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 (June 9) 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;
Apply a broad-spectrum water-resistant sunscreen product with a sun protection factor (SPF) of at least 30 or higher when participating in outdoor activities. Reapply every two hours if you need to stay outdoors for a prolonged period, or after swimming, sweating or towelling off;
While using DEET-containing insect repellents for personal protection against mosquito-borne diseases, apply sunscreen first, then insect repellent;
Seek shade;
Wear UV-blocking sunglasses;
Wear long-sleeved and loose-fitting clothes; and
Wear a wide-brimmed hat or use an umbrella.
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.

Health risk category for Air Quality Health Index has reached "Serious" level
The Environmental Protection Department (EPD) has recorded higher than normal pollution levels today (January 13). At 5pm, the Air Quality Health Index (AQHI) at theTuen Mungeneral monitoring station reached 10+, corresponding to the "Serious" health risk category.
Winds are weak over Hong Kong today, which is unfavourable for pollutant dispersion. The intense sunshine enhances photochemical smog activity, leading to the rapid formation of ozone and fine particulates in the Pearl River Delta region. The high ozone level also promotes the formation of nitrogen dioxide.
According to the Hong Kong Observatory,amoderate easterly airstream is expected to affect the coast of Guangdong gradually tomorrow. It is expected that pollution levels will remain higher than normal until then.
With a health risk category in the "Very High" range or above, children, the elderly and persons with existing heart or respiratory illnesses are advised to reduce physical exertion and outdoor activities to a minimum or avoid such activities. The general public is advised to reduce, or reduce to a minimum, outdoor physical exertion, and to reduce time outdoors, especially in areas with heavy traffic. As health effects of air pollutants may vary for individuals, persons who are in doubt or experience discomfort should seek advice from healthcare professionals. The public may visit the Centre for Health Protection's website (www.chp.gov.hk/en/content/9/460/3557.html) for more information on health effects of air pollution and relevant health advice.
The Education Bureau (EDB) urges all schools to visit the EDB website for appropriate measures to safeguard students' health and take note of changes in the index. The relevant hyperlink is as follows: www.edb.gov.hk/en/sch-admin/admin/about-activities/sch-activities-guidelines/index.html.
When the AQHI is at the "Very High" level, employers of outdoor workers performing heavy manual work are advised to assess the risk of outdoor work and take appropriate preventive measures to protect the health of their employees, such as reducing outdoor physical exertion and the time of their stay outdoors, especially in areas with heavy traffic. At the "Serious" level, employers of all outdoor workers are advised to assess the risk of outdoor work and take appropriate preventive measures to protect the health of their employees.
Members of the public can check the current AQHI readings at the EPD's website (www.aqhi.gov.hk/en.html) or by calling the hotline 2827 8541.
