In a series of studies of the workload of lotus growers and their health condition, we checked up on the results of group health screening of lotus growers in comparison with those of other farmers among Tsuchiura agricultural cooperative members in 1992. During that year, we also carried out a time study of lotus cultiration from planting through harvesting. In 1993, we investigated the lifestyle and behavioral pattern of lotus growers. In 1994, an index of cummulative fatigue symptoms was made for lotus growers and loads exerted on their circulatory system were examined.
These studies brought to light hard facts about lotus growing. The farmers have to work in muddy fields laboriously, and for many hours at that, planting in the hottest season and harvesting in the coldest season for many hours. Even when they feel ill, they cannot afford to leave toiling off for their health. We found many signs and symptoms of physical disorder resulting from overwork and peculiar to lotus growing. To improve the working conditions of lotus growing, we recommended the use of the lotus center as a labor saving mode of work so as to facilitate the introduction of power harvesters or the use of greenhouses.
Although there are many socioeconomic issues such as aging of the farming populace, lack of successors and decline in agricultural economy, we will continue to make efforts at health control to protect the health and welfare of farmers by accumulating our knowlege through studies of the state of lotus farming and the health condition of the lotus farmers in other areas as well.
