8 Habits that destroy our Immune System

Our health is directly related to the state of the immune system: this means that the stronger the latter, the higher our resistance to viruses and various diseases that can attack our body. When we have a weak immune system, we are more likely to suffer from colds and other viral diseases that can seriously affect the body.

Immune system

Most of our daily habits directly affect the state of our immune system, especially when we reach old age. That’s why healthy habits are essential for good health. In this article, we will tell you about bad habits and factors that can destroy our immune system.

Excess sugar intake

Excessive sugar intake can cause the immune system to lose up to 40% of its ability to destroy microbes. According to research, the use of sugar can affect the immune system, starting from 5 minutes after consuming it and lasting up to 5 hours. For the immune system to function well, it is important to give it a good supply of vitamin C: however, when we consume a lot of sugar, it corrodes the vitamin C present and destroys the structure of protective cells.

Drinking alcoholic beverages

The consumption of alcoholic beverages has a large number of negative health consequences, as they prevent the absorption of essential nutrients and, consequently, cause a nutritional deficiency. When a person drinks alcohol in excessive amounts, it prevents the proliferation of leukocytes, and cells that absorb foreign particles generate tumor necrosis factors. When the body does not produce the required number of cells, the immune system weakens.

The immune system also perceives as a threat substances that may seem harmless, such as dust, pollen, or smoke. As a result, it goes into a state of readiness and causes an allergic reaction, it can destroy the cell wall that blocks external invaders, making the immune system more vulnerable.

Lack of sleep

“Insomnia” is one of the problems that many people face these days. Multiple obligations, stress, and depression, among other things, can prevent a person from getting enough sleep and make it very difficult for him to have a good rest. According to a study by the University of Chicago, people who sleep 4 hours a day or less can produce only half of the antibodies fighting the common cold, compared to those who sleep 8 hours a day or more.

Lack of sleep


It has been proven that stress negatively affects physical and mental health. When a person is constantly exposed to stressful situations, his immune system begins to weaken, losing the ability to fight infections, viruses, and microbes. What happens is that the number of white blood cells decreases, causing a weakening of the immune system. The same thing happens to those who are going through a period of depression or trying to overcome trauma.

Using other people’s things

The most common germs and viruses are almost always transmitted after sharing items and/or tools intended for personal use. Unfortunately, we never pay attention to the path that an object could have taken when it reached our hands, and we use it without taking preventive measures. We don’t need to get hung up on microbes, but it would be good to try to assess where the object came from to avoid infection with diseases or infections.

Abuse of antibiotics

Antibiotics are designed to fight the most serious infections. They are usually very effective, but exceeding them can lead to the activation of the mechanism of antibiotic resistance in the body and, consequently, become more vulnerable to infection with infections and diseases. Studies have shown that those who take antibiotics constantly have a weaker immune system and get sick more easily.

Sedentary lifestyle

Currently, a sedentary lifestyle has become one of the biggest health problems in the world, since people who lead such a lifestyle usually suffer from obesity, cardiovascular diseases, and a weak immune system. When a person does not exercise, adheres to a poor diet, and is not very active during the day, he usually accumulates more toxins and becomes more susceptible to infection with diseases and infections. To avoid stress, it is recommended to exercise for at least 30 minutes a day, follow a healthy diet, drink water, and do something interesting.

  • Pentapeptide-3 is an anti-wrinkle ingredient that is very potent. It has been proven to reduce wrinkling by 49%. The primary use of Pentapeptide-3 was for the decrease in Crow’s feet wrinkles, but it has now been found to be effect on other facial wrinkles. Studies have found Pentapeptide-3 to be effective in anti-aging problems. It is been tested in creams and has similar results to Botox in partially paralyzing the muscles and reducing fine lines and wrinkles.Pentapeptide-3 stimulates the “matrix” layers in the skin — primarily collagen and fibronectin. When stimulated, the skin produces more collagen. Loss of collagen is what leads to thinning skin and the wrinkling of newly inelastic skin.
