NSW Health is warning people to be aware of the risk of hypothermia. With the recent cold weather overnight, there has been a marked increase in the number of people, especially older people being taken to hospital after developing the condition.
Hypothermia occurs when a person’s body temperature falls below 35°C. It is an extremely serious condition and may, in some cases, be fatal.
Dr Richard Broome, Medical Epidemiologist, NSW Health said 19 people, mostly elderly, had been brought to hospital with hypothermia over the last week.
"Elderly people are more susceptible to hypothermia, as the body’s ability to endure periods of exposure to the cold is reduced," Dr Broome said.
"People should dress warmly, not only when they go outdoors but also when they are inside and it is cool, especially at night when the temperature drops.
"It is important people are aware of the signs and symptoms of hypothermia, particularly in the elderly who can be most vulnerable to this condition. One of the first symptoms of hypothermia is confusion – so the person may not recognise that something is wrong," said Dr Broome.
Signs of hypothermia include:
Signs of severe hypothermia include confusion, slurred speech, progressive loss of consciousness, weak pulse and shallow breathing.
A person’s natural temperature should be between 36.5°C to 37.5°C. If a person’s temperature is below 35°C, call for emergency help. While you are waiting, keep the person warm and dry by wrapping them in blankets, towels or coats.
"Throughout winter, it is important to keep an eye on elderly neighbours or elderly family members who live alone. Elderly people, especially those who live alone, should consider wearing a Personal Emergency Response System (PERS)," Dr Broome added.
A PERS is a device that is worn as a pendent and, when activated, signals for help from a local care provider.
