In a high-temperature environment, excessive sweating and difficulty in heat dissipation can cause stress to the body. Members of the public should take the following precautions:

Hydrate in a timely manner to prevent dehydration;

Wear light-coloured, loose-fitting and breathable clothing to minimise heat absorption and facilitate perspiration and heat dissipation;

Keep the room well ventilated, e.g. by opening windows;

Avoid strenuous exercise and prolonged activities such as hiking or trekking;

Arrange outdoor activities in the morning or the late afternoon, if possible, and bring enough water; and

Avoid beverages containing caffeine, such as coffee and tea, as well as alcoholic beverages, which may speed up water loss through the urinary system.

In addition, infants and children, the elderly, pregnant women, individuals with chronic illnesses such as heart disease or high blood pressure, outdoor/manual workers, and overweight people are more susceptible to heat stroke. These groups should pay special attention to the following:

Avoid taking infants and young children outside when the temperature is high. If they must go outside, adults should ensure they stay in places with moderate temperatures and good ventilation or air-conditioning. Infants and young children should never be left unattended in a confined space such as a vehicle;

The elderly, pregnant women, individuals with chronic illnesses or overweight people should pay close attention to their health. They should seek help as soon as possible if they experience any abnormalities in health indicators such as blood pressure, heart rate, etc or if there are fluctuations in their health conditions. Avoid going out when the temperature is high. Make sure there is good ventilation, or turn on a fan or air-conditioner to keep an appropriate temperature indoors. High temperatures can also worsen the condition of people with chronic illnesses (such as cardiovascular and respiratory diseases). Therefore, they should have an ample supply of their usual medication and keep in contact with family members, neighbours and the community. People should seek immediate help if they feel unwell.

Outdoor/manual workers are advised to reschedule work to cooler hours as far as feasible. If working in a hot environment is unavoidable, provide shade where practicable and use ventilation and heat dissipation equipment. Once work has begun, gradually adjust the pace of work and take breaks in the shade to regain strength.

"Heat stroke is one of the most common health risks in hot weather. Over the past five years, there have been over 200 hospital admissions due to heat stroke each year in Hong Kong, with two to five fatal cases occurring mainly during the summer months from May to September. Vulnerable groups are more susceptible to heat stroke. Symptoms include dizziness, headache, nausea, shortness of breath or confusion. In severe cases, patients may suffer from convulsions or become unconscious, which can be life-threatening if they are not cooled down and resuscitated in a timely manner," said the Controller of the CHP, Dr Edwin Tsui.

Members of the public are also advised to pay attention to the latest weather, as well as the real-time and forecasted ultraviolet (UV) index released by the Hong Kong Observatory (HKO). When the UV index is high (6 or above):

Minimise direct sunlight exposure to the skin and the eyes;

Apply broad-spectrum, water-resistant sunscreen with a sun protection factor (SPF) of at least 30 or higher when participating in outdoor activities. Reapply sunscreen every two hours if staying outdoors for long periods of time, or after swimming, sweating or toweling off;

While using DEET-containing insect repellents for personal protection against mosquito-borne diseases, apply sunscreen before insect repellent;

Seek shade;

Wear UV-blocking sunglasses;

Wear loose-fitting clothing with long-sleeves; 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.

The public may obtain more information from the DH's Health Education Infoline (2833 0111), heat strokepage andUV radiation page; the HKO's Dial-a-Weather (1878 200),latestweather report and forecast, UV Indexand weather information for hiking and mountaineering; and press releases of the Labour Departmenton precautions against heat stroke for outdoor workers and their employers when the Heat Stress at Work Warning is in force.

Customs YES organises Shenzhen Qianhai Youth Entrepreneurship Exploration Day

Customs YES organised the Customs YES X QMN Shenzhen Qianhai Youth Entrepreneurship Exploration Day in collaboration with the partnering organisation Quality Management Network (QMN) today (January 17). Led by the Assistant Commissioner (Administration and Human Resource Development) of Customs and Excise, Ms Phoebe Wong, a delegation of 51 youth from Customs YES and QMN visited innovation and technology (I&T) companies and a start-up incubation base in Qianhai, Shenzhen, to gain insights into the latest developments in the low-altitude economy and explore youth entrepreneurship opportunities in the Greater Bay Area.

The delegation first visited a Drone Education Experience Centre in Shenzhen to learn about the latest developments in aerial photography technology, including its applications in power system inspection and emergency rescue. In addition, under the guidance of professional instructors, the participants took part in a robotics competition and experienced drone operation.

The delegation then visited the Qianhai Shenzhen-Hong Kong Innovation and Entrepreneur Hub, where they learned about various facilitation measures supporting Hong Kong and Macao youth in pursuing entrepreneurship and career development on the Chinese Mainland. The participants also interacted with representatives of Hong Kong I&T start-up enterprises based at the hub to learn more about the latest developments in the low-altitude economy, and visited the Hong Kong Youth Short-Term Apartments which offers one-stop accommodation services for Hong Kong youth.
