Why is proper hydration vital for our immune system?

Hydration is a key factor for the proper functioning of the immune system. More specifically, water is involved in several biological processes that support our natural defenses.
Transporting immune cells and nutrients

Water plays a key role in transporting immune cells and nutrients throughout the body. This allows defense cells to circulate easily and quickly reach the areas where they are needed to fight infections.

It is important to understand that if the body is well hydrated, blood and lymphatic circulation remains optimal. Hydration therefore ensures that our immune system functions at full capacity.

Maintaining Mucous Membrane Balance

Mucous membranes are membranes located in key areas of our body, such as the throat, lungs, and intestines. These mucous membranes act as a barrier against infections, as they are often the first to come into contact with external pathogens such as viruses and bacteria.

As long as the body remains well hydrated, these membranes remain moist and healthy. This environment strengthens their ability to prevent microbes from entering the body.

Detoxify the Body

One of the key functions of water is to facilitate the elimination of waste and toxins produced by the body's metabolism. The kidneys, intestines, and skin use water to eliminate these unwanted substances through urine, feces, and perspiration.

An immune system overloaded with toxins and waste will have a harder time responding to infections since it must also process this overload. In fact, hydration helps maintain detoxification functions by allowing the organs to efficiently eliminate these toxins.
