Colds and flu are more common in autumn and winter due to a combination of factors. The drop in temperatures is a key factor, as cold weather constricts blood vessels and reduces blood flow, which can potentially weaken the body’s immune responses.
Additionally, the reduced sunlight during the winter months leads to lower levels of vitamin D in the body, which is crucial for immune function. This deficiency can impair the body’s ability to fight infections.
Additionally, during the winter, people spend most of their time indoors, often in close proximity to others. Increased activity indoors facilitates the transmission of viruses, especially in poorly ventilated enclosed spaces and in public places where shared surfaces are used. These conditions create an ideal environment for the easier spread of illnesses such as the common cold and flu.
Given these challenges, the winter season calls for additional measures to bolster immune health. This includes maintaining a healthy diet rich in vitamins and minerals, regular physical activity, adequate sleep and good hygiene.
Strengthening the immune system
Strengthening the immune system, especially during the colder months, involves a holistic approach focused on lifestyle and dietary habits:
- A Balanced Diet: Eating a variety of fruit, vegetables, whole grains, protein, and healthy fats is essential. These foods are rich in essential nutrients such as vitamins C and E, beta-carotene and zinc, which strengthen the immune system’s ability to fight off infections. Brightly coloured fruits and vegetables, such as blueberries, oranges, and spinach, are particularly rich in antioxidants and phytonutrients that support immune health.
- Regular exercise: moderate physical activity – around 150 minutes per week – can have numerous benefits for the immune system. Activities such as swimming, running, dancing, walking or yoga improve blood circulation, allowing immune cells to move more efficiently throughout the body. Furthermore, regular exercise can reduce the risk of chronic diseases and inflammation in the body, which further strengthens immune function.
- Get enough sleep: Sleep is really important for maintaining immunity. During sleep, the body releases cytokines, a type of protein that helps the immune system respond to infections and inflammation. A lack of sleep can reduce the production of these protective cytokines, as well as antibodies and infection-fighting cells.
- Stress management: Chronic stress exposes the body to a constant influx of stress hormones, such as cortisol, which suppress the immune system. Practices such as meditation, yoga, deep breathing exercises and spending time in nature can effectively help manage stress, keeping the immune system in top form.
- Proper hygiene: Good hygiene practices are essential for preventing the spread of viruses and other pathogens. Regular hand washing, the use of hand sanitiser and maintaining a clean environment significantly reduce the likelihood of infection and the spread of infections.
Good habits not only strengthen the immune system but also contribute to overall well-being, making the body more resistant to infections and illnesses.
Treatment for a nervous stomach
A number of studies highlight the effectiveness of probiotics in both preventing and treating colds:
- Lower risk of illness: An analysis of numerous studies shows a lower incidence of colds among those who take probiotics compared with those who do not.
- Relief of cold symptoms: probiotics have been shown to shorten the duration of cold symptoms, leading to a faster recovery.
- Reduction of colds in vulnerable patients: In individuals prone to recurrent colds, the use of probiotics significantly reduces subsequent and recurring infections.
- Shorter duration of illness: It has been found that the use of probiotics reduces the duration of colds and flu.
For additional support of your immune system and overall health, you can add nutritional supplements to your daily routine. One product worth mentioning is the powerful synbiotic B-protekt. B-protekt is a highly effective synbiotic – a combination of probiotics and prebiotics containing a unique blend of 5 probiotic bacterial strains and the prebiotics inulin and pectin, which create a favourable environment for the development of beneficial bacteria in the gut. B-protekt is enriched with vitamins in optimal doses that have a beneficial effect on gut immunity, and each probiotic strain has a unique, specific mechanism of action in the relevant part of the gastrointestinal tract. This makes B-protekt an excellent combined product for various intestinal disorders during and after antibiotic therapy, diarrhoea or constipation, changes in diet, travel and stress. Regulating the processes in the gastrointestinal tract contributes to a stronger immune system and better overall health.
Additional health advice
- Vitamin C intake: Although taking vitamin C is not a 100% guarantee against colds and flu, it certainly plays a role in maintaining a healthy body. Include citrus fruits, berries, peppers and green leafy vegetables in your diet.

- Good foods for boosting immunity: Foods rich in vitamin D (oily fish, eggs), zinc (nuts, seeds, pulses) and antioxidants (berries, green tea) can be very beneficial for immunity. Foods rich in beneficial probiotics include yoghurt, kefir, sauerkraut, kimchi and kombucha, which also support gut health.
In conclusion, probiotics are an important and positive factor in maintaining our health during the winter season or when the health of our gut is compromised. They play a key role in supporting the immune system, and regular consumption of probiotics can reduce the risk of various winter illnesses, including respiratory infections. Good habits and the right choices play a significant role in good health. Including dietary supplements is an easy way to turn good choices into new habits for a strong immune system every day.
