10 tips for managing diabetes this winter

When winter rolls in, your daily routine can change and that can affect how you’re managing diabetes. According to an article written by Amy Campbell, a registered dietician and diabetes educator, as the temperature drops, blood sugars may rise. That's because when snow, ice and cold weather keep you inside, you may exercise less and eat more. Remember, everything is manageable, it is just a matter of adapting and having a few hacks up your sleeve. 

The good news? A few small adjustments can make a big difference. Here are 10 practical, easy-to-follow tips to help you stay on track this winter.

1. Keep moving (even when it’s cold)

We get it, winter is perfect for cuddle up on the couch, enjoying a good book, or watching TV by the fire. But staying active is still really important to keep your blood glucose levels under control and relax your mind.
You don’t have to head out into the cold. You can try home workouts, join a gym, or go for indoor walks. The key is consistency, not perfection.

2. Beat the winter blues

The wet and cold seasons can be stressful and that coupled with shorter days can often affect your mood. Keep up your exercise, healthy eating and keeping busy with the things that you enjoy to keep your spirits up. If you're struggling to stay positive this winter, talk with your friends or your doctor for support.

3. Keep an eye on the scale 

Although it is cold outside, it is important to take extra precautions to make sure you keep up your health and exercise. Extra snacking, comforting meals and lack of physical exercise can lead to weight gain. Come up with a plan to make sure you stay healthy this winter. You don’t have to give up your favourites, just keep an eye on balance and portion sizes.

4. Take care of yourself even if you get sick

Colds and flu are more common in winter, and when you’re unwell, managing diabetes can sometimes feel like less of a priority and blood glucose levels may fluctuate.
If you do get sick, make sure to check your blood glucose levels more frequently and have a sick-day plan.

5. Having high blood sugar can trick your body into thinking it is warm

Even when you are exposed to cold weather, sometimes having high blood sugar can make you feel warm. This can lead to complications therefore following the tips, that's why checking your blood glucose levels regularly are so important to ensure you remain at the right levels, rather than relying on how you feel.

6. Keep your diabetes devices and insulin out of the cold

Just like how extreme heat affects your insulin, extreme cold can affect it just as much. Insulin can freeze when temperatures drop near to below 0ºC. It is recommended that you avoid exposing your insulin pump and glucose monitor to weather below 0ºC. If you are outside in the cold weather, wear your pump close to your body and cover it with warm clothing. Cold weather can break down insulin and cause it to lose its effectiveness, so make sure your blood glucose meter is protected in a wallet or case.

7. Protect your immune system

As winter is cold and flu season it can be a stressful time and being sick and stressed could lead to differing blood glucose levels. Stay prepared: we recommend talking to your doctor to check whether you should be getting your annual flu shot to protect yourself against the flu. Make sure you keep practicing personal hygiene by washing your hands and using hand sanitiser and stay hydrated.

8. Test blood glucose levels regularly

Dramatic changes in temperature may affect your blood glucose levels. As we transition into cooler seasons it is important to pay close attention to your CGM trend. A change in season may mean a shift in activities or schedule so blood glucose levels can fluctuate. If you notice a shift in levels, talk with your healthcare team about adjusting your basal rate or turning on a basal pattern to help keep your insulin stable.

9. Keep your hands warm

Having cold hands can make testing your blood glucose levels more difficult as the blood tends to drift away from your fingers. We recommend wearing gloves when you are outside as it is one of the easiest ways to keep your hands warm during the cold months. Some gloves/mittens have features that allow you to only expose one finger which is particularly useful for testing in colder months. If your hands are cold, warm them up before you test for more accurate results. 

10. Don’t forget your feet

Winter air can dry out and crack your skin, especially on your feet, which could lead to wounds. Make sure to protect your feet with the necessary footwear.
