Immunity is the capability of multicellular organisms to resist harmful microorganisms from entering it. Immunity involves both specific and nonspecific components. The nonspecific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up.
Innate immunity, also called native immunity, exists by virtue of an organisms constitution that is its genetic make-up, without an external stimulation or a previous infection. It is divided into two types: (a) Non-Specific innate immunity, a degree of resistance to all infections in general. (b) Specific innate immunity, a resistance to a particular kind of microorganism only.
Adaptive immunity can be sub-divided depending on how the immunity was introduced in ‘naturally acquired’ through chance contact with a disease causing agent, whereas ‘artificially acquired immunity’ develops through deliberate actions such as vaccination.
A strong immunity not only safeguards us from colds and coughs but also keeps us away from diseases like hepatitis, lung infection, kidney infection, bowel infection, autoimmune conditions.
All of us are surrounded with pathogens. We live, drink, eat and breathe pathogens without our knowledge. But not everyone falls sick. The ones with a strong immune system cope better. Thus a strong immunity is really the first and last line of defense of all that ails us. While a blood report can reveal a lot about low immunity, our body also tries to give certain symptoms .Here are few
If you find yourself falling sick more often than others, complain of recurrent cold, sniffles (which may be allergy driven like pollen allergy), persistent cough, sore throat, skin rashes, then it’s highly likely that your immune system is compromised.
Some people experience allergic reactions more often than others. They cannot respond to certain pollen, dust, and environmental agents that impact your skin or mucus, and that immediately affect health. If that is the case for you, it is possible that you have a weak immune system.
Poor gut health
Around 80% of our immunity lies in our gut. Chronic constipation, indigestion, acidity, bloating, flatulence, are signs of a poor gut health, which speak volumes about our immunity. Bad gut health also means an imbalance between good and bad gut bacteria. Hence probiotics make an important part of any healthy diet.
Fatigue can have a lot of causes. But when they are continuous, when you wake up in the morning for example and feel exhausted, when you end up tired from the smallest things, when the difference in temperature causes you to get depressed or nausea, etc… This may be due to your weak immune system.
What dietary factors are important in low immune function?
Optimal immune function requires a healthy diet that is (1) rich in whole, natural foods, such as fruits, vegetables, whole grains, beans, seeds, and nuts, (2) low in fats and refined sugars, and (3) contains adequate, but not excessive, amounts of protein. On top of this, for optimal immune function, an individual should drink five or six 8-ounce glasses of water per day (preferably pure); take a high potency multivitamin-mineral supplement; engage in a regular exercise program of at least 30 minutes of aerobic exercise and 5-to-10 minutes of passive stretching daily; perform daily deep breathing and relaxation exercises; take time each day to play and enjoy family and friends; and still get at least 6-to-8 hours of sleep daily.
