Abstract

There is increasing interest in the effects of meteorological factors on stroke occurrence. A number of studies have found that cold exposure was a trigger to the onset of cerebral infarction in winter. It was believed that the case of stroke occurrence on warm days in winterwas just a coincidence and negligible. The main objective of this study was to offer the evidence against the above belief. We aimed to find typical patterns among stroke occurrences in case the weather became warmer in winter. Associations analysis was conducted using daily data of emergency transport at Nagoya City in Japan. Typical patterns were identified among risky stroke occurrences even for the case that the weather became warmer in winter. These findings will contribute to an accurate forecast of stroke occurrence in winter.
