High temperature does not mean high heat.
For instance: a spark from a sparkler/hand-held firework is perhaps 2000 degrees C in temperature, but if it lands on your hand you won’t feel it.
Whereas if you tipped a bucket of water at the prosaically low temperature of 100 degree C over you, it would put you in hospital.
As well, if you tipped a bucket of water at the prosaically low temperature of 100 degree K over you, it would also put you in hospital. But for a concussion.
