Here's why your blood pressure may rise at this time of year and what you can do about it.

You may expect your heating bill to go up when temperatures drop, but did you know your blood pressure may rise, too? Even if your blood pressure is usually well controlled, you might notice higher readings during the winter months. Cold weather is partly to blame, but changes in your daily habits may also play a role.

Why Blood Pressure Rises in Winter

Blood pressure measures the force of blood pushing against the walls of your arteries. Several things can cause that pressure to increase at this time of year, including:

• Cold temperatures. When you're exposed to cold air, blood vessels narrow to help your body hold on to heat. This makes it harder for blood to flow and causes your blood pressure to rise. Even brief exposure to very cold weather can affect your readings.
• Less physical activity. Shorter days and chilly temperatures may keep you indoors more often. If you're moving less than usual, your blood pressure may creep up. Regular exercise helps keep your heart and blood vessels healthy.
• Changes in eating habits. Winter comfort foods, holiday meals and packaged foods often contain more sodium than you realize. Too much sodium can raise blood pressure, especially if you're sensitive to salt.
• Weight gain. It's easy to put on a few extra pounds when you're less active and eating more calorie-rich foods. Even modest weight gain can affect your blood pressure.
• Seasonal stress. Holiday obligations, financial worries and changes in routine can add stress during the winter. Stress can temporarily raise blood pressure and may lead to habits that may also increase your numbers.

How to Keep Your Blood Pressure Under Control

Here are a few ways to help prevent your blood pressure from climbing at this time of year:

• Stay active. Aim for at least 150 minutes of moderate exercise each week. Walk indoors, try an exercise video or visit a gym when the weather isn't cooperating.
• Dress warmly. Wear layers when heading outdoors and cover exposed skin. Keeping your body warm may help limit the effect cold temperatures have on your blood vessels.
• Watch your sodium intake. Choose fresh foods more often and check nutrition labels on soups, frozen meals and other packaged foods. Season meals with herbs and spices instead of extra salt.
• Manage stress. Make time for activities that help you relax, whether that's reading, listening to music or spending time with loved ones.
• Check your blood pressure regularly. If you have high blood pressure, monitor your readings at home as recommended by your doctor. Take measurements at the same time each day and keep a record to share at appointments.

Blood pressure changes with the seasons aren't unusual, but consistently high readings shouldn't be ignored. If your numbers are higher than normal, talk to your doctor. You may need changes to your treatment plan but never adjust blood pressure medication on your own.
