The immune system is the natural defense of our body; it is a mechanism that is found in the body of every living being and that is responsible for protecting us against external agents that can cause us damage (toxins, bacteria, viruses, poisons, etc).

Maintaining a strong immune system is important precisely because of that, because if it weakens, the chances of getting sick increase. If you want to know exactly why our immune system decays and why we really get sick, don't miss this article. In addition, we talk about how you can avoid getting sick so easily. Take note!
Why we get sick – the reasons
The question why we get sick is difficult to answer, since it can be due to internal or external factors capable of attacking your body without you being able to do anything about it. There are several causes why you can get sick, however, the most frequent are those related to food and lifestyle.
The intestine
The intestine is responsible for filtering nutrients, absorbing water and certain electrolytes and synthesizing some fundamental vitamins for your body, as well as eliminating waste that the body does not need. Therefore, it is of special importance that its operation is always optimal; you should avoid constipation, diarrhea and intestinal parasites, as this prevents the intestine from performing its functions properly. Thus, a gut that does not function as it should can be a source of disease.
Food
A good diet is essential to avoid the appearance of diseases; it is necessary to eat foods that promote the proper functioning of the body, as well as avoid those that can seriously harm health. The consumption of saturated fats, for example, can become a problem when it comes to enjoying good health, as well as the scarcity of certain nutrients.
Bad habits and stress
Bad habits (smoking, habitual drinking, sedentary lifestyle, drug use, poor diet or hygiene, etc.) make us much more vulnerable, so it is noticeably easier for a person who leads an unbalanced and unhealthy lifestyle to suffer more diseases than one who leads a healthier life.
The PH
pH is the degree of acidity of the body. To achieve an adequate pH, it is necessary to avoid stress, exercise and suppress bad habits, in addition to increasing the consumption of foods such as lemon, garlic, raisins, watermelon, papaya, broccoli or parsley, among others. Inadequate pH can directly harm your immune system.
In this other article from we explain how to measure the pH of the body.
Genetics
Hereditary genetic diseases are those in which the altered gene causing the disorder is found in germline gametes. So, if you're wondering why we get sick, you should keep in mind that there is a long list of diseases that can be inherited from generation to generation, some of the most common being cystic fibrosis, thalassemia, fragile X syndrome, Huntington's disease, Marfan syndrome, etc.
How to strengthen the immune system so as not to get sick
There are diseases that are practically impossible to avoid, however, some of the most common (colds, flu, obesity, stomach problems, etc.) can often be avoided by strengthening the immune system. Here are some of the things you can do:
