People with dementia can become agitated or distressed when the temperature isn't right, but some aged-care facilities aren't designed or operated to keep them comfortable.
There are competing claims over what the optimal office temperature is. Here's what the research says.
Studies have found consumption of chillies is inversely related to the risk of being overweight or obese.
New research has discovered brain receptors that sense heat also play a hand in appetite.
When is it too hot to fly?
Major airports around the world will see more frequent flight restrictions in the coming decades because of increasingly common hot temperatures.
Sometimes only a water fountain will do.
Schools need to have a formal policy in place for how to deal with heatwaves effectively and keep children cool and well.

Global temperatures like 2015 will by normal by 2030, and Australia's record-breaking 2013 summer will likely be an average summer by 2035.
The female body should maintain warmth better than the male, but this doesn’t seem to be the case.
Australia’s had a cooler and wetter winter, but the rest of the world has been hot.

February 2016 was the hottest month by the biggest margin ever. Does that mean global warming has gone into hyperdrive?
Climate change has been implicated in record-breaking temperatures across the 20th century.
Record-breaking years have been almost impossible without human-caused climate change.
Record global temperatures, driven by El Nino, contributed to devastating fires in Australia.

2015 was the world's hottest year ever by a long shot. But what drove the record temperatures, and what role did climate change play?
A hot end of the year contributed to Christmas Day fires in Victoria.

El Niño dominated global climate in 2015, but in Australia the story was more complicated. 2015 was Australia's fifth warmest year on record, and saw the return of very dry conditions to parts of Australia.

2014 saw heatwaves of all kinds and other wild weather. Research can now explain that climate change made these events much more likely.
A measure of temperature here may be different to elsewhere.
How do we know that a measure of something in one location can be replicated precisely in another. We already have a universal measure of mass and time, but what about temperture?
The large 1982 El Niño contributed to the Ash Wednesday bushfires that killed 75 people in south east Australia.
El Niño has arrived, it's getting stronger, and it's not about to go away soon. And already there are rumblings that this could be a big one.
