Kind of ironic in that Sichuan food is almost guaranteed to raise your body temperature (authentic hotpot at least). I do love those Sichuan peppers.
And BTW those digital thermometers should be ubiquitous (don’t worry they will be). In Beijing they check everyone riding the subway. Everyone boarding a plane etc. Not a perfect indicator a but a quick useful tool. And maybe the only check your gonna get in the US.
