The colder months can feel cosy and comforting, but they also come with an increase in colds, flu, and general seasonal fatigue. Despite the Christmas festivities, this stretch is often where people feel most run-down - which makes maintaining healthy winter habits more important than ever.

Focusing on healthy winter food as well as movement, sleep, and stress management creates a foundation that helps your immune system stay resilient. The good news? Most of these habits are simple, gentle, and easy to weave into your everyday routine.

Eat for Wellness: Nourishing With Healthy Winter Food

What you eat is one of the most powerful tools for protecting your health through the colder months. Vitamins, minerals, antioxidants, and fibre all help your immune system function optimally - and this time of year offers plenty of opportunities for healthy winter dishes and comfort meals that still feel hearty and nourishing.

1. Build balanced, colourful plates

Seasonal produce like apples, pears, clementines, cauliflower, parsnips, Brussels sprouts, and cabbage can be transformed into healthy and hearty meals or healthy winter dinners that warm you from the inside out.

To boost your daily fruit and veggie intake, try:

Blending seasonal veg into healthy winter recipes like soups
Adding legumes to stews for extra fibre and protein
Topping your breakfast with fresh fruit for a morning vitamin boost

If cooking feels overwhelming at this time of year, a meal prep service can help you stay consistent with comfort meals for winter that are balanced, delicious, and ready when you are.

Healthy Winter Habits to Keep You Feeling Your Best

2. Keep moving - even when it's cold out

It can be tempting to curl up indoors until spring arrives, but staying active plays a big role in immune health. Research (You, 2023) consistently shows that regular physical activity is linked to a lower chance of developing upper respiratory infections like the common cold or flu. Even short bouts of movement - think a brisk 20-minute walk, a light home workout, or yoga - can help support your body’s natural defences.

If motivation is tough during darker days, try:

Walking with a friend
Enjoying a podcast while stretching
Choosing gentle, feel-good movement rather than intense workouts

Small efforts count, and they can make winter feel much more manageable.

Sleep and Stress: Two Underrated Pillars of Winter Wellness

3. Prioritise restful, consistent sleep

Sleep and immunity work closely together. When you get enough rest, your body is better able to regulate inflammation and produce protective immune cells (Garbarino et al., 2021). When sleep is disrupted - whether from stress, screens, or busy routines - your defences naturally weaken.

Aim for 7–8 hours per night by:

Reducing caffeine later in the day
Creating a screen-free wind-down routine
Keeping your bedroom cool and calm

Even small improvements can leave you feeling more energised and resistant to illness.

4. Find ways to gently lower stress

Chronic stress pushes cortisol levels higher than usual, making it harder for your immune system to function properly (Alotiby, 2024). While stress can’t be avoided entirely, you can support yourself with healthy coping tools, such as:

gentle movement
mindful breathing
journaling
listening to music or a favourite podcast
staying connected with the people you love

Whatever helps you exhale - lean into it.

Vitamin D and Winter Wellness

5. Remember your vitamin D supplement

Vitamin D is essential for immune regulation, but during UK winters, sunlight levels simply aren’t high enough to maintain optimal levels. Because we only get small amounts from food, national guidance recommends supplementing between October and March.

Many people find vitamin D3 supplements easiest to absorb. A daily dose around 10μg/400 IU is appropriate for most adults, but check with your healthcare provider if you’re unsure - those required to cover up more, for example, may require supplementation all year round, or at higher doses.
