Energy means life and is therefore indispensable for people and the environment. But why is it sometimes so difficult to direct one's own energy in the right direction? And why do so many people allow themselves to be unnecessarily deprived of energy so often? Nathalie Schmidt has intensively studied the connection between energy and life as part of her professional work. In this second basic volume, she sheds particular light on the phases of life in which people have an increased need for energy and shows ways to prevent a loss of energy and replenish energy reserves. Examples from everyday life illustrate what an enormous difference it makes whether a day is spent with a lot of energy or with little. The author also does not shy away from addressing the connection between a lack of energy and diseases, as well as explaining which energetic processes take place in the body.
