Key Points
- Ang heatwave ay kapag patuloy na mainit ang panahon araw at gabi sa loob ng tatlo o higit pang araw sa isang lugar.
- Ayon sa unang National Climate Risk Assessment ng Australia, habang umiinit ang mundo, mas nagiging madalas at mas matindi ang mga heatwave.
- Sa Australia, mas maraming buhay ang naaapektuhan ng heatwave kaysa sa ibang natural na sakuna, at lalo itong delikado para sa mga matatanda, may iniindang sakit, maliliit na bata, at mga buntis.
Ang heatwave ay tumutukoy sa patuloy na matinding init ng panahon, sa araw at gabi, na nararanasan sa isang lugar sa loob ng tatlo o higit pang magkakasunod na araw.
Kamakailan, inilabas ng Australian Climate Service ang unang National Climate Risk Assessment, na nagpapakita na habang umiinit ang mundo, nagbabago rin ang mga natural na panganib na kinakaharap natin.
Dahil dito, mas magiging madalas at mas matindi ang mga extreme weather events tulad ng heatwave, at magkakaroon ito ng epekto sa lipunan, kalusugan, ekonomiya, at kapaligiran.

People with heart disease, they often are at much greater risk of having a heart attack during a heat wave, so really your body is redirecting all this blood away from the body core towards the skin surface to try to keep you cool. And that places a lot of strain on the heart.Professor Ollie Jay

Iba pang mga paraan para manatiling presko ay ang maligo ng malamig, maglagay ng malamig na tuwalya sa leeg, magsuot ng maluluwag na damit, at planuhin ang oras ng paglabas upang iwasan ang matinding init.

“In the setting where someone is not feeling better soon or their symptoms are progressing, it would be advised that call their GP or Health Direct. If the symptoms are severe, for example, if the person is experiencing confusion, they've fainted or having any chest pain, they have a very high temperature, they would be advised to call an ambulance.”
Para sa mga sanggol, mahalagang magsuot sila ng magagaan na damit, o kahit lampin o nappy lamang kung sobrang init ng panahon.
In babies under six months of age, offer frequent breast or formula feeds to keep infants hydrated. If they’re over six months age, they can be offered regular small amounts of cooled boiled water and offered cool hydrating snacks like watermelon or strawberries.
And the other really important point is never leave your baby in the car, even just for a short period of time during a heat wave. Babies can really quickly overheat.Dr Hamrosi

“It's important for people to keep in mind that the temperature that we see on the weather forecast, that's actually measured in the shade. So if you're out in direct sunlight, you can be exposed to temperatures as much as 15 to 17 degrees Celsius higher than those temperatures that you think you're exposing yourself to. So finding shade is really important,” He says.

“You enter in how old you are, what kind of chronic disease you might have, whether you have access to air conditioning. It also knows which postcode you're in, so it draws on freely available weather information,” ipaliwanag ni Professor Jay.
“It then gives you an individualised heat stress score. So it helps you understand what your personal risk is throughout the day, and we give a seven-day forecast as well. We also use it to deliver evidence-based personal cooling advice, and it helps people plan their activities.”
