Juan-Carlos Lerman, a researcher at the University of Arizona, examined the relationship between our physical work and rest. What Lerman’s scientific research demonstrated was that the average human being needs one day of rest per seven days to function properly. Lerman’s research is summarized by Marva Dawn: “According to Lerman’s theory, failing to rest after six days of steady work will lead to insomnia or sleepiness, hormonal imbalances, fatigue, irritability, organ stress, and other increasingly serious physical and mental symptoms.”32
