| Research Abstract |
The purpose of this study is to examine the relationship of lifestyle and stress of preschool children. The marker for the stress was the secretory-Immunogloblin A (s-IgA) in saliva. Subjects were 175 preschool children aged 4 to 5 years. The following results were obtained. The circadian rhythm of the s-IgA was found. The s-IgA showed the highest level just after wakeup. The children who sleep earlier and wake up earlier have higher s-IgA than the children who sleep and wake up later. It was suggested that the lifestyle of early bedtime and early wakeup is effective for reducing the stress and improving the immunity in preschool children, by the s-IgA marker.
