Why Winter Brings More Colds & Flus (and How to Stay Well Naturally)

As soon as the chill sets in and the nights get longer, it often feels like the season of sniffles begins. Winter and colds seem to go hand in hand — but why is that? And more importantly, what can we do to support our bodies through the colder months?

Why We Tend to Get Sick in Winter

It turns out it’s not the cold air itself that makes us sick, but the perfect storm of conditions that come with the season:

• Viruses thrive in cooler, drier air – cold temperatures and lower humidity allow them to survive and spread more easily.

• More time indoors – when we gather inside with less ventilation, it’s easier for germs to pass from person to person.

• Dry airways – cold air can dry out the mucous membranes in the nose and throat, making it harder for the body to trap and flush out viruses.

• Less sunlight – shorter days mean less natural vitamin D, which plays a role in overall wellness.

So while winter itself doesn’t cause illness, it creates conditions where viruses can spread more easily, and our bodies may not be functioning at their best.

The Gut–Winter Connection

Approximately 70–80% of the immune system is located in the gut, which is the body's largest immune organ. This is due to the large population of immune cells and diverse microbes, collectively known as the gut microbiome that are housed there and it highlights just how closely connected gut health and overall wellbeing are.

The trillions of microbes in your digestive system — your gut microbiome — are influenced by what you eat and drink every day. When this community is balanced, it helps your body stay resilient through seasonal challenges.

Supporting gut health is one reason why many people include fermented foods like sauerkraut, kimchi, or a high-quality probiotic superfood in their winter routine.

8 Simple Tips for Staying Well This Winter

There’s no single magic bullet for avoiding winter bugs, but supporting your body with healthy lifestyle habits can make a real difference:

1. Eat nutrient-rich foods – Seasonal fruits, leafy greens, and wholefoods provide fibre and nutrients that feed beneficial gut bacteria.

2. Include fermented foods & probiotics – Sauerkraut, kimchi, kombucha, or Immunity Fuel can be a simple daily addition.

3. Stay hydrated – Water, herbal teas, and nourishing soups help counteract dry winter air.

4. Get some winter sunshine – Even short bursts support vitamin D levels. Foods like oily fish, eggs, and mushrooms are natural options.

5. Keep moving – Gentle exercise like walking helps circulation and supports overall wellbeing.

6. Sleep well – Quality rest is when the body repairs and recovers.

7. Manage stress – Relaxation, meditation, or reading can help reduce the impact of stress on overall wellness.

8. Explore traditional herbs – Plants such as ginger, garlic, and elderberry have been used in winter wellness routines for centuries.

How Probiotics Support Your Routine

Probiotics — the beneficial bacteria found in fermented foods and supplements — help maintain gut microbiome balance. Supporting gut health in this way is especially valuable during the colder months when our bodies face extra seasonal challenges.
