Record-breaking temperatures have been logged across China, scorching many parts of the country.
This week, several people died due to heatstroke in Zhejiang province, which has recorded temperature over 40 degree Celsius.
Authorities in Zhejiang had released 10 red warnings for heat－the highest warning level in the local four-tier system－for July by Sunday, breaking the record over the same period in previous years.
An obvious sign is excessive sweating, as well as feeling very hot and unwell with it.
dizziness and confusion
loss of appetite and feeling sick
cramps in the arms, legs and stomach
fast breathing or pulse
a temperature of 38℃ or above
being very thirsty
get them to rest in a cool place - such as a room with air conditioning or somewhere in the shade
remove any unnecessary clothing, to expose as much of their skin as possible
cool their skin - use whatever you have available, a cool, wet sponge or flannel, spray water, cold packs around the neck and armpits, or wrap them in a cool, wet sheet
fan their skin while it is moist - this will help the water to evaporate, which will help their skin cool down
get them to drink water - sports or rehydration drinks are fine too
feeling unwell after 30 minutes of resting in a cool place and drinking plenty of water
not sweating even while feeling too hot
a temperature of 40C or above
fast breathing or shortness of breath
a fit (seizure)
loss of consciousness
