Heatwaves are among the most dangerous of natural hazards, but rarely receive adequate attention because their death tolls and destruction are not always immediately obvious.
The body’s inability to regulate internal temperature and eliminate heat gain in such conditions increases the risk of heat exhaustion and heatstroke. The strain put on the body as it tries to cool itself also stresses the heart and kidneys. As a result, heat extremes can worsen health risks from chronic conditions (cardiovascular, mental, respiratory and diabetes related conditions) and cause acute kidney injury.
Deaths and hospitalizations triggered by extreme hot weather occur rapidly (same day and following days), which means interventions also need to be rapid when a heat alert is issued.
Heat can also disrupt and compromise essential health services, such as the loss of power supply and transport. Heat will reduce working productivity and increases the risk of accidents.
Top tips to keep cool during the heatwave:
Stay hydrated — make sure you drink lots of water
Stay indoors — close windows and curtains/blinds; use fans and/or air conditioning, if possible, even if it is only in one room
Minimise physical activity — if you need to exercise or work outdoors, do so in the early morning or evening
Check on vulnerable friends, relatives and neighbours — give them a call or pop in to make sure they are coping with the heat
If you feel faint or affected by the heat — call 000
People with respiratory conditions should follow their action plans and carry a reliever puffer with them
