Perhaps the number one preventative thing that we can all do is get vaccinated for seasonal influenza. Good hand hygiene is imperative as another preventative measure against the spread of illness. Teach children to cover their cough or sneeze and to wash their hands after they touch their noses or sneeze.
Try to promote a healthy winter diet. Many of us complain about putting on the calories during the winter months but eating food items rich in Vitamin C like citrus fruits, tomatoes, melons and leafy greens are a great way to maintain a healthy immune system while limiting calorie intake. Also, keep well hydrated as this will help to reduce the susceptibility to a cold or the flu. Lastly, shake off winter laziness and avoid seasonal depression by encouraging regular exercise during the winter. Activities such as ice skating, snowboarding, skiing and tobogganing are all fun and healthy!
