Elderly persons, pregnant women, infants and children, those with chronic illnesses, such as heart disease or high blood pressure, as well as the obese are more vulnerable to heat stroke. Watch out for any symptoms of heat stroke.
When engaged in work under hot weather or high-temperature environments, please refer to the Guidance Notes on Prevention of Heat Stroke at Work of the Labour Department and take necessary precautions.
When engaged in outdoor activities, drink more water and avoid over exertion. If not feeling well, take a rest in the shade or cooler place as soon as possible. Perform outdoor activities in the morning or late afternoon.
During indoor activities, replenish water timely. If there is no air-conditioning, then windows should be kept open and fans be used as far as possible to maintain adequate indoor ventilation. Public facilities with heat sheltering may also be used.
Avoid prolonged exposure under sunlight. Light-coloured and air-permeable clothing, wide-brimmed hats and ultraviolet (UV) blocking sunglasses can reduce the chance of sunburn by solar UV radiation.
Use a broad-spectrum sunscreen lotion of at least Sun Protection Factor (SPF) 15 (ideally higher) and reapply every two hours if you stay out in the sun, or after swimming, sweating, or towelling off.
Beware of health and wellbeing of elderly or persons with chronic medical conditions. If you know of them, call or visit them occasionally and check whether their household ventilation and air-conditioning devices function properly.
Those more vulnerable to heat stroke should avoid outdoor activities and stay away from hot environment as far as possible. Stay in cool, well-ventilated or air-conditioned places.
