Immune System - What Causes a Weaken Immune System?

The immune system is the set of cells and their activity against antigens, or infectious agents that comprises of the body’s defense system against diseases. The immune system does a great job of keeping people healthy and preventing infections. However, sometimes problems with the immune system can lead to illnesses and infections.
There are many causes that weaken our immune system:

1. Overdosing on sugar:

Intake of high amounts of sugar for a prolonged period of time can reduce the ability of white blood cells to kill germs by 40 percent. The immune-suppressing effect of sugar starts less than thirty minutes after ingestion and may last for five hours.

2. Excessive alcohol drinking
Excessive alcohol drinking can harm the body’s immune system in two ways
a) It produces an overall nutritional deficiency, depriving the body of valuable nutrients.
b) Excessive alcohol drinking can reduce the ability of white cells to kill germs, and suppress the ability of the white blood cells to multiply causing intoxication resulting in suppressed immunity and liver infection.

3. Food allergens
The immune system recognizes an otherwise harmless substance as a foreign invader and attacks it, causing an allergic reaction. Before the battle, the intestinal lining was like a wall impenetrable to foreign invaders. After many encounters with food allergens, the wall is damaged, enabling invaders and other potentially toxic substances in the food to get into the bloodstream and make the body feel fatigued.

4. Intake high amounts of saturated and trans fats
Obesity can lead to a weakened immune system. It can affect the ability of white blood cells to multiply, produce antibodies, and prevent inflammation.

5. Inadequate amount of sleep
An inadequate amount of sleep can lead to a depressed immune system. Our body requires sleep to restore it’s depleted energy during sleeping and allows white blood cells to re- strengthen themselves.

6. Vitamin, nutrition and mineral deficiency
Vitamin, nutrition and mineral deficiency reduce the oxygen levels in the bloodstream which are essential to our body’s cells and increases the risk of inflammation of the prostate, liver, etc.

There are many more factors such as emotional stress, physical stress, inadequate protein calorie, and age.
