A link between the weather and strokes? New research suggests there is. Higher rates of hospital stays for stroke were tied to certain kinds of weather conditions:
COLD WEATHER: The risk fell as the temperatures went up. The chances of being hospitalized for a stroke fell 3 percent for every 5-degree rise in temperature.
HUMIDITY: Each 5-degree rise in the dew point (humidity) raised the risk by 2 percent.
TEMPERATURE CHANGES: Big changes over one day made a difference. Each 5-degree increase in daily temperature fluctuation raised the chance of stroke hospitalization by 6 percent.
