Immunity is the innate ability of the body to resist hostile external influences, and above all, viruses and bacteria. Without immunity, man could not exist. Immunity is provided by various components. First of all, these are lymphocytes and leukocytes, as well as phagocytes that absorb foreign microorganisms. In addition, a significant role in immunity is played by human skin and mucous membranes, which produce substances that kill germs.
Immunity is not always permanent – due to various reasons, it can weaken, and then the body will become an easy target for various diseases.

Signs of low immunity include:

Weak immunity hits almost any system of the body and can even be fatal if it is not specifically targeted to strengthen it.
The lack of immunity may be due to different reasons:
- chronic stress
- hereditary factors
