Water & Cardiovascular Health: why good hydration keeps your heart system performing

Thomas Freitag10 minutes

A well-functioning cardiovascular system is the basis for energy and resilience. One of the simplest levers is often overlooked: water in the right quality.

A well-functioning cardiovascular system is the basis for energy and resilience. One of the simplest levers is often overlooked: water in the right quality.

Water and blood: a close relationship

Blood consists of roughly 90 percent water. It transports oxygen, nutrients and hormones - and removes metabolic waste. Good hydration keeps blood at optimal viscosity: too thick means the heart works harder. Sufficient water keeps the system flowing smoothly.

Blood pressure and hydration

Fluid deficit reduces blood volume - the heart must pump more frequently to maintain pressure. Electrolytes play a key role: potassium, magnesium and sodium regulate fluid balance and vascular tone.

Honest assessment: Water alone does not regulate blood pressure - it is one building block alongside nutrition, movement and stress management.

Water quality for the cardiovascular system

Water typeConductivityFor metabolism
German tap water480-700 uSBus nearly full
Plose, Lauretana, Voss20-80 uSGood
Trink Dich Fit station10-50 uSOptimal - all 3 Vincent parameters
Omega-3 fatty acids

Support healthy blood lipids and vascular flexibility. In: oily fish, linseed oil, walnuts.

Potassium & Magnesium

Regulate fluid balance and blood pressure. In: bananas, potatoes, nuts, green vegetables.

Antioxidants

Protect blood vessels from oxidative stress. In: berries, dark chocolate, green tea, OPC.

The EIGW.org 7-Step Programme

The EIGW.org 7-Step Programme for greater physical performance: Ideal Water (1) - Movement (2) - De-acidification (3) - Detoxification (4) - Nutrition: potassium, magnesium, omega-3 (5) - Regeneration (6) - Targeted Performance Optimisation (7). The SYN-ART movement connects people living this programme together.

Don't believe us - check for yourself

Tea test

Brew black tea with tap water and ideal water - tap water often shows an oily film.

Flower test

Same flowers in two vases - observe how long each stays fresh.

Animal test

A second bowl with ideal water next to the usual one - the animal chooses freely.

Window test

Clean a window with only ideal water - often dries streak-free due to low conductivity.

Frequently asked questions

Does water lower blood pressure?

Good hydration supports stable blood pressure - alongside nutrition, movement and medical care. Water alone does not regulate blood pressure.

How much water is good for the heart?

Around 1.5 to 2 litres daily, more with sport or heat. Regularly spread throughout the day.

Your next steps

Knowledge is the first step - implementation is the second.

Trink Dich Fit is a programme of EIGW. For the hardware of our Trink Dich Fit water stations we work with Ideal Water as implementation partner.
