The effect of environmental temperature on stroke occurrence in a subtropical climate was studied over a 1-year period by documenting the number of strokes (subdivided into cerebral infarct and intracerebral hemorrhage) admitted into a district hospital in Hong Kong at different temperatures. There was no significant correlation between the number of strokes (or its subtypes) per day per temperature category and the environmental minimum or maximum temperature. However, an association was present between the occurrence of cerebral infarcts and maximum temperature on the day of onset in elderly patients aged 70 years and above. Environmental temperature is not a strong risk factor for the occurrence of stroke in a subtropical climate.
通过记录香港一家地区医院在不同温度下收治的中风病例数（细分为脑梗死和脑出血），对亚热带气候下环境温度对中风发生的影响进行了为期1年的研究。每天每温度类别下的中风病例数（或其亚型）与环境最低或最高温度之间无显著相关性。然而，70岁及以上老年患者的脑梗死发生与发病当天的最高温度之间存在关联。在亚热带气候下，环境温度并非中风发生的强风险因素。
