Cold weather 'may raise risk of elderly stroke'
Low temperatures during winter could result in the rise of high blood pressure cases in elderly people, a new study has revealed.
The study, carried out by the Institute of Health and Medical Research in Paris, analysed over 8,800 men and women aged 65 or older, with the participants being drawn from three cities in France.
Authors of the report wrote: "Although our study does not demonstrate a causal link between blood pressure and external temperature, the observed relationship nevertheless has potentially important consequences for blood pressure management in the elderly."
Such risks which could be exacerbated by high blood pressure include a heightened chance of suffering a stroke, heart attack or kidney failure.
Doctors said they were unaware as to why this may be the case, although they proposed that a hormone linked to stress which is naturally released in cold weather may raise blood pressure due to its heart-speeding qualities.
According to Bupa, high blood pressure affects up to three in ten people.
