During the cold season, the body’s defense mechanisms weaken, increasing the risk of various infections. In winter, reduced immunity is often caused by vitamin D deficiency, an unbalanced diet, and low physical activity. During this period, it is important both to reduce the risk of weakened immunity and to recognize any symptoms early. The immune system, which regulates the body’s defense mechanisms, becomes more sensitive in winter and may require additional support.
Main causes of weakened immunity during the winter months
In winter, weakened immunity is caused by several factors.
The most common reasons include:
- Reduced sunlight exposure and vitamin D deficiency
- Temperature fluctuations in the environment
- Spending more time in poorly ventilated spaces
- Unbalanced diet and deficiencies in vitamins and minerals
- Stress and disrupted sleep patterns
- Decreased physical activity
These factors collectively weaken the immune system and reduce the body’s resistance to illnesses.
What are the symptoms of immune weakness?
Symptoms of a weakened immune system can vary, but the most common complaints include:
- Frequent colds and flu infections
- Prolonged recovery periods
- Persistent fatigue and low energy
- Skin and nail problems
- Sleep disturbances
- Quick exhaustion
- In some cases, slow healing of wounds
These signs may indicate that the immune system needs additional support.
Foods that boost immunity in winter
Nutrition plays a key role in strengthening the immune system. During the winter months, it is beneficial to include the following foods in your daily diet:
- Citrus fruits (a rich source of vitamin C)
- Fish and foods containing Omega-3
- Garlic and ginger
- Honey and propolis
- Green leafy vegetables
- Nuts such as hazelnuts and almonds
- Probiotic foods like kefir and yogurt
These foods are among the most recommended for boosting immunity and help support the body’s natural defense mechanisms.
Tests to check immunity
If you frequently fall ill during the winter season, it is important to assess your immune system through laboratory tests.
The main tests used for this purpose include:
- Blood tests (white blood cell count, lymphocyte percentage, etc.)
- Assessment of vitamin and mineral levels
- PCR tests for flu and other respiratory infections
- Evaluation of allergic reactions
- Analysis of chronic inflammatory markers
These tests provide an accurate assessment of your immune system and allow for the development of an appropriate treatment plan. It is particularly important to note that immune testing is one of the most recommended methods by doctors for evaluating the increased risk of illnesses during the winter months. At the same time, vitamin check-up packages accurately measure the levels of essential nutrients in the body and help create a personalized support plan. All of these examinations are, of course, available at our health center. By visiting Saglam Aile Medical Center, you can undergo all the diagnostic tests specifically recommended for your needs.
