Also, infections like the flu virus, mono (mononucleosis), and measles can weaken the immune system for a brief time. Your immune system can also be weakened by smoking, alcohol, and poor nutrition.
Conclusions. Over the past several years, various studies have demonstrated that the consumption of coffee has positive effects on the immune system. Nevertheless, daily caffeine intake should not exceed 400 mg/day in adults and 200 mg/day in pregnant and breastfeeding women.
The Role of Immunity Testing
You can test for the presence or level of an antibody in blood using a serology test. The test can show whether your body could protect you from getting an infection or from getting severe disease symptoms.
A lack of sleep, poor diet, anxiety, or stress can often cause a person to feel sick. These factors can make a person more susceptible to infection and illness. However, always feeling sick can also signify pregnancy or chronic illness. When sick, a person may experience stomach discomfort and vomiting.
“A lifestyle that includes eating healthy foods, physical activity, reducing stress, and getting enough sleep is known to keep your immune system in the best shape,” adds Milner, who is a leader in the discovery of rare immune deficiency disorders of children.
Vitamins B6, C and E are all known for their immune-boosting properties. You can get all of these vitamins from a well-balanced diet, so you don't need supplements. Some foods rich in these vitamins include eggs, bell peppers, spinach and almonds.
Healthy ways to strengthen your immune system
Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies such as these: Don't smoke. Eat a diet high in fruits and vegetables. Exercise regularly. Maintain a healthy weight.
But did you know that it can also enhance your immunity? Lemons are an excellent source of Vitamin C, a natural antioxidant that improves the immune system and has antibacterial and antiviral qualities. Lemon water mixed with honey can be a great way to boost the body's capability to fight diseases.
Drinking tea or warm lemon water mixed with honey is a time-honored way to soothe a sore throat. But honey alone may be an effective cough suppressant, too. In one study, children ages 1 to 5 with upper respiratory tract infections were given up to 2 teaspoons (10 milliliters) of honey at bedtime.
It is a potent antioxidant and a cofactor for a family of biosynthetic and gene regulatory enzymes. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system.
Zinc is found in cells throughout the body. It helps your immune system fight off invading bacteria and viruses. Your body also uses zinc to make DNA (the genetic material in cells) and proteins. During pregnancy, infancy, childhood, and adolescence the body needs zinc to grow and develop properly.
Asthma, familial Mediterranean fever and Crohn's disease (inflammatory bowel disease) all result from an over-reaction of the immune system, while autoimmune polyglandular syndrome and some facets of diabetes are due to the immune system attacking 'self' cells and molecules.
The function of the immune system peaks at around puberty and gradually declines thereafter with advance in age.
