Experts suggest that increasing daily vitamin D intake is the best way to raise your body's resistance to the flu this winter. Vitamin D is naturally acquired through exposure of the skin to sunlight and, to a lesser extent, from food.
Not surprisingly, studies show that 97 percent of Canadians are deficient in vitamin D during the winter months. Low levels of vitamin D will significantly impair your immune response resulting in a higher susceptibility to viruses such as H1N1, risk of complications and recovery time.
Other factors which may weaken your immune system include:
- Lack of sufficient or quality sleep
- Excess refined sugar in the diet
- Poor stress management
Strengthening your immune system is your best defence against flu viruses. Ask your doctor to check your vitamin D levels with a simple blood test and speak to Aviva about supplementation options and choosing the right one for you.
