The Immune System and the Brain

The immune system and the brain are interconnected in maintaining health. The immune system defends the body from infections and illnesses by identifying and attacking harmful pathogens. The brain controls thoughts, emotions, and bodily functions, and communicates with the immune system through chemical signals. This connection means that stress, inflammation, or illness can influence mental health, and vice versa. Recent research shows they work together to protect the body, highlighting the importance of both mental and physical well-being in overall health.
