Currently, on social networks, information is spreading: "For every 1 degree Celsius increase, the risk of stroke increases by 10%".
BSCKII. Nguyen Tien Dung - Deputy Director of the Stroke Center, Bach Mai Hospital affirmed: No official research by the World Stroke Organization (WSO), the World Health Organization (WHO) or reputable medical associations has given such an accurate and simple ratio (1°C = 10%) to describe the link between temperature and stroke risk.
The risk of stroke depends on many complex factors: Personal history of illness (stroke, cardiovascular disease, blood pressure, diabetes...), age, current health status, activity level, access to cool places, dehydration, adherence to treatment, other environmental factors (umidity, air pollution), exposure time to high temperatures... It is impossible to limit a simple formula based only on temperature.
Studies have shown a real link, not a fixed ratio: Many epidemiological studies (such as some cited by the WHO on the effects of climate change on health) confirm that extreme heat waves significantly increase hospitalization and death rates from cardiovascular diseases, including stroke, especially in vulnerable groups. However, this increase is uneven and cannot be given a fixed percentage for each increase in heat.
The doctor affirmed that this information is confusing and confusing unnecessarily: Providing a sensational but unfounded number does not help prevention, but only causes excessive confusion and anxiety for the community, especially the patient.
Bach Mai Hospital recommends: People need to be alert, search for information from official sources: websites of the Ministry of Health, major hospitals, the World Health Organization (WHO), the World Stroke Organization (WSO) and prestigious medical associations.
