Hong Kong health authorities reminded residents Saturday to take measures against cold weather, particularly the elderly, people with chronic illnesses, outdoor workers, pregnant women, infants and children.
The Centre for Health Protection of the Department of Health issued the advisory, noting that colder temperatures can pose greater risks to vulnerable groups.
A spokesman for the center said elderly people generally have less insulating fat and weaker body temperature regulation, while chronic conditions such as hypertension, diabetes, respiratory illnesses or cardiovascular disease can reduce heat generation and increase the chance of complications.
The center recommended that the elderly and those with chronic illnesses wear warm clothing including hats, scarves, gloves and socks; eat sufficient calories; exercise regularly; avoid prolonged outdoor exposure especially in early morning or at night; use heaters cautiously with proper ventilation; and avoid alcohol, which can accelerate heat loss.
For infants, children and pregnant women, the advisory urged parents to dress babies warmly but lightly to prevent overheating, change clothing promptly if it becomes wet, and avoid outdoor activity during colder parts of the day.
Safety tips for putting children to bed included keeping rooms well-ventilated at a comfortable temperature, placing babies on their backs with heads and arms uncovered, using firm mattresses without pillows or loose bedding, and maintaining a smoke-free environment.
Outdoor workers were advised to monitor weather reports, wear appropriate warm clothing, change out of wet garments quickly and take breaks if feeling unwell, especially when a Cold Weather Warning is in effect.
The center also highlighted increased winter activity of respiratory pathogens including influenza and COVID-19, recommending seasonal influenza vaccination for everyone aged 6 months and older, with priority for high-risk groups. It urged elderly residents, particularly those in care homes, to receive both influenza and COVID-19 vaccines plus boosters as recommended.
Additional guidance covered personal and environmental hygiene to prevent respiratory illnesses, safe hotpot practices to avoid food-borne diseases, and proper ventilation when using fuel-burning appliances to prevent carbon monoxide poisoning.
