The relationship of seasons and blood pressure was investigated. The individuals in the sample groups were of two types: normal individuals and individuals who have been diagnosed as hypertensives and under medical supervision. This was a seasonal study? measurements were taken during midsummer and early fall, 1979. Factors constituting the variable for individual differences included: sex, age, genetic factors, diet, general body build and managerial vs, laborer workload.

Individual differences were controlled by use of a randomized complete block design with each individual constituting a block. Season was the treatment factor, and individual was the blocking factor. Measurements were taken daily during the same time period on each working day over a six-week period in each season.

The results indicated that the average diastolic blood pressure was significantly higher in the summer than in the fall. The systolic pressure showed no differences in regard to seasons studied.
