❓ Frequently Asked Questions
Q: How can I boost my immune system?
A: While there’s no magic bullet, maintaining a healthy lifestyle through balanced nutrition, regular exercise, sufficient sleep, and stress management can significantly support your immune system’s function.
Q: What is the difference between innate and adaptive immunity?
A: Innate immunity is your body’s first line of defense, providing a rapid, non-specific response. Adaptive immunity is slower but more specific, learning and remembering past threats to provide long-term protection.
Q: What are antibodies and how do they help fight infection?
A: Antibodies are proteins produced by the immune system that recognize and bind to specific antigens (foreign substances). This binding neutralizes the threat and marks it for destruction by other immune cells.
Q: What role do vaccines play in immunity?
A: Vaccines introduce a weakened or inactive form of a pathogen (or its components) to stimulate the immune system to produce antibodies and memory cells. This provides protection against future infection with the real pathogen.
Q: Is it possible to have an overactive immune system?
A: Yes, autoimmune diseases occur when the immune system mistakenly attacks the body’s own tissues, leading to chronic inflammation and damage. Examples include rheumatoid arthritis and lupus.
Q: Can stress weaken my immune system?
A: Yes, chronic stress can suppress the immune system by releasing hormones like cortisol, which can interfere with the function of immune cells and make you more susceptible to illness.
