A practical guide to feeling your best in the colder months As winter approaches, many people notice subtle shifts in how they feel - lower energy, changes in mood, drier airways, or a general sense of being “run down”. These seasonal changes are normal, and understanding why they happen can help people support their wellbeing in simple, natural ways. This guide explores the key factors that influence winter health, what research says about seasonal changes, and the everyday habits that help people feel their best during the colder months. 🌬️ Why winter affects us differently 1. More time indoors and shared air During winter, people spend more time inside with less airflow. This can affect: Air quality – more dust, indoor pollutants, and recirculated air Humidity – heating often dries the air Microbe circulation – people are closer together in enclosed spaces Research suggests that low humidity and close contact can make it easier for microbes to move around in shared environments. While this doesn’t mean people will get sick, it helps explain why winter is often associated with more colds and flus. 2. Reduced sunlight and circadian rhythm Shorter days mean less natural light, which can influence: Mood and motivation Sleep–wake cycles (circadian rhythm) Vitamin D levels Light is one of the main signals for the body’s internal clock. When light exposure changes, people may notice shifts in energy, sleep quality, and how “bright” or “flat” they feel emotionally. This is one reason many people feel different in winter, even if their routine hasn’t changed much. 3. Cooler temperatures and mucosal dryness Cold air holds less moisture. When people breathe it in, it can dry the: Nasal passages Throat Upper airways These tissues form part of the body’s natural barrier system. When they feel dry or irritated, people often become more aware of their breathing and throat comfort. Indoor heating can add to this dryness, especially in homes and workplaces with constant warm air. 4. Seasonal dietary changes and comfort eating Winter meals tend to be: Heavier and more comforting Higher in refined carbohydrates Lower in fresh, raw foods This can influence digestion, gut balance, and how steady or sluggish energy feels across the day. Many people naturally shift toward warm, cooked foods in winter, which can be supportive when combined with plenty of vegetables, fibre, and fluids. 5. Cold and flu season patterns Winter is often referred to as “cold and flu season”. This reflects patterns seen in many countries where: People gather indoors more often Viruses can remain stable for longer in cooler, drier air Sleep, stress, and diet may be less consistent It’s important to note that not everyone will experience frequent colds or flus, but understanding these patterns helps people make more intentional choices about rest, hygiene, and daily routines. 🥗 Nourishing the body with seasonal nutrition Winter is a great time to focus on nutrient‑dense foods that support general wellbeing. Many people naturally gravitate toward: Citrus fruits and berries – a source of vitamin C and antioxidants Leafy greens – for folate, magnesium, and other micronutrients Broths and warming soups – gentle on digestion and hydrating Fermented foods – such as sauerkraut, kimchi, yoghurt, or tonics Herbal teas – a soothing way to increase fluid intake These foods provide vitamins, minerals, antioxidants, and plant compounds that help maintain everyday vitality and complement a balanced winter diet. Inner Glow has several supplements that align with this nutritional approach - for example, Vitamin C for general immune system function or Sun Chlorella as a source of plant nutrients and chlorophyll. These fit naturally into a winter diet alongside whole foods. 🧠 Gut balance and winter wellbeing A growing body of research highlights the connection between gut balance and overall wellness. The gut is involved in: Digesting and absorbing nutrients Interacting with the immune system Communicating with the brain via the gut–brain axis During winter, when diets shift and activity levels change, many people choose to include fermented foods or probiotics to help maintain digestive comfort and regularity. A fermented tonic like Vita Biosa is a great example of a naturally fermented, probiotic‑rich product that supports everyday gut balance. Research suggests that: The gut microbiome can change with seasonal eating patterns Fermented foods may help support microbial diversity Gut health is linked to mood, energy, and overall resilience This makes gut‑supportive habits particularly relevant during the colder months, when people may be more prone to heavier meals and less movement. 🔥 Warming herbs, circulation and comfort Traditional herbal systems often emphasise warming botanicals during winter. Herbs such as: Cayenne Ginger Garlic Hawthorn have long histories of use in supporting warmth, circulation, and general vitality, especially in colder weather. Dick Quinn’s Heart Food contains these classic herbs, making it a great example of traditional winter botanicals. Modern research has explored how some of these herbs: Are used traditionally to support digestive comfort Are associated with a subjective sense of warmth Fit naturally into winter cooking (soups, stews, teas, and tonics) Including warming herbs in food and daily rituals can be a simple way to align with the season. 😴 Stress, sleep and the nervous system in winter Winter can also bring changes in routine that affect the nervous system: People may stay up later indoors but still wake early for work Screen time often increases as outdoor time decreases Stress can build up around work, family, and end‑of‑year demands Sleep and stress are closely linked to how people feel day‑to‑day. Research shows that: Consistent, good‑quality sleep supports immune function and mood Chronic stress can influence how the body responds to everyday challenges Relaxation rituals - like a warm drink, gentle stretching, or reading - can help signal to the nervous system that it’s time to unwind Building simple, repeatable evening routines can make winter feel more restorative rather than draining. 💧 Hydration, movement and daily rituals Winter wellbeing isn’t just about nutrition or supplements. People often feel better when they: Stay hydrated – cold weather can be surprisingly dehydrating, especially with heating Maintain consistent sleep routines – going to bed and waking at similar times Get fresh air and sunlight when possible – even short walks can help Keep moving, even gently – walking, stretching, or light exercise Create grounding daily rituals – such as a morning tea, journaling, or breathing practices These habits help support energy, mood, and overall resilience throughout the season. They also complement any nutritional or herbal choices people make. 🌟 A balanced approach to winter Winter doesn’t have to feel heavy or draining. With a focus on: Nourishing, seasonal foods Gut balance and fermented foods Warming herbs and traditional botanicals Hydration, movement, and rest Simple, grounding daily rituals people can support their wellbeing naturally throughout the colder months.
