In a reminder issued on August 28, 2026, the Centre for Health Protection (CHP) of Hong Kong's Department of Health urged the public to take precautions against heat-related illnesses, including heat cramps, heat exhaustion and heat stroke. It advised timely hydration, light-coloured loose clothing, well-ventilated indoor spaces, and avoiding strenuous exercise or prolonged activities such as hiking. Outdoor activities should be scheduled for the morning or late afternoon where possible, and caffeine and alcohol avoided because they may speed water loss.

The CHP said infants and young children, the elderly, pregnant women, people with chronic illnesses, overweight people and outdoor or manual workers are more susceptible to heat stroke. Infants and young children should never be left unattended in a confined space such as a vehicle. The elderly and others at risk were advised to monitor health indicators and keep in contact with family, neighbours and the community, while outdoor and manual workers were urged to reschedule work to cooler hours where feasible and take breaks in shade.

Citing over the past five years, the CHP said Hong Kong has recorded more than 200 hospital admissions due to heat stroke each year, with two to five fatal cases occurring mainly from May to September. It also advised attention to the Hong Kong Observatory's real-time and forecast UV index, noting precautions when the index reaches 6 or above.
