This study determined if variations in upper-limb arm size, volume or fluid distribution occur in response to heat and humidity as it varies with the seasons in healthy females. Data collection took place in spring, summer and winter with results showing significant relationship between seasonal climate variation and limb size, with significant decreases in summer and winter when compared to spring. There was no relationship between seasonal climate variation and limb volume or fluid distribution. This study has described normal variation in limb size with seasonal change in a tropical environment. This provides baseline data for future research comparing the effect of seasonal change in at-risk populations, such as those with lymphoedema and vascular conditions.
