A balanced diet with plenty of fruit, vegetables, wholegrain products and healthy fats provides our body with important nutrients and strengthens the immune system. In addition, certain foods such as garlic, ginger, citrus fruits and fermented products such as sauerkraut can help to support the immune system. Regular exercise promotes blood circulation and activates our body’s immune cells. An active lifestyle can therefore help to strengthen the immune system. Sufficient sleep is also crucial for a healthy immune system. During sleep, our body recovers and repairs damaged cells. A lack of sleep can weaken the immune system and increase susceptibility to illness. In addition, stress management techniques such as meditation, yoga or breathing exercises can also help to strengthen the immune system. By paying attention to a healthy lifestyle and giving our body the support it needs, we can naturally build and strengthen our immune system. A strong immune system is the key to good health and an active lifestyle.
