If you’re hiking or vigorously exercising and wilting, stop now.
And if you have a job out in the sun, move it indoors or to a cooler time.
The Center for Health Protection (CHP) is putting out these reminders in case we have not heard about Hong Kong’s blistering summer or experienced it.
“The public should carry and drink plenty of water to prevent dehydration while engaging in outdoor activities,” a CHP spokesman 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,” he said.
“The obese, the sick, including those with heart disease or high blood pressure, the old and the young are more vulnerable to heat-related illnesses. They should pay special attention.”
Here are more things you can do:
1) Wear loose and light-coloured clothing to reduce heat absorption and facilitate sweat evaporation and heat dissipation;
2) Avoid vigorous exercise and prolonged activities like hiking or trekking as heat, sweating and exhaustion place additional demands on your physique;
3) Perform outdoor activities in the morning or late afternoon;
4) For indoor activities, open all windows, use a fan or use air-conditioning to maintain good ventilation; and
5) Reschedule work to cooler times of the day.
If working in a hot environment can’t be avoided, the people should put shade in the workplace where practicable and start work slowly, picking up gradually. Get into a cool area for rest at regular intervals to allow the body to recuperate.
1) Minimise direct exposure of the skin and the eyes to sunlight;
2) Wear loose long-sleeved clothing made of close-woven fabrics;
3) Wear a wide brim hat or use an umbrella;
4) Seek a shaded area or put on UV blocking sunglasses; and
5) Apply a broad-spectrum sunscreen lotion with a sun protection factor of 15 or above. Apply liberally and reapply after swimming or sweating.
Anyone feeling unwell should stop exercising immediately and seek medical advice as soon as possible.
