CHP reminds public on precautions against heat stroke during very hot weather
The Centre for Health Protection (CHP) of the Department of Health (DH) today (October 1) reminded members of the public, particularly those undertaking outdoor activities, to take heed of necessary measures against heat stroke and sunburn in very hot weather.
"The public should carry and drink plenty of water to prevent dehydration while engaging in outdoor activities," a spokesman for the CHP said.
"Those engaged in strenuous outdoor activities should avoid beverages containing caffeine, such as coffee and tea, as well as alcohol, as they speed up water loss through the urinary system," the spokesman explained.
"Infants and children, the elderly, pregnant women, those with chronic illnesses such as heart disease or high blood pressure, outdoor/manual workers, and individuals who are overweight are more vulnerable to heat stroke. They should pay special attention," the spokesman added.
The public should adopt the following precautions:
Wear loose and light-coloured clothing to reduce heat absorption and facilitate sweat evaporation and heat dissipation;
Avoid vigorous exercise and prolonged activities like hiking or trekking as heat, sweating and exhaustion can place additional demands on the physique;
Perform outdoor activities in the morning or the late afternoon, if possible;
For indoor activities, open all windows, use a fan or use air-conditioning to maintain good ventilation;
Do not stay inside a parked vehicle; and
Reschedule work to cooler times of the day if feasible. If working in a hot environment is inevitable, introduce shade in the workplace where practicable. Start work slowly and pick up the pace gradually. Move to a cool area for rest at regular intervals to allow the body to recuperate.
The public should also note the latest and the forecast Ultraviolet (UV) Index released by the Hong Kong Observatory (HKO). When the UV Index is high (6 or above):
Minimise direct exposure of the skin and the eyes to sunlight;
Wear long-sleeved and loose-fitting clothes;
Wear a wide-brimmed hat or use an umbrella;
Seek a shaded area or put on UV-blocking sunglasses;
Apply a broad-spectrum sunscreen lotion with a minimum sun protection factor (SPF) of 15, preferably higher. Reapply every two hours if you stay out in the sun, and after swimming, sweating or towelling off; and
While using DEET-containing insect repellents for personal protection against mosquito-borne diseases, apply sunscreen first, then insect repellent.
If symptoms develop, such as dizziness, headache, nausea, shortness of breath or confusion, rest and seek help immediately, and seek medical advice as soon as possible.

"Celebration of National Day - The Next Generation Chorus Performance" drone show cancelled
Before the start of "Celebration of National Day - The Next Generation Chorus Performance" yesterday (September 30) evening, the implementing organisation expressed that the signal of the drones were seriously interfered, making the drones unable to position accurately. After investigation, it is believed to be related to meteorological factor; human factor was not involved. All related parties immediately tried their best to recover the situation, in the hope that the drone show could continue. The master of ceremony introduced the programmes and announced the updated situation at 8.38pm, 8.46pm and 9.06pm. As the signal showed no improvement, the drone show had to be cancelled. Contingency plan was adopted and pre-recorded footage was broadcast on television.
We sincerely apologise for keeping all guests, performing students and groups, and audience both on site and in front of their televisions waiting during the repair attempts.
