Why do we get sicker in the Winter?

Why are we more susceptible to cold and flu during a specific season?

Much like my last post, it’s a combination of susceptibility and exposure, simply put: both are higher in the Winter months. Let’s break down what factors come into play.

1. Exposure: Virus’ flourish in cold, dry weather.

We now know that the flu virus in particular has a nice, protective lipid membrane around it, and of course that lipid freezes in cold temperatures. This is almost like a nice preservation method for the virus so that it can journey its way from person to person. When exposed to a temperature of 15*C or warmer, that layer melts and the virus gets to work. (1)

To add insult to injury, dry air is the ideal climate for influenza to exist in. (2)

What to do about it? Reduce your susceptibility and decrease exposure!

  • Invest in a humidifier for inside your house to keep humidity up, especially if you’re running your heat often (and be sure to keep it clean).

  • Keep surfaces clean, wash your hands.

2. Exposure: We’re inside more.

From the house, to the car/bus, to the office (all day) to the car/bus, to home, to maybe a social event here or there (still indoors) – our time inside increases dramatically as the air cools down and so does the proximity to our fellow germ hosts.

I don’t want to bog this post down with too many nasty facts about how fast colds/flu spread in offices, so click if you dare – but know that it’s quick and can be thwarted by good hygiene.

More time indoors = more time in close quarters = more exposure to illness.

What to do about it?

  • Get outside! Break up the indoor routine.

  • Keep surfaces clean, wash your hands!

  • Reduce your susceptibility because you can’t avoid exposure.

  • If you’re sick, stay home. We’re all responsible!

3. Susceptibility: Low vitamin D levels

Vitamin D has proved time and time again that it is crucial for immune function (3) and here in Canada, we physically cannot produce enough in the summer months because the sun is simply too low.

What to do about it?

  • Supplement with Vitamin D3 and test your levels if you can.

  • Get outside, especially on sunny days. Even if you’re not producing max Vitamin D – it feels good and your body needs it!

4. Susceptibility: Winter is hard in Canada

Winter is hard, especially in Canada – and quite frankly when it’s -40 and we’re just trying to survive, we take poor care of ourselves. We simply need to be more mindful of our health in the winter months.

What to do about it?

  • Manage stress; September seems to “gear up” for a lot of people – and so does stress. Be mindful of what you’re going through, what your kids are going through with back to school – slow down, focus on your basic needs, get exercise, take a vacation or a staycation.

  • Manage chronic illness: Seasonal affective disorder, lack of vitamin D, the cold, change in foods – all tend to exasperate chronic illness, which can put extra stress on your system and lower immunity. This is a great time to see a homeopath to get your mental health, chronic pain, and other symptoms under control.

  • Get outside, keep up fresh food intake, take Vitamin D, increase vitamin C intake.
