Water in the human body:

20-25% bone,
85-90% blood,
75-80% of muscles,
75-80% of the brain,
80-85% of the heart.

Functions of water in the human body:


is responsible for the proper course of metabolic processes.
takes part in the removal of metabolic by products (including toxins).
transports, dissolves and facilitates the absorption of nutrients.
occurs in all cells, organs, tissues and body fluids (it is the basic building block of the body).
is responsible for regulating body temperature, pressure and pH.

takes part in the transport of oxygen.
it is a component of blood and enables the transport of the components contained in it.
improves concentration and mental abilities, adds energy.
makes muscles and joints more flexible.
has an impact on the condition of the skin.

Factors influencing the amount of water needed the body:


physical activity,
living environment,
individual needs of the body,


The demand for water is increasing:


in people who train,
in women during pregnancy and breastfeeding,
in people exposed to high or low temperatures,
in sick people,
in people consuming large amounts of fiber (fiber binds water in the digestive tract).

Types of water:


Naturally mineral water
contains at least 1000 mg of minerals per liter.


Healing water

they contain from 2,000 mg to even 24,000 mg of minerals per liter.


Spring water

has less than 1000 mg of minerals per liter,
it is not suitable for supplementing bioelement deficiencies.


Table water

adding water rich in minerals or mineral salts to spring water.
Contains over 1500 mg of minerals per liter.

Type of mineral water:

Very low mineralised waters
contain less than 50 mg of dissolved minerals per liter

Low mineralised waters

they contain 51- 500 mg of dissolved minerals per liter

Moderately mineralised waters

containing from 501 to 1500 mg of dissolved minerals per liter

Highly mineralised waters

contain more than 1501 mg of dissolved minerals per liter

You should consume 30- 50 milliliters of water per 1 kg of body weight.
