The Department of Health has warned people, particularly those having outdoor activities this afternoon or during the weekend, to take necessary measures to prevent heatstroke and sunburn.
The warning came as today's (August 3) temperature soared to 35 degrees Celsius.
The Assistant Director of Health (Health Promotion), Dr Regina Ching, said people should make sure that they take and drink plenty of water to prevent dehydration while engaging in outdoor activities.
She said that people engaging in strenuous outdoor activities should avoid beverages containing caffeine (such as coffee and tea) and alcohol, since these substances would speed up water loss from the body through the urinary system.
¡§Particular attention should be paid to children, the elderly, the sick (including those with heart disease and high blood pressure) and obese persons who are more vulnerable to heat-related illnesses," Dr Ching said.
When going outdoors, consider the following protective measures:
* Wear light-coloured loose clothing to reduce heat absorption and facilitate sweat evaporation and heat dissipation.
* Do not engage in prolonged activities such as hiking or trekking under extremely hot weather, as the heat, sweating and exhaustion put additional demands on one¡¦s physique.
* Choose to perform outdoor activities in the morning or late afternoon.
* Re-schedule your work to cooler times of the day. If you must work in a hot environment, introduce shading in the work areas where practicable, then start slowly and pick up the pace gradually. Get into a cool area for a rest every now and then to let your body recuperate.
* Take heed of the measured and forecast UV index released by the Hong Kong Observatory. When the UV index is high (6 or above), people should consider wearing long sleeved clothing made from close woven fabric, a wide-brim hat or using an umbrella, seeking shade, putting on UV blocking sun-glasses and applying sunscreen with a protection factor of 15 or above. The above precautions should be reinforced for higher levels of the UV index.
* If you choose to perform exercise indoors, make sure that indoor ventilation is adequate.
Dr Ching said that any person feeling unwell should stop immediately and seek medical advice as soon as possible.
