Top Health Tips for the Winter Season with Functional Mushrooms

Live Better

The winter season has set in, often accompanied by comfy blankets and perhaps a cup of our DIRTEA Cacao to get you all warm and cosy. This time of year also brings about certain health challenges, from colds and flu to lethargy and low-moods. But to make the most of this winter and keep your health optimised, consider these essential tips coupled with the powerful benefits of functional mushrooms.


The colder months often coincide with an increased susceptibility to illnesses. An article in CNN Health explains that colds are more common in winter months due to the drop in temperature.  The 2022 study published in The Journal of Allergy and Clinical Immunology states that reducing the temperature inside the nose by as little as 9 degrees Fahrenheit (5 degrees Celsius) kills nearly 50% of the billions of helpful bacteria-fighting cells and viruses in the nostrils.(1)

To adapt your immune system, focus on a balanced diet rich in vitamins and minerals. Incorporate functional mushrooms like Reishi, which contain polysaccharides and beta-glucans, which may help fortify the body's defences against colds and put our body into its ready state.



The dry winter air and indoor heating can also dehydrate your body. While the temptation to indulge in hot beverages like coffee and tea is strong during winter, remember to drink ample water. Did you know that dehydration (even mild dehydration) negatively impacts physical performance, alertness and cognitive focus, thereby causing “brain fog?” To ensure proper hydration, you should consume 8 oz (237 mL) of fluid per hour for the first 10 hours of your day. A tip is to keep a glass of water by your bedside and let it be the first thing you drink. Consider sipping on herbal teas infused with Chaga mushroom extract (or even a Chaga tea on its own), renowned for their antioxidant content; this mushroom powerhouse not only supports overall well-being and hydration but also has a lovely earthy taste. 


It's easy to slip into a sedentary lifestyle during the winter, but staying active is crucial for your overall health. In one study from 2011, 1,000 people were studied for three months by tracking their lifestyles, such as diet, exercise and exposure to stressful events and how often they were sick, such as upper respiratory tract infection – for instance, the common cold.(2) It was found that those who exercised five or more days per week were 43% less likely to be sick with an upper respiratory.

To aid post-exercise recovery, consider consuming Cordyceps mushrooms, which not only have a spectacular nutty taste but also contain Cordycepin, which may enhance stamina and endurance.


Warm, hearty, warm meals are comforting in winter, but choosing the right foods will help keep us warm and support our immune system and overall health. Opting for nutrient-dense foods rich in vitamins, minerals, and antioxidants is crucial. Incorporating seasonal produce like root vegetables (sweet potatoes, carrots, beets), winter squashes, dark leafy greens (kale, spinach), citrus fruits (oranges, grapefruits), and cruciferous vegetables (broccoli, cauliflower) can provide essential vitamins such as vitamin C, vitamin K, and antioxidants. Additionally, incorporating protein-rich foods like lean meats, fish, beans, lentils, and nuts helps to maintain energy levels and supports muscle health during the colder months. Healthy fats found in avocados, olive oil, nuts, and seeds are beneficial for maintaining skin health and providing sustained energy. Warm spices like ginger, turmeric, cinnamon, and garlic add flavour and offer potential immune-boosting and anti-inflammatory properties.


The holiday season can bring about increased stress. Ensure you get adequate rest and practice stress-relieving activities like meditation, yoga, or simply taking time for yourself. Lion's Mane and Reishi mushrooms are believed to possess adaptogenic properties that may help keep your mind rested, focused and promote relaxation.


With shorter days, getting enough sunlight becomes crucial. Spend time outdoors when possible and consider supplementing with vitamin D, which plays a vital role in maintaining immune function and mood regulation. A recent study suggests that approximately 1 billion people worldwide are affected by vitamin D deficiency, and around 50% of the global population has vitamin D insufficiency.(3) Eating foods that are rich in vitamin D will also help.(4) Interestingly, mushrooms are the only non-animal species to secrete vitamin D. 


Consult a Healthcare Professional

Before incorporating any new supplements or significant changes to your diet, it's advisable to consult a healthcare professional, especially if you have underlying health conditions or are taking medications.

By combining these winter health tips with the goodness of functional mushrooms, you can fortify your body's defences, boost immunity, and enhance overall wellness during the chilly season. Remember, a holistic approach to health, incorporating diet, exercise, rest, and natural supplements, can go a long way in ensuring your well-being throughout winter.

Stay warm, stay healthy, and embrace the magic of the winter season!
