Immunity is the capability of multicellular organisms to resist harmful microorganisms. Immunity involves both specific and nonspecific components. Immunity refers to the body’s ability to prevent the invasion of pathogens. An immune response is the body’s defense system to fight against antigens and protect the body. There are several types of immunity, including innate immunity, passive immunity, and acquired/active immunity.

Boost Your immunity :-

• Vitamin C is one of the biggest immune system boosters of all. Foods rich in vitamin C include oranges, grapefruits, tangerines, strawberries, bell peppers, spinach, kale and broccoli. Daily intake of vitamin C is essential for good health because your body doesn’t produce or store it.
• Vitamin B6 is vital to supporting biochemical reactions in the immune system. Vitamin B6 also is found in green vegetables and in chickpeas, which is the main ingredient in hummus.
• Vitamin E is a powerful antioxidant that helps the body fight off infection. Foods rich in vitamin E include nuts, seeds and spinach.
• Alcohol and other addictive substances Certain habits like smoking, vaping, alcohol consumption and substance abuse have a direct correlation between weakened body defenses and respiratory illnesses.
• Supplements If you’re concerned whether you are getting the right amount of nutrients from your diet, consult with your doctor about a supplementation regimen to boost your immune system. Here are a few common supplements and superfoods that can help.
• Diet and your immune system Healthy immune system warriors need good, regular nourishment. The food you eat plays a key aspect in determining your overall health and immunity.
• Practice meditation Too much stress releases the hormone known as cortisol, which impairs your response to immediate surroundings and makes your body susceptible to infections; you are left feeling constantly anxious.
