Do you find yourself catching colds more easily or feeling run down as the weather changes?
Our immune systems naturally become less responsive with age — and when combined with lower sunlight, colder temperatures and more time indoors, it can leave you feeling below par.
The good news? With the right nutrients and daily habits, you can stay strong all season long.
Why Immunity Weakens in Colder Months
- Less sunlight – Lower vitamin D levels make it harder for your body to activate immune defences.
- More indoor time – Viruses spread faster in closed spaces during autumn and winter.
- Colder temperatures – Can affect circulation and energy, leaving you more vulnerable.
- Age-related slowdown – White blood cells respond more slowly over time.
- Poor sleep or stress – Both can suppress your immune response.
Daily Habits That Strengthen Immunity
- Stay active – Light exercise like walking boosts circulation and immune function.
- Sleep well – Aim for seven to eight hours of consistent rest.
- Eat colourfully – Fruit, vegetables and herbs provide protective antioxidants.
- Stay hydrated – Even mild dehydration weakens your defences.
- Get daylight – Brief daily sunlight helps maintain vitamin D levels and mood.
Key Nutrients for Immune Support
- Vitamin D – Essential for immune cell activation; most adults in the UK need extra during winter.
- Vitamin C – Helps protect cells from oxidative stress and supports tissue repair.
- Zinc – Vital for the development of immune cells and healing processes.
- Probiotics – Support gut balance, where most immune activity begins.
- Elderberry & Turmeric – Botanicals known for natural antioxidant and anti-inflammatory benefits.
Simple Tips to Stay Healthy This Season
- Add a brisk 15-minute walk outdoors to your day.
- Include garlic, berries and leafy greens in meals.
- Wash hands often and avoid touching your face in public.
- Take supplements consistently — not just when you feel unwell.
