Theย immune ย systemย keeps a record of every microbe it has ever defeated, in types of white blood cells (B-lymphocytes and T-lymphocytes) known as memory cells. This means it can recognise and destroy the microbe quickly if it enters the body again, before it can multiply and make you feel sick.
Some infections, like theย fluย and theย common cold, have to be fought many times because so many different viruses or strains of the same type of virus can cause these illnesses. Catching a cold or flu from one virus does not give you immunity against the others .
How to boost immune system
#1. According to the National Institutes of Health, there are many healing benefits of chicken soup. Your favorite recipe likely has properties that fight inflammation, promote hydration and get mucus flowing. Drink plenty of liquids, such as water, broth or sports drinks with electrolytes.
#2.Consuming adequate amounts of several vitamins and mineralsโincludingย vitamin A, vitamin C, vitamin D, vitamin E, selenium, and zincโis important for proper immune function, and clinical deficiencies of these nutrients weaken immunity and can increase susceptibility to infections.
#3.There appears to be a connection between nutrition and immunity in the elderly. A form of malnutrition that is surprisingly common even in affluent countries is known as “micronutrient malnutrition.” Micronutrient malnutrition, in which a person is deficient in some essential vitamins and trace minerals that are obtained from or supplemented by diet, can happen in the elderly. Older people tend to eat less and often have less variety in their diets. One important question is whether dietary supplements may help older people maintain a healthier immune system. Older people should discuss this question with their doctor.
Secret tip for immunity
While long-term stress is generally harmful, short-term stress can be protective as it prepares the organism to deal with challenges. This review discusses the immune effects of biological stress responses that can be induced by psychological, physiological, or physical (including exercise) stressors.
We have proposed that short-term stress is one of the nature’s fundamental but under-appreciated survival mechanisms that could be clinically harnessed to enhance immunoprotection. Short-term (i.e., lasting for minutes to hours) stress experienced during immune activation enhances innate/primary and adaptive/secondary immune responses.
Thus, short-term stress can enhance the acquisition and/or expression of immunoprotective (wound healing, vaccination, anti-infectious agent, anti-tumor) or immuno-pathological (pro-inflammatory, autoimmune) responses. In contrast, chronic stress can suppress protective immune responses and/or exacerbate pathological immune responses.
