and flu and medications used to treat them may also put added strain on the heart. In addition, reduced daylight can affect mood and overall well-being for some, making it difficult to remain consistent with self-care routines.
Who is most at risk?
People with existing heart rhythm disorders, particularly AFib, are more likely to notice seasonal changes in how they feel. You’re also at greater risk if you:
- Have high blood pressure or heart failure
- Take medications that affect hydration or heart rate
- Are sensitive to temperature extremes
- Tend to exercise outdoors during winter
Even otherwise manageable arrhythmias can be harder to control when the body is under physical stress, including cold exposure.
How to protect your heart in colder months
You can’t control the weather, but you can take steps to minimize your risk:
- Dress in layers and keep your core warm when outdoors.
- Warm up slowly before physical activity to avoid any sudden shock to your system.
- Stay hydrated, even if you don’t feel thirsty.
- Avoid overexertion during winter tasks, such as shoveling snow or carrying heavy loads.
- Talk with your cardiologist if you notice new symptoms or need to adjust your medications.
Cold weather isn’t dangerous for everyone, but it’s worth paying attention to how your body reacts, especially if you’ve been diagnosed with a heart rhythm disorder.
