Understanding the impact of modern living on our immune systems and how to enhance our health.
Over the past decade, the world has witnessed a series of epidemics, including SARS, Bird flu, Swine flu, Ebola, Marburg virus, and the deadly Covid pandemic. A century ago, infectious diseases wreaked havoc due to the lack of effective measures or medicines to combat infections.
Today, despite the availability of numerous medicines for prevention and cure, and significant advancements in medical science, it is disheartening to see individuals succumbing to infectious diseases. This issue is not confined to developing countries; even in developed Western nations, where nutritious food is abundant and hygiene standards are high, people continue to suffer from infectious illnesses.
To address this alarming trend, individuals must engage in introspection regarding the decline in immunity. Nature has equipped every human and living organism with a defense mechanism known as the immune system, which plays a crucial role in preventing and controlling infections. Despite this sophisticated defense, many still experience infectious diseases.
Malnutrition, particularly protein deficiency, is a significant factor that undermines the body’s immunity. Antibodies, which are essential for combating infections, are primarily composed of proteins. Additionally, deficiencies in vitamins such as Vitamin C, folic acid, and essential micronutrients like zinc, copper, and selenium can diminish the body’s disease-fighting capabilities. Obesity, another form of malnutrition, also disrupts the immune system.
Chronic exposure to smoke and fumes, as seen in smoking, can impair the immune system by irritating the protective inner layers of the body. Certain medications, including corticosteroids and anti-cancer drugs, may retard disease processes but simultaneously weaken the immune response. Furthermore, chronic conditions such as uncontrolled diabetes, chronic renal failure, HIV/AIDS, and cancers increase vulnerability to infections.
Industrial development has led to exposure to over 1,000 different chemicals, raising concerns among scientists regarding their harmful effects. Synthetic pesticides, designed to eliminate pests, can damage the immune system. Chemicals found in processed foods, such as antibiotic and hormone-treated meat products and preservatives in fast, ready-to-eat foods, have been shown to be detrimental to immune health.
Vinyl chloride, used in PVC manufacturing, is linked to cancer, while mattresses made from vinyl and polyurethane foam can harm the immune system and potentially cause cancer. Perfluorinated compounds (PFCs), commonly found in non-stick cookware, waterproof clothing, and fast-food packaging, have been shown to reduce immune responses in children post-vaccination. The list of harmful chemicals is extensive, and our environment is rife with substances that compromise our ability to fight diseases.
Long-term exposure to low-dose radiation from everyday appliances like microwave ovens and mobile phones can damage lymphocytes, the cells involved in immunity, leading to various diseases.
Moreover, inadequate relaxation and high stress levels can weaken the body’s defenses. A diet rich in proteins, antioxidants, essential fatty acids (particularly omega-3 fatty acids), and micronutrients is vital for maintaining and enhancing the immune system. Foods such as fresh green leafy vegetables, onions, carrots, fruits, fish, walnuts, soybeans, garlic, and honey are particularly beneficial.
Adopting an organic lifestyle is essential to mitigate the harmful effects of chemicals. Instead of relying on fast, processed foods, individuals should prioritize freshly cooked, nutritious meals.
The use of plastics and polythene poses additional health risks. Rwanda’s effective ban on plastic use serves as a commendable example for both environmental and human health. Ultimately, a disciplined and healthy lifestyle is crucial for improving the immune system.
Good health can only be achieved when the body’s immunity is strengthened, thereby controlling diseases.
