Freezers use a evaporation and condensation to pump heat out of the fridge and into the kitchen.
As the climate changes and heatwaves become more frequent and severe, it's vital we do more to understand who is most vulnerable and how we can reduce their risk.
The microbes in your gut influence how your immune system reacts to bacteria and viruses. A severe immune reaction is deadly; a small one lets the virus win. The right balance may depend on your diet.
The majority of research on how female athletes should train for the heat is based purely on what works for men.
More companies are selling products that claim to keep you cool on hot days. But it turns out that common materials used in sports clothing may not always be the best.
Wildfires blanketing several Western cities are creating hazardous health conditions. Don't count on cloth masks to protect your lungs.

A new study lays bare the average summer heat people in the UK can expect by century's end.
The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.
In South Asia, days with both extreme heat and extreme pollution are expected to increase 175% by 2050. Separately, the health effects are bad; together they will likely be worse.
Winter is flu season – could it be coronavirus season as well? The research is mixed, but other factors besides temperature and humidity have more to do with the spread of SARS-CoV-2.
A warming climate leads to more heat-related deaths. The fact some research is showing the opposite indicates we need to refine the way we measure heat-related mortality.
Air conditioning isn't the answer for everyone, especially for residents of the less affluent – and often hotter – suburbs of our big cities. But there are other ways to make hot days more bearable.
A new US study has found warmer temperatures will lead to more deaths from injury, for example in transport accidents, drownings, assaults and suicides. But what does this mean for Australia?
Hot weather can make chronic health conditions, most commonly experienced by older people, more difficult to manage. So it's a good idea to look out for older friends and relatives this summer.
The marathons in next year's Tokyo Olympics have been moved to Sapporo, because of concerns around Tokyo's extreme heat. The move, though controversial, will reduce risks to the athletes' health.
Average temperatures in Australia are already high by international standards, but what happens when they continue to rise? How much heat can our bodies withstand?
The world's fastest-growing cities are in the tropics. They are highly exposed to climate change, especially as urban heat island effects and humidity magnify the impacts of increasing heatwaves.
South Africa needs to develop low-cost housing solutions that are inherently comfortable and environmentally sustainable. Green roofs could be part of these solutions.
