Although typically associated with outdoor exposure or cold-water submersion, hypothermia may occur indoors and in hospitalised patients. Advise at-risk patients not to underestimate the effects of cold temperatures. At-risk patients should dress appropriately for weather conditions, stay dry, avoid windy conditions, and avoid drinking alcohol or overexertion in very cold weather. Homes containing older people, infants, or anyone else at risk of hypothermia should set their thermostat to an appropriate level at all times. People submerged in cold water should only attempt to swim when close to a boat or near the shore, to conserve energy. CDC: prevent hypothermia and frostbite Opens in new window
Active pre-warming of patients for at least 30 minutes before general anaesthesia is recommended to prevent hypothermia.[18][19]
