Real-Life Examples, Science-Backed Insights, and Relevant Studies
What to Do (with Real-Life Examples)
1. Stay Hydrated with Warm Drinks
Example:
If you’re used to grabbing a soda or cold drink during lunch, swap it for a warm ginger tea. In many Asian cultures, ginger tea is traditionally enjoyed during cold seasons as it’s believed to enhance circulation and warmth.
Science:
Research shows that warm fluids help in mucus drainage, soothing the respiratory tract and reducing cold symptoms (Ebbeling et al., 2017).
2. Incorporate Warming Spices
Example:
Try adding cinnamon and cloves to your morning oatmeal or tea. Indian chai often incorporates these spices, known for their warming properties.
Science:
Studies have shown that ginger and turmeric have anti-inflammatory effects, helping the immune system function optimally in colder months (Aggarwal et al., 2013).
3. Eat Seasonal Fruits and Vegetables
Example:
Winter citrus like oranges and grapefruits are high in Vitamin C, boosting immunity. Farmers’ markets often offer seasonal vegetables like kale and carrots, both of which are rich in essential nutrients.
Science:
Research confirms that Vitamin C supports immune defense by promoting epithelial barrier functions and enhancing white blood cell function (Carr & Maggini, 2017).
4. Include Lean Proteins
Example:
Instead of a heavy carb-based lunch, opt for a chicken or tofu soup, which provides protein without excessive fats. Protein-rich soups are popular in winter due to their warming and filling nature.
Science:
Protein is essential for immune cell formation and repair, especially for amino acids required by immune cells (Calder, 2021).
5. Layer Up with Natural Fabrics
Example:
Wear wool or fleece layers instead of synthetic fabrics, which can trap moisture and make you feel cold. Wool is widely used for winter clothing as it insulates even when wet.
Science:
Natural fibers like wool help regulate body temperature better than synthetic materials, reducing the risk of hypothermia in cold weather (Collins, 2012).
6. Get Daily Sunlight
Example:
Aim for a short walk during midday when sunlight is most abundant. Many northern countries emphasize “sunlight therapy” as a remedy for winter blues.
Science:
Vitamin D, produced by sunlight exposure, plays a role in immune function by activating pathogen-fighting cells (Holick, 2007).
7. Exercise Regularly
Example:
Yoga or indoor stretching routines can help keep muscles warm and improve blood flow without venturing outside in extreme cold.
Science:
Physical activity has been shown to boost immune health, increasing circulation of antibodies and white blood cells (Pedersen & Hoffman-Goetz, 2000).
8. Use a Humidifier
Example:
Running a humidifier overnight can prevent dry skin and sore throat. In Japan, humidifiers are a common household item used in winter to maintain air quality.
Science:
Studies indicate that humidifiers can reduce flu survival rates in the air, as the virus survives longer in dry air (Noti et al., 2013).
9. Prioritize Sleep
Example:
Commit to winding down early by reading before bed instead of watching TV, as blue light can disrupt sleep.
Science:
Studies show that sleep deprivation weakens the immune response, making the body more susceptible to colds and flu (Prather et al., 2015).
10. Practice Mindfulness and Stress Management
Example:
Begin the day with a short meditation or journaling session. In Scandinavian countries, “hygge” practices, which focus on coziness and mental relaxation, are popular in winter.
Science:
Mindfulness practices have been linked to reduced stress hormones, supporting immune function (Black & Slavich, 2016).
What Not to Do (with Real-Life Examples)
1. Don’t Skip Meals
Example:
If you're busy, keep healthy snacks like nuts on hand to avoid missing meals. People in colder regions often eat hearty breakfasts to keep energy levels stable.
Science:
Skipping meals can lower your blood sugar, making it harder for your body to generate heat (Willis et al., 2014).

Example:
For every cup of coffee, drink a glass of water or switch to green tea.
Science:
Studies show caffeine can lead to dehydration, which isn’t ideal for immune health in winter (Grandjean et al., 2003).
6. Don’t Skip Handwashing
Example:
Make a habit of washing hands immediately upon coming home, a practice that has shown to significantly reduce infection risk.
Science:
Handwashing is one of the simplest and most effective ways to prevent the spread of infections (Aiello et al., 2008).
7. Avoid Neglecting Skin Care
Example:
Moisturize immediately after showering and use a gentle cleanser to prevent skin from drying out.
Science:
Studies indicate that dry, cracked skin can increase susceptibility to infections as it creates an entry point for pathogens (Proksch et al., 2008).
8. Don’t Stay Sedentary
Example:
Set an hourly timer to get up and stretch if you’re working from home, even doing some lunges or squats.
Science:
Prolonged inactivity can reduce circulation and is associated with reduced immunity (Pedersen et al., 2000).
9. Avoid Close Contact with Sick Individuals
Example:
Avoid crowded places during peak flu season, as done in many countries with high winter flu rates.
Science:
Close contact is a primary way viruses spread, especially in winter when people are indoors more often (WHO, 2017).
10. Don’t Ignore Symptoms of Illness
Example:
Rest and drink fluids at the first sign of a sore throat or cold. In Finland, people often take a “sick sauna” day to sweat out early symptoms.
Science:
Early symptom management helps prevent the progression of infections, supporting faster recovery (Eccles, 2005).
Conclusion
Staying healthy and warm throughout winter is a balance of nurturing your body from the inside and following some mindful lifestyle habits. The combination of hydration, proper nutrition, and immune support offers your body a buffer against the season’s challenges.
