9 facts about the immune system that you have to know

Data of the most important thing you have to know about your immune system, what they give you!

1- The immune system has control over our social interactions

Last year, a team of scientists from the University of Virginia School of Medicine (UVA, USA) discovered that the brain is connected directly to the immune system by previously unknown lymphatic vessels. Now, the same team has found that the immune system affects and even controls the social behavior of living beings. This surprising finding could have implications for disorders such as autism.

2- The skin secretes antibacterial substances

These substances explain why we do not get up in the morning with a layer of mold growing on the skin - most of the bacteria and spores that settle on the skin die quickly.

Tears and mucus contain an enzyme called lysozyme, which breaks down the cell wall of many bacteria.

3- What happens if our immune system does not work well?

All human organisms have an immune system; But there are cases of people suffering from a condition called immunodeficiency, that is, that their immune systems are weak to fight against infections. To strengthen the immune system there are medicines and also among the therapeutic options is bone marrow transplantation.

On the other hand the system can also have a disease that causes it to decode badly, interpret enemy cells as their own, and attack them. This produces autoimmune diseases such as type 1 diabetes, rheumatoid arthritis, celiac disease, and multiple sclerosis, among others. There are more than 80 diseases of this type.

4- Did you know that the symptoms of the infections that we suffer are usually caused by the immune system and not by pathogens?

Most of the time it is the immune system performing its defensive function, that is, reacting to microorganisms. For example, inflammation, fever. Allergies happen because of an "exaggerated immune system" reaction. People who are affected by certain aspects of the environment, whether dust, pollen, moisture or some types of food or products, which release histamines in their bodies, causing respiratory problems, rhinitis, skin rashes, eye discharge , etc.

5- Lack of sleep affects the immune system

Sleep deprivation causes the immune system to react in the same way as after exposure to physical stress, according to a study published in the journal Sleep.

6- Stress

Chronic stress can affect certain responses of the immune system, according to a study published in the scientific journal Health Psychology. It can increase the susceptibility to certain inflammatory diseases such as allergies and cardiovascular or autoimmune diseases. The same result reflected a study developed by a team of researchers from the Carnegie Mellon University of Pittsburgh, which relates the increase in susceptibility to the disease with an alteration in the capacity of the body's inflammatory response, caused by chronic stress.

7- Exposure to germs as training

We need the germs to live. The health of our body depends entirely on the interaction with the pathogens, is what makes the immune system is trained for the attacks of viruses, bacteria and fungi and know how to respond to them.

Everyone defends

Even simple unicellular organisms such as bacteria, have a rudimentary immune system, in the form of enzymes that protect against bacteriophage infections.

8- Are there people without an immune system?

All human organisms have an immune system; However, sporadically there are cases of people suffering from a condition called immunodeficiency, that is, that their immune systems are weak to fight infections. The only solution so far is a bone marrow transplant.

9- What are allergies?

Some people are affected by certain aspects of the environment, be it dust, pollen, moisture or some types of food, which release histamines in their organism.
