Protecting Your Heart Through Winter in Brampton

Brampton winters have their own rhythm. Driveways disappear under overnight snow, the drive along Hurontario Street slows to a crawl, and many of us spend more time indoors than we would like. For most people, winter is simply inconvenient. For people living with high blood pressure, heart disease or other circulation problems, it can also bring real risks that are worth planning for.

Cold weather affects the cardiovascular system in ways that are easy to overlook. Blood vessels narrow, blood pressure can rise, and sudden bursts of heavy effort, like clearing a driveway after a storm, can place a heavy demand on the heart. Shorter days and holiday leftovers can also nudge routines off track.

This post looks at what winter does to the heart and practical steps that can help you get through the season safely. If you have specific questions about your own medications or conditions, the pharmacists at Pharmasave BramCentre, 14 - 7910 Hurontario Street, Brampton are happy to talk them through.

How cold air affects your blood vessels

When you step outside into cold air, your body works to keep its core warm. One way it does this is by narrowing blood vessels in the skin and extremities, which reduces heat loss. That narrowing increases resistance in the circulation, and blood pressure can rise as a result.

For a healthy person, this is usually a temporary adjustment. For someone whose heart is already working harder because of narrowed coronary arteries, heart failure or uncontrolled blood pressure, the extra demand can be more significant. Some people with angina notice that chest discomfort comes on more easily in cold weather, especially when walking into a wind.

People who monitor their blood pressure at home sometimes see slightly higher readings during the colder months. If you notice a consistent change, share your log with your healthcare provider rather than adjusting medications on your own.

The truth about snow shovelling

Shovelling snow is one of the most physically demanding things many people do all year. It combines heavy lifting, straining, bending and cold exposure, often first thing in the morning and often by people who have been relatively inactive in the weeks before. The Heart and Stroke Foundation has long cautioned that shovelling can be hard on the heart, particularly for people with known heart disease or several risk factors.

If you have heart disease, high blood pressure, diabetes, or have been told to limit exertion, ask your doctor whether you should shovel at all. Arranging help from a neighbour, a family member or a snow-clearing service may be the safer option.

If you do shovel, consider these precautions:

• Warm up indoors with some gentle movement first.
• Push snow rather than lifting it when you can.
• Lift small amounts, bending at the knees rather than the back.
• Take frequent breaks, and go inside to warm up.
• Avoid shovelling right after a heavy meal.
• Avoid smoking and limit caffeine before shovelling, as both can raise heart rate and blood pressure.
• Stop immediately if you feel chest discomfort, unusual shortness of breath, dizziness or pain in the arm, jaw, neck or back.

If those symptoms do not go away quickly with rest, call 9-1-1.

Warning signs that mean stop and get help

Winter exertion is a time when many people first notice that something is wrong with their heart. The trouble is that early warning signs can be easy to explain away. Breathlessness gets blamed on the cold air, chest tightness on a heavy coat, and fatigue on a bad night’s sleep.

Signs that should make you stop what you are doing include:

• Chest discomfort, which may feel like pressure, squeezing, heaviness or burning rather than sharp pain
• Discomfort that spreads to the arm, shoulder, neck, jaw or back
• Shortness of breath that is out of proportion to the effort
• Sweating, nausea or light-headedness
• A sense that something is seriously wrong

Women, older adults and people with diabetes may have less typical symptoms, such as unusual fatigue, indigestion-like discomfort or breathlessness without chest pain. If symptoms do not settle promptly with rest, call 9-1-1. If your doctor has prescribed nitroglycerin for angina, use it as you have been instructed, and do not delay calling for help if symptoms continue.

It is also worth paying attention to milder patterns. If you find that the same walk to the bus stop or the same amount of shovelling is making you more breathless than it did last winter, mention it to your doctor. A gradual change in exercise tolerance can be an important clue, and it is far better discussed at a planned appointment than discovered in an emergency.

Dress for your circulation, not just for style

Layering helps keep the body warm without overheating. A hat matters, as do gloves or mittens and warm socks. For people with poor circulation in the legs or feet, or with diabetes, keeping the feet warm and dry is especially important; cold, numb toes can make injuries harder to notice.

Covering your mouth and nose with a scarf can warm the air you breathe, which some people with angina find more comfortable. Try not to rush from a warm car into the cold and straight into exertion. A slower transition gives your body time to adjust.

Staying active when it is dark by five

Regular physical activity supports heart health, but winter makes it harder to stay consistent. Icy sidewalks, early sunsets and cold mornings can turn daily walks into weekly ones.

Some indoor options many Brampton residents use include:

• Walking laps at an indoor shopping centre during quieter hours
• Community centre fitness programs and pools
• Home exercise routines, from simple marching in place to video-guided workouts
• Stair climbing at home, if your doctor has said it is safe for you

Canada’s physical activity recommendations, available through the Canadian 24-Hour Movement Guidelines, offer a helpful reference. If you have a heart condition, check with your healthcare provider about what level of activity is appropriate before starting something new.

Winter illnesses and your heart medications

Colds, flu and other winter infections add stress to the body, and the products people reach for to feel better are not always friendly to the heart. Some decongestants can raise blood pressure and heart rate. Some pain relievers can raise blood pressure, affect the kidneys or interact with blood thinners.

Before choosing a cold or flu product, tell the pharmacist which heart or blood pressure medications you take. Ask whether a particular product is suitable for you. The pharmacy can also talk with you about minor ailment assessments for certain conditions within a pharmacist’s scope, and about the flu shot, which many people with chronic heart conditions are encouraged to consider.

Dehydration during illness, vomiting or diarrhea can also affect some heart and blood pressure medications. If you are sick and unable to keep fluids down, ask your pharmacist or prescriber whether any of your usual medications need special attention.

Holiday leftovers and the January reset

Winter in Brampton often includes a stretch of celebrations: Christmas, New Year’s, Lohri and other cultural gatherings, plus family visits that stretch across weeks. Rich foods, sweets, salty snacks and late nights tend to come with them.

Many people notice their blood pressure creeping up after the holidays, often linked to extra salt, alcohol, less sleep and less activity. January is a natural time to gently return to your usual routine. You do not need a dramatic plan. Getting back to regular meals, reducing salty snacks, resuming walks and prioritising sleep can help.

Do not let weather interrupt your prescriptions

Snowstorms and icy roads can make it hard to get to the pharmacy. Running out of a heart or blood pressure medication because the roads were bad is a situation worth avoiding.

A few ways to stay ahead:

1. Check your supply before a forecasted storm or long weekend.
2. Use the prescription refill service to request refills a few days early.
3. Ask about home delivery if winter travel is difficult, and confirm whether your address is within the delivery area.
4. Keep an updated medication list at home in case you need care unexpectedly.

If you are a caregiver for an older relative, check their supply too. Many seniors avoid going out in icy weather, which is sensible, but it can lead to gaps in medication.

A winter heart checklist

Before the next cold snap, consider whether you have:

• A plan for snow clearing that does not put your heart at risk
• Warm layers, including hat, gloves and warm socks
• An indoor activity option for cold or icy days
• At least a week’s supply of essential medications
• An up-to-date medication list
• Knowledge of heart attack and stroke warning signs, shared with your household
