Do you know that the immune system is a separate organ? And this book tells about him everything that is known to doctors and scientists today. You will learn about the structure and origin of our immune system, its mistakes, why they happen and how they can be corrected, how we can support it in everyday life. What role do, for example, mother's milk or childhood vaccinations play? Why do men still die earlier than women? How does “rebooting” the immune system after chemotherapy work? How much dirt is acceptable in everyday life? And why is our body’s ability to protect itself better in the morning than in the evening? Attention! The information contained in the book cannot serve as a substitute for medical advice. You should consult with a specialist before taking any recommended actions.
