Sydney experienced a dramatic heatwave on Sunday, with temperatures reaching over 40 degrees.
But things were even hotter for Roxy Jacenko, who revealed her breast cancer medication has significantly increased her temperature.
The 37-year-old opened up about her unfortunate situation in an Instagram post.

Sharing a selfie of herself at work, the Sweaty Betty PR founder wrote: ‘The joys (not) of living on Tamoxifen.
‘When everyone thinks they are hot you are literally 25 degrees hotter and cannot regulate your temp.’
According to BreastCancer.org, Tamoxifen has a handful of potential side effects.

These can include hot flashes, mood swings, and nausea.
Roxy’s battle with breast cancer began in 2016, shortly after her husband Oliver Curtis was jailed for insider trading.
The publicist previously told The Daily Telegraph she was forced to take preventative chemotherapy pills.

‘I did a test in the US which gives you a percentage (chance) of the cancer coming back and it was a bit higher than the oncologist would have liked,’ Roxy said, adding she will be taking the pills for the next decade.
‘I have a 10 to 15 per cent chance of it coming back.’
In October last year, the publicist revealed she had another scare when a doctor found a lump in her breast.

She was then forced to deal with the psychological distress that comes from a diagnosis.
‘When I went to collect (the results), I had it clear in my mind: “You have it, everything has gone so wrong, this just fits with the mess”,’ she said.
‘I was almost shocked when the breast surgeon said, “You are all good Roxy, its not cancerous”.’
