The immune system’s job is to defend your body against disease-causing microorganisms. But this is not a foolproof system. There are times that a germ invades successfully and ends up making you sick.
So the question is this:
How can you prevent this and improve your immune system?
The first thing to do is to choose a healthy lifestyle. Maintaining good health is the best thing you can do to naturally keep your immune system strong and healthy. Every part of the body, including your immune system, functions smoother when you follow healthy-living strategies such as:
● Don’t smoke.
● Eat a diet high in fruits and vegetables.
● Exercise regularly.
● Maintain a healthy weight.
● If you drink alcohol, drink only in moderation.
● Get adequate sleep.
● Wash hands frequently and
● Cook meat thoroughly.
● Minimize stress.
As we age, our immune system becomes weak, which in turn contributes to more infections and more diseases. Respiratory infections, influenza, the COVID-19 virus, pneumonia are all leading causes of death in people over 65 worldwide.
There is a reduction in immune response to older people’s response to vaccines. Studies of influenza vaccines have shown that older people find the vaccine far less effective than healthy children (over age 2). But despite this, vaccinations for influenza and S. pneumoniae have significantly lowered the rates of sickness and death in those over 65.
There is a definite connection between nutrition and immunity in older people. Micronutrient malnutrition is a form of malnutrition that is surprisingly common even in affluent countries. It means deficiency of some essential vitamins and trace minerals that are obtained from or supplemented by diet, can happen in the elderly. Older people eat less and often do not have much variety in their diets. One important question is whether dietary supplements can be helpful for older people to maintain a healthier immune system. Discuss this with your doctor.
Various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — change your immune responses.
Modern medicine understands the close relationship between the mind and the body. A wide variety of maladies, including stomach upset, hives, and even heart disease, can occur or exacerbate due to emotional stress.
Stress is difficult to define. What can be stressful for one may not be for another. When people are regularly in a stressful situation, it is difficult for them to measure how much stress they feel.
But a definite way to improve your immune system is to reduce the stress in your life. Doing yoga or meditation is a good way to relieve stress.
Regular exercise is also one of the pillars of healthy living. It helps in improving cardiovascular health, lowering blood pressure, helping control body weight, and protecting against a variety of diseases. Just like a healthy diet, exercise also contributes to general good health and therefore to a healthy immune system. It contributes even more directly by promoting good circulation, allowing the cells and substances of the immune system to move through the body freely and perform their job efficiently.
