Relationships between the Attack of Raynaud's Phenomenon in Female Students and Winter Weather

Abstract

To clarify the relationship between the occurrence of the attacks of Raynaud's phenomenon and weather, maximum, minimum and mean air temperatures in winter were surveyed on the days in which the attacks of Raynaud's phenomenon occurred in 4 female students with Raynaud's phenomenon in the fingers. The results obtained were as follows:
1) In general, the percentages of the days when the attacks of Raynaud's phenomenon occurred was the highest from the end of November to December, compared to the January and February results.
2) Minimum and mean air temperatures on the days excluding holidays when the attacks of Raynaud's phenomenon occurred were significantly lower than those on the days when the attacks did not occur for the subject who went to school from her own home; this result was not noticeble for the others who lived at the dormitory. In all subjects there were no differences in the maximum air temperatures between the days when the attacks of Raynaud's phenomenon occurred and the days when the attack did not occur.
