Health retreats, like Intermittent Living Journey

build up from the Intermittent Living® concept, developed by Dr Leo Pruimboom, PNI Europe. This concept is based on the scientific knowledge of PsychoNeuroImmunology, PNI. It includes a great health retreat and detoxification.

How to start and stay with a healthy lifestyle?

Which aspects of a lifestyle treatment plan ensure that someone maintains healthy behavior? The straightforward answer to this is: experience yourself what it does for your health when you adjust your behavior.

Tale charge in preventing and curing illness, it starts with you. 

Intermittent living®

Intermittent Living® can prevent and cure illness and complaints. But you can only truly grasp the positive effects of this method when you submerge yourself for a while in an intermittent lifestyle.

By applying this way of life to your current lifestyle, you will be and stay fit and healthy, despite our hectic everyday lives. Through an intermittent living® week, you can live and learn in a unique way what this scientifically proven healthy lifestyle can do for you.

Health issues often originate from earlier periods in our life, sometimes even from before you were born, meaning the developmental period in the womb. However, the symptoms usually only manifest themselves later in life, as many symptoms lay dormant for long period of time. If, in the course of your life, you realize that it is good or even necessary for you to turn the tide, it may be now or never.

Intermittent Living® week

Under the guidance of certified Intermittent Living® coach, you, as a client, patient or employee, will receive  an intensive training of five to six days to take out the elements that prevent you from living a healthy life, such as old familiar stress factors that characterize modern life.

During this intensive training your body remembers how it should react to old stimuli (temperature, elevation, food and water restriction, infections …..). This will strengthen your immune system. The result: health and resilience. To make sure that you reset all the basic systems in your body, namely your immune, neurological and psychological systems a minimum of five to six days in necessary.  This journey is for your own health. You will get all the knowledge that you need, deep learning.
