Detailed Description

Very Hot Weather Warning

The Very Hot Weather Warning is now in force. Under the
influence of prolonged heat, members of the public should
stay on the alert to prevent heat stroke or other
discomforts related to very hot weather and pay due
attention to health conditions. If symptoms such as
dizziness, headache, nausea, shortness of breath or
confusion develop, take rest and seek help immediately, and
seek medical advice as soon as possible.

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
