Fall is here, and flu season is just around the corner. Getting sick not only feels miserable but can also make managing your blood sugar more challenging. So how can you stay healthy this flu season? You’ve probably heard about supplements like echinacea, vitamin C, and ginger shots but which approaches actually work? Here are some evidence-based ways to help reduce your risk of getting sick this fall and winter.
1. Get enough sleep
Most adults need between 7-9 hours of sleep but it’s hard to get! Typically, sleep is prioritized last when it comes to our busy lifestyle and may be interrupted to deal with high or low blood sugars or a trip to the washroom. Focus on what you can control, which is doing your best to stick to a bedtime schedule, avoiding screens, caffeine and alcohol close to bedtime and limiting lights from electronics (use a sleep mask if necessary).
2. Eat a healthy diet
There is no one food that will “boost” your immune system. The goal here is to aim for a well-balanced diet with vegetables, fruits, whole grains, healthy fats (like nuts and seeds) and lean proteins (like chicken and fish) while limiting high sugar, fat and ultra processed items.
3. Wash your hands!
This one seems obvious but every time before you eat or touch your face, wash your hands. If you are not able to wash your hands in the moment, then use hand sanitizer.
4. Exercise regularly
Although excessive exercise can suppress the immune system, regular exercise can help by circulating immune cells around the body. Exercise also reduces inflammation. When you are sick however, it’s best to limit vigorous exercise and let your body rest and heal.
5. Get vaccinated
Vaccines work by helping your immune system fight a specific pathogen by exposing it to an inactive or weakened form. Flu and Covid vaccines are updated annually because these viruses constantly change or “mutate.” Speak to your healthcare team to find out what vaccines are recommended for you.
6. Limit or avoid alcohol
Alcohol, even small amounts, can weaken the immune system which increases our susceptibility to getting sick. Alcohol also causes poor sleep quality and can limit your ability to make healthy lifestyle choices. Health Canada has changed their recommendations regarding alcohol consumption for the general population:
- If one does choose to drink, limit consumption as much as possible.
- The new low-risk threshold is no more than 2 standard drinks per week.
- Also, per occasion, do not exceed 2 standard drinks.

7. Manage blood sugars
This may come as no surprise, but consistently high blood glucose levels can weaken your immune system. Elevated glucose makes it harder for white blood cells to move effectively and fight off bacteria and viruses, which means your body may have a tougher time healing wounds or fighting infections. Even a mild illness can raise your blood sugar further, creating a cycle that makes recovery slower.
