    Vitamin D Levels might explain colds

    Vitamin D Levels might explain colds

    Low Vitamin D levels may explain increased incidence of colds and flus. Vitamin D levels are at their lowest at the end of winter and low levels are associated with increased risk of infections.

    Now is the time that Vitamin D levels are at their lowest. We have known for a long time that Vitamin D deficiency is associated with  low bone mineral density, but evidence is becoming more clear that it is also linked to many other conditions.

    One of them is impaired immunity and increased risk of colds and flus. This may be one of the reasons that we get more colds in the winter: less time in the sun means lower vitamin D levels. We need to expose our arms and legs to the sun for 30 minutes in a Sydney winter (not between the hours of 10am and 2pm) in order to convert enough vitamin D to its active form. Vitamin D has been shown in clinical trials to stimulate immune cells in the respiratory tract, thus reducing the incidence of respiratory infections.
