In cold weather, your insulin may be absorbed more slowly at first, but it can then be absorbed suddenly when you warm up later in the day. This can increase the risk of hypos (low blood sugar). Additionally, shivering in the cold uses up more energy, which can also lead to hypos. To avoid this, it’s important to wear layers in cold climates, as they will help keep you warm and allow you to adjust your clothing as your body temperature changes.

Why Hypos Are More Dangerous in Cold Conditions

Hypos are more dangerous in cold conditions because they interfere with your body’s ability to stay warm, increasing the risk of hypothermia. To avoid this, it’s crucial to monitor your blood sugar levels more frequently in cold weather and be prepared to adjust your insulin dose or diet as needed. Carry hypo treatments like glucose tablets or snacks with you at all times.

Blood Glucose Meters and Cold Conditions

Cold temperatures can affect the accuracy of blood glucose meters. If you’re travelling to a destination with extreme cold, check the manufacturer’s guidelines for the temperature ranges at which your meter will function accurately. Keep your meter as close to room temperature as possible, ideally in an inner pocket or a warm pouch.

Preventing Frostbite and Neuropathy

For those with neuropathy or poor circulation, it’s particularly important to guard against frostbite, as the numbness in your feet can prevent you from feeling the cold. Make sure to check your feet regularly and take extra care in cold climates. Wearing extra layers and spare socks will help protect against the cold and reduce the risk of frostbite.

By following these precautions, you can manage your diabetes effectively even in cold weather, reducing the risk of complications such as hypos and frostbite.
