In Kneipp's time, everyday life was very different from today. Not only was almost the entire human existence inextricably linked to the pursuit of "earning a living"; in addition, at the beginning of the industrial revolution, physical work usually meant hard labor due to the lack of technical aids.
Accordingly, very few people thought about conscious rest periods, let alone mindfulness, self-care & Co. - which did not stop Sebastian Kneipp from pointing out the importance of a sensible life order. After all, he was convinced that a healthy body (which was not least the livelihood of the hard-working population) and mental balance can only be achieved through a balanced lifestyle.
