SEOUL, Sept. 22 (Korea Bizwire) – Research shows that with the daily temperature range of Asian countries standing around 10 degrees Celsius, the death rate has increased by a factor of 2.6.
A research team led by Professor Kim Ho from the Graduate School of Public Health at Seoul National University analyzed data on deaths between 1979 and 2010, and meteorological data from 30 cities in four Asian countries (Korea, China, Japan and Taiwan). The death rates of each country were compared to the daily temperature ranges.
The researchers discovered that as the temperature difference increases by one degree Celsius, the total death rate, death rate from circulatory diseases and the death rate from respiratory diseases increased 0.58 percent, 0.81 percent and 0.90 percent each. Just considering Seoul, the rates showed a 0.68 percent, 0.30 percent and 1.07 percent increase respectively.
Of note, a large difference in temperature influenced the increase in death rates greatly. Incheon showed the highest death rate from respiratory diseases among the 30 cities. The death rate increased 2.84 percent when the daily temperature rate increased one degree (Celsius).
The influence of the daily temperature range was even greater among the elderly aged over 65. Also, among the 30 cities, those located in the East reported greater daily temperature variation, which lead to a greater influence of temperature range changes on death rates.

Professor Kim Ho explained the influence of temperature on the human body. “As the daily temperature variation increases, heart rate and blood pressure as well as the immune system and respiratory system are influenced more. The rapid change in external temperatures could affect immune mechanisms in the body.”
In conclusion, during periods when the daily temperature differs greatly, one has to be extra careful not to lower immunity. Heavy drinking and smoking should be minimized. The elderly and those who have hardening of their arteries, hyperlipidemia, diabetes, and high blood pressure should be extra careful of sanitation and hygiene when going out.
Also, to boost the immune system, taking vitamins and nutrients is important, and drinking water to stay hydrated is crucial.
